Thanks again for your help so far, do they pay you for this ? Dual IP Address not working To report the bug to them directly, will I need to pay for support ? One Way Audio Seem to have got some improvements between the server and the SIP gateway - I don't really know how, because I haven't changed anything. Call performance is intermittent though, sometimes the audio just doesn't work. (To clarify : I've tried the 'prevent forwarding odd ports' option, but it has no effect.). No audio between anywhere and the softphone at the moment (If it rings). I'll get a siptrace up here for both axon and ET ASAP. Extensions not ringing Well, some developments... After rebooting the pc with the softphone, the extension will ring again. After a VoIP blind transfer from IVM the softphone will ring indefinately (beyond the point that the caller disconnects). The phantom call can be picked up, at which point it instantly disconnects. After this the softphone no longer rings - but it still sends outbound dial requests (which do get answers, but there is still no audio). I can see that axon is sending the INVITE messages to it. Rebooting ET, the softphone, alone has no effect. On-Hold not working Express talk isn't set to use IMS (I can see the logic behind your suggestion, that hold request must be starting somewhere). Before I could even try it though I'd need to buy the business version, which I would (I'd buy serveral, infact) - but I've already gambled on the software I've already purchased and its lining up to be my worst investment to date, so I don't really want to stake any more . It wouldn't be a viable fix for the hardphones either. The on hold player is on the server and should be connected to axon. It is axon that should be providing and intercepting the MOH though surely - could this be a bug ? It certainly seems to be in Axons product description that it provides this service. I will query my VoIP provider again, who have been very helpful and provided replies to 14 support tickets in the time since starting this thread, usually within a few hours, often less than one, all for my measly £4 a month. *cough cough*. I don't really want to leave them either, as on top of the great support the fax and sms services work brilliantly. They also operate some crazy idea where you don't pay (well, more than the call cost) to talk to tech support - how mad is that ? it'll never catch on... Curiosity : High CPU Usage Weird huh A straight up question : Are these products and technologies really suitable for commercial use ? Thanks again.

Thanks, taken me a while to get through those Dual IP Address not working - Yes. Axon does not bind to the first address even if it is set using the 'Use static address and static mapped ports' option. One Way Audio - The way the IPSec is setup for all purposes consider it as a firewall. (Actually it's a protocol - but thats not what its being used for on the server). Enabling or disabling it seems to have no effect on any aspect. - Network setup wizard on the server does not report any problems, and does not seem to behave differently using STUN,uPnP, or static IP/port binding. I seem to get better performance with the 'static IP/port' option at the moment so I am using that. This appears to be two way at the moment (EDIT: Within 30 mins of writing, I'm now getting no outbound audio, don't know inbound status. - (Call from mobile phone to IVM on server) Nothing has been changed.)- but just how consistent this situation is I'm not 100% on, i'll probably need to call it every 15 mins over the course of a day and make a note to get a good idea so I'll do this at the next opportunity. - Network setup wizard on the softphone (phones in the development office on the diagram) reports 'symmetric NAT/cannot autodetect'. I am using the setting 'Use static address and static mapped ports' with the external IP address of the office and SIP port 5060, RTP ports starting from 8000. Registration with Axon occurs perfectly - 'Registered as sip:NUMBER@IP' shows up on the phone. The phone also shows up as connected in the extension list on Axons web manager - it does show up as XXX.XXX.XXX.XXX:63640 (This high numbered port changes sometimes on re-registration) - where I would have expected 5060... this could be part of the problem ?. - I cannot put the softphone in the DMZ at the moment though I will attempt to create a situation where I can, as the router is on a different subnet (192.168.0.X) from the internal network (192.168.1.X - DHCP provided by the server). The diagram should show the situation - consider most things from the 'development office' perspective, going through the server and then through the router. The router is effectively acting as a modem. - There are no software firewalls on any workstation, (Windows Firewall is disabled by Group Policy - the server is also a W2K3 domain controller). There is no firewall on the development office server, only NAT. - The only firewall is at the router/modem (192.168.0.1) which port forwards 5060 and 8000-8100 to the server (192.168.0.2). I will refresh the diagram ASAP to reflect some of this further detail. Extensions not ringing -As indicated above, registration occurs. -No errors are shown during the registration process (Nor at any other time either). -Networking setup wizard results as indicated above. On-Hold not working -Ok, is there any way to force Express Talk/Axon not to communicate hold information directly to the VoIP provider ? Or more importantly any connected device - as the IP phones may well not offer this sort of option. I have quizzed my VoIP provider about this and they took a look at my line and informed me of the following (quoted from a support ticket) : "Your PABX is currently asking us to put the call on hold, rather than putting it on hold itself. You would need to configure your PABX differently." FIXED : Cannot use DNS Name on Extensions - One down ! (Thanks ) It was missing the port off that caused this (i.e. i was just saying 'mydomain.com', not 'mydomain.com:5060'). I wanted to use a DNS name incase I ever needed to move the axon server as part of expanding the infrastructure and would not want to have to issue the new IP to everyone using the system. Curiosity : High CPU Usage This might not be related to any of the problems at all, just an observation. I was performing some routine health checkups and caught axon using 50% of the servers CPU at highly regular intervals. Axon certainly wasn't 'doing anything' i.e. no calls, only 2 extensions registered. Is this normal ? What is it doing ?

