anyone know if they have added Codec g723 and g729 support?

For the first problem, is it not possible that the user is entering a non-existing extension and Axon then transfers to that 'extension' and then the call is dropped? As a fix, you can specify a range of values that can be accepted, and if the user enters an incorrect extension they are asked to input the extension again.

 

As for the second question, I'm not exactly sure what causes dropped calls. I myself have only experienced them a couple-few times with VoIP and usually it could be explained by an interruption in the internet connection of some sort. I suppose it could also be caused by limited bandwidth (e.g. if several calls are competing on the same Internet connection, and that connection is not very high bandwidth, some calls could simply drop-out after not being able to successfully relay the SIP messages / audio to the server and back maybe?

 

Is the second line you have with the same company using the same voip server? e.g. if the host name is sip.voipserv.com, is the second line also sip.voipserv.com? If not, it could indicate that the new line is using a new updated server which could be using a newer version of the SIP protocol that perhaps NCH software does not fully support (perhaps?), if it is the same I cannot think of an explanation right now.

thanx for the reply..... my second line is with the same provider..... the error i am receiving is Sip not supported Codec... i contacted the provider which is inphonex and asked if they had the setting on both my lines the same and they said yes the it could be a problem with the equipment... but I'm not sure if that is what they are just saying to pass blame on someone else.....

here r all the problems i am currently having............... 1st i have few clients who say when they call in and enter in the extention they r hung up on.... next issue is i have been dropping alot of calls latly which i am currently doing a few test to see if it's the phone of software or provider..... net i tried to setup an additonal line and it when a call xomes in it says sip not supported media which is weird because the other line works and it with the same company... so any ideas??????????

i am currently using inphonex...

 

 

here is the issue i am having...

 

My outgoing OGM is really Chopy and i have tried just about everyhtin other then changing Service provider which is something i am currently thinking of doing....

 

i have tried a new computer

i have tried opening up ports and forwarding them... not sure if it did anything??????????????

i have tried a new router.......

 

only thing left is service provider..... thats what i'm going through....

i am using them too and also had the choppy problem.... it turned out that my choppy problem was the router i was using. i purchased two diffrent basic linksys routers and both had issues... so i decided to give the biz addition a try.. it fixed my choppy problems but have been faced with a whole mess of new issues... now i have alot of dropped calls which i am in the process of narrowing down where its the phone, computer, software or provider... i'll let you know how i make out...

There are a few online port checkers here: http://www.google.ca/search?q=port+checker

I'm not sure how reliable they are though.

i found out the problem with the choppyness... looks like it really doesn't like the basic routers.... i had to buy linksys biz routers and it seemed to do it... but now i have an other issue with the new router... now i'm dropping calls so not sure what that could be.....

thanx again........

 

I'm going to try to plug it in directly to the modem tonight while we r closed.. I'll let you know how we make out.... as for bandwith.. am running on 6 to 7 MB download and 1.5 to 2 MB upload... that should be more then enough... also if bandwith was an issue wouldn't i notice it on during my calls??????? because my calls r fine the only problem is is the OGM being choppy... I'm starting to lien toward the software being the problem.... i believe if I'm running my phone lines through AXON and am not experiencing any issues and only on the IVM program.. then i would guess that it would have to be a software issue... but I'm not giving up yet... going to try the modem thing and if i have to I'll set up another VOIP number through a different company to see if there is any diffrence.... lets hope for the best....

i think i have found out what the problem is... i think its the router.... i unpluged everything and connected the modem directly to the computer and its gone... so i guess the router is the problem... how do i check to see if the ports are open? or do u think i should try other ports? any suggestions?

You could try plugging it directly into the modem to test. If you still encounter a problem there could be other factors (possibly out of your control) that could cause choppiness, including: distance to the VoIP provider's server, the bandwidth available on the provider's end, your ISP's set-up (whether it will detect and prioritize VoIP traffic for you), etc.

thanx again........

The most probable cause of audio quality problems such as choppiness is your firewall blocking communications. I know you said you forwarded the ports, but I'd like to test this. Please find the "DMZ" feature on your router (if applicable) and set-up the IVM computer on the DMZ. This is very much like forwarding ALL ports (note: this could put the computer at risk, but this is only for a short period of time to test). If the problem is still encountered than it must lie somewhere else, and if it is no longer a problem it is likely you did not forward all the ports necessary.

 

Also, if your router supports QoS (Quality of Service) you should definitely enable it and set it up to prioritize VoIP traffic over anything else. Without QoS, VoIP traffic is trying to compete with regular INTERNET and network traffic and will be held in a Queue at the router in a first come first served basis. This is no good for practical VoIP applications since when the data is in queue it will cause choppiness as there are many small delays and short bursts of silence. Nowadays it's common for many routers (both for home and office) to support Quality of Service.

 

Choppiness is also an indication of a bandwidth problem. i.e. there is too much data to stream through your INTERNET connection at one time. Another way to solve the choppiness is to use another codec that reduces the bandwidth usage. Using a low bandwidth codec will slightly reduce the audio quality (as in clarity) to that similar of a mobile phone, but it will also avoid the choppiness. To change codecs, go to Settings -> Telephony -> Line properties -> Advanced Tab -> Prefer Lower Bandwidth

thanx for getting back to me.......

i tried the DMZ setting and made no diffrence.... i went in found the Mac address and set it up in my router for the highest priority to that mac address and also no change... batting a thosand.... also made the change to the quality and also nothing... so at this point not sure what else i can do? would unplugging my whole companies network and plugging the phone computer directly into the modem be a good test?

i went through all the pages looking for a answer that would work for my problem and nothing seems to work.... my out going message sounds really choppy and nothing seems to work...... here is what i have and what i have tried....

i have a PC with XP 1.8 G it originally had 512 Ram i upgraded to 2 GB and no change..... this is a deducted PC for the phone system.....

i have tried a new router... currently using a linksys WRT54G...... i went into it and directed the port Forwarding 5060 to 5070 and 8000 to 8002 to the assigned PC..... and no change....

Currently running Ver 4.07 of IVM....

I am using Inpohnex....

i did a INTERNET speed test .... i average 6 MB download and 2.5 MB upload so i don't think that is the prob...

my out going message was recorded using Text2speach....

Does anyone have any ideas what could be causing the prob????????

i am currently using inphonex...