Hi All, I am having numerous problems getting a new VoIP telephony system working with an assortment of programs - I have been trying to solve these problems for 2-3 months now but am having no luck, sometimes I fix one, and it breaks another - Hopefully someone out there will know the answers to my problem. Here is a diagram of my setup : - The orange lines represent communications of an internally developed XML protocol. This is a standalone system, and is working. - The green lines represent general web traffic. This is a standalone system, and is working. - The blue lines represent VoIP traffic. This is a standalone system, and is not working. To give you a general overview of how the system works, (This is just for background reading, without problems) : Developers are housed at the central development office, and some also work remotely. Each of them can access the central management server either via a web interface or thier desktop client which provides them with thier tasklists, auto-timesheeting etc. Currently all voice communication is done via normal landlines and mobile phones - what I want to do is create a system where calls can be directed to the correct developer (they work on different projects and clients should be passed to the correct developer). To do this I have set up Axon, IVM, VRS + IMS, on the central management server which houses amongst other applications a webserver, dns server, database server. The IVM directs users through a few menus and uses an internally developed plugin to determine the appropriate extension to pass the user to. This part of the IVM system communicates with the management system perfectly fine and is working well. The central management server is housed remotely in a data center with a 10MBps synchronous connection. The OS is Windows Server 2003. IPSec is the only 'firewall' as such. The box has 2 IP addresses (.76 and .77) on 1 NIC which is directly connected to the internet. The SIP Provider is aql - using single VoIP line. So, onto the problems : Dual IP Address not working When running Axon on the server, it incorrectly sets its Public IP Address to use the second address (.77) when it should be using the first (.76). Using uPnP, STUN or manual override (and in any combination of the three) on the networking page of Axon has no effect. This has numerous strange effects including not answering/ringing for calls at all, one way audio, no audio - seems to vary. This fault is quite easily overriden by removing the second IP Address from the NIC. This is not acceptable as a permanent solution - however, it is a slightly lower priority as the other issues persist despite this quick-fix. One Way Audio Have had this in all sorts of strange ways since setting the system up. Currently, an inbound call will ring through Axon to IVM, be answered, and will have bi-directional audio. (But this has been 'on and off' so to speak). Audio from a softphone in the development office now has no audio in either (Hard to confirm outbound) direction. I have toggled every different setting on the Axon line and tried several of my VoIP providers outbound proxies at thier reccomendation - Nothing has been effective and simply leaves different variants of the same fault (i.e reversing the direction which can be heard). I have tested disabling the IPSec which effectively means the central management server has no firewall. this does not seem to have any effect whatsoever. What would be most useful is if someone could confirm what the firewall settings should be used at any applicable point (i.e Central Server IPSec, NAT Routers, Development Office Server) VRS has proven useful in getting some sort of insight into this issue - VRS seems to record both directions of audio in all circumstances. Extensions not ringing This was not always the case, but currently even if directly passed through Axon (using 'ring on' from the voip line) or called via a transfer from IVM, the softphones at the development office do not ring. On-Hold not working Anything that causes 'on hold' / 'ringing' to start, or any position where the on hold music from IMS should play, is instantly 'taken over' by music I presume to be from my VoIP provider. This includes pressing the 'hold' button (back when the extensions were sort of working), IVM starting a transfer, or using a group/queue set to use the IMS on hold player. This problem probably has a lot to do with my VoIP provider but what I wonder, is why does the signal to hold ever get as far as my VoIP provider ??? Cannot use DNS Name on Extensions (FIXED : See later post) When using a normal SIP gateway, the DNS name (+ possibly the port) is entered into the server field. If I enter the domain name of the central management server (which is working correctly, as it works for web/xml management client) - the extension will fail to register. Is this intended behaviour ? What if I ever wanted to put axon on a different server !? I have been searching the forums quite a lot for the last 2 months but am really at a dead end with a lot of these errors. If anyone can help me solve these problems I would be VERY appreciative as they are driving me nuts !!! Thanks in advance.

Hi, I have not yet solved the problem. My VoIP provider are looking into it. I'll update this thread if there are any developments. I am having *numerous* problems getting the whole network to work, so I will write up a new thread with all these issues when I have the time.

Some developments. Alike to a an issue I faced initially with Axon/IVM - the calls dropping during hold seem to be due to having multiple IP's on my Servers NIC, Axon detects the wrong IP (and nothing will seem to force it to accept that is is not using the other). I can only disable this temporarily so is there any official word from NCH about this sort of situation ? What is annoying is I seem to have one-way audio now (no outbound), so I've sort of ended up going full circle... Can't tell if this is from ET on my local machine or at the Axon level on the server... I think it might be axon actually because now I'm not even getting audio from IMS lol... I'm in a bit of a tight spot because I want to buy IVM Pro, VRS Enterprise, IMS and a few ET Business editions - but I just can't go ahead with it until I've seen everything work, I can't afford to have my telephony mess up further down the line.

Not sure if this is Axon, Express Talk, or even my VoIP Provider's fault - but for some reason if I hold a call, some odd music plays for the caller (this is NOT the hold music I have set on ET or Axon) and then after 5-6 seconds, the call is dropped. Playing around with the options has lead to some equally weird situations such as hold working, but not being able to speak/transmit after resuming and hold working but not being able to resume at all. Most everything else seems fine. Audio is bidirectional, and of good quality. Running Axon 2.0 and ET 3.06 (problem also occured on Axon 1.31). Axon on a W2K3 Server box @ a remote location. ET Running on a PC behind a NAT - but then, why should NAT be the problem if the line works fine otherwise ? VoIP provider is aql. On a side note : How come VoIP seems to need to make a notification of 'hold' status... surely it would make more sense to mute the mic, and stream audio down the same channel without messing with the fragile SIP protocol ? Thanks in advance.

Hi, Is it allowed to connect to your PBX via domain name ? (like a SIP Proxy... which is all I figured Axon fundamentally was ?) I can connect fine via IP Address but should I ever wish to move the PBX server it would be a big hassle to update all extension softphones to a new IP Address. Current setup : Windows 2003 Dedicated Server running Axon + IVM AA. All other extensions (softphones) connected over internet, intended for use in a 'virtual office' setup. Single Network Interface Adapter is directly connected to internet backbone, and has 2 IP's. DNS name has been in working service for 6 months and works fine for mail, ftp, pings correctly, etc, also checked with DNSStuff and has no errors. Originally I was getting all sorts of problems regarding failing to register (between both Axon and the local IVM and a remote) due to having multiple IP addresses and Axon 'apparently' binding to the wrong one. These have seemingly stopped and IVM + Softphone now connect fine* to Axon, via both IP's *bar one 'seemly minor' issue, we'll see when I test with more softphones. If I dial another extension, i.e IVM from the softphone, I get no audio, though the call does get answered and IVM is running the correct proceedures and can evidently hear the tones (dont know if they are DTMF or VoIP-INFO) from the softphone - effectively a one-way audio problem, though im sure I've set every part of the both firewalls correctly. (EDIT: I have a feeling actually that the firewall may well be wrong) Input on this would be great too. Thanks in advance.

Thanks Don, I have checked the audio being correct via the VoIP - As it turns out, some of them did refuse to play back, but they were deeper into the OGM menu - this is not the fault causing the landline to fail. (Behaviour *should* be identical for PSTN and VoIP anyway, as far as the IVM is concerned, I can't see why it should even want to know whats on the other end, nor should it matter) I've gone a bit further in trying to work this out an installed Axon for line testing. The VoipTalk account now works, but the DrayTel account still does not. Ive absolutely triple-checked the details on all lines. This has been absolutely fruitless because IVM won't connect to Axon - Yes I've checked every password and setting, I'm just getting 'Server localhost did not respond to register' - Same error as with the DrayTel line (and previous, VoipTalk). I've tried with many extensions, passwords, at both ends. I've even tried using the proper domain name (This server has two IP's directly connected to the internet, with fully-qualified domain names) I'm sort of at a loss now, why on earth can't IVM connect to Axon which is running right next to it (so to speak) ?!? Could this be anything to do with having two network interfaces ? I notice it gives me a private IP ending in .76 (IP1) and a public IP ending .77 (IP2). By the way, as a note to the developers for Axon, don't use strings as ID's* - use numbers - On the Axon web interface, if you enter a VoIP line with a # in the name, you can't edit or delete it (loses the part after the # at some point in the request). I had to reinstall to reconfigure a line ! *at least, certainly not strings the user can enter.

Thanks python, Yeah - I've seen sound issues from RDP before. I've kinda put the theory on the back seat a bit because of the way it is working correctly over VoIP. I suppose I should mention the server has no audio devices. I am certainly not getting any audio (from IVM simulations, WMP, Anything) via RDP - even though it just uses some strange emulation driver. I'll look into TightVNC, but I'm quite fussy about consistency so I keep my third-party apps to a bare minimum Afraid I can't get to it physically though, its about 100 miles away locked up in a data center EDIT : You've given me an idea though, because the server does have remote control hardware which just feeds the VGA signal over the network, which is as good as being there (no RDP or any software, pure hardware implimentation)

Hi, I've been playing around with IVM all day and I've not managed to get it to work. Its quite frustrating ! My setup is IVM AA running on a Dedicated Server (Windows Server 2003 Box - Remotely Hosted). Connection to telephone system is via VOIP, provided by Sipgate. Server is managed via remote desktop and does not feature any form of sound - so running the 'simulation' is not viable. Read on however and it should be apparent this doesn't matter... What happens is, when I dial in from a landline, The IVM answers the call but no audio is heard. The IVM can hear the end user though because it responds to key presses and will happily record voicemail if I set it up to do that. Just wondered if anyone had any experience of this sort of fault ? Current 'Debugging' Action Taken : NAT/Routing/Firewall Server runs configured IPSec, no other firewall. Direct 10Mbps connection to the internet. 2 Static IP's, not NAT routed. Tried turning all security/port blocking off via IPSec. No Change. Double checked by using Xlite client on the server, worked fine, IPSec or not. VOIP Test Tested system via VOIP Only. (Xlite running on my local machine). Everything works fine when connected directly via VOIP, Reliable and responsive. VOIP Provider Integrity - Other Applications XLite client from previous test then used to recieve a call from a mobile, and a landline. In both tests bi-directional communication was 100% successful. Alternative VOIP Providers Added alternative VOIP Lines. This annoyingly wouldnt work at first due to what I believe to be a separate problem with multiple interface IP's. No other lines would register correctly, DrayTel and Voiptalk both fail to connect at all (devices dont register with SIP). UPDATED : Got VoipTalk working via Axon - confirm both PSTN and VoIP communication to IVM to be correct. Believe original issue to be solved now - have other problems but will repost about those. My current feeling is something is incompatible between Sipgate's PSTN system and IVM. UPDATED : This is beyond all reasonable doubt confirmed as the problem now. Thanks in advance.
