  1. It depends if you have set IVM to use hardware or software hangup detection. It's been a while since I've used IVM, but if software detection mode is enabled, it means IVM has to be constantly listening for those off-hook tones and listen to them repeatedly to confirm that it has heard a hang-up/off-hook signal. Hardware based detection (if it works) will almost always outperform software detection. In this case, the actual modem/telephony board will detect when the caller hangs-up and signal to IVM much faster than IVM would be able to detect the disconnection itself. The biggest issu
  2. Wingmiester, I'm pretty sure your problem is unrelated, although I don't have a solution for you - sorry (it sounds like a bug though). The khz refers to the sampling rate/frequency which is essentially the sound quality. Since most telephone systems today run on 8khz audio, many Text To Speech developers make two versions of their 'natural' voices; a 22-44khz voice for desktop applications and an 8 khz voice for phone applications. Normally there is no issue with using a 22khz (or higher quality) voice in IVM or any other telephony system, but the 8khz voices sometimes sound better be
  3. You're not the only two who have contacted me /posted about this problem, and all of the cases have appeared in a very recent timeframe. I'm willing to bet that something was changed in Axon recently which is causing this to happen (I'll have to put this down to a bug because as far as I can tell there is nothing wrong with your dialplan setups).
  4. A "404 Not Found" SIP error is just like a webpage 404 error. It means the number you are dialing is not found to be a valid/existing extension or is not a valid phone number. The error is typically generated by the service provider, not the client... However, if Axon is not set to use your outbound SIP service as the default dialing plan, you will find that Axon will actually route your calls internally. In this case, dialing an external number would produce a 404 error because Axon does not recognize the number in its internal database of extensions. You need to make sure that y
  5. Judging by your other question, I think you are using the Mac OS X version. The OS X port is slightly different, and from what I've seen, does contain some minor bugs that the Windows version does not. I will say though that the mac version really does not have the large userbase that the windows version has, so it takes a lot longer to find and fix these bugs. The OS X port also hasn't been around that long relative to the Win version so it's still in the 'testing the waters' phase I would say.
  6. Well it might not be as much as a bug as just a matter of system priority. I gather you are using Mac OS X, but for just about any operating system the same principle applies. Different applications can typically be given higher priority than others in the 'Z-order', this means that if a low priority application tells the OS to bring it to the front, the OS may decide that it should still appear behind another application that has a higher Z-order priority. All this means is Express Talk probably has a low (default) priority and that for whatever reason iTerm considers itself to be hig
  7. Well you say you have a DSL connection with 10 mbit of bandwidth, but you don't specify what your "uplink" bandwidth is (I'm assuming you gave the downlink). Remember that in this case the uplink bandwidth is the most important because you are not very concerned with what the third party says to you, just what you say to them. The thing is, I also have a 10 mbit downlink... but I only have a 1 mbit uplink. That means I can only make 10% of the outbound calls I could make with a 10 mbit uplink! So, as you can see, it is very important to know what your uplink connection is rated at. Al
  8. Well It shouldn't sound like 4 kHz, but I would expect it to sound like 8 kHz as this is the telephony standard for now (except for some proprietary VoIP services like Skype). If you have a 22 or 44 kHz sound file and you down-sample it to 8 kHz, I find that it sounds a lot worse than if the original composition was made for 8 kHz playback (This is also true for text to speech and why many TTS companies will offer both a 22 and 8 kHz version of their voices). Lastly, if you are using the GSM codec, you will get cell-phone like quality & audio compression. You will find that using t
  9. Or 4. This forum community is not very active, and a significant majority of the (small) userbase are novices and probably don't know the answer. Normally I would help out, but I haven't used Axon in over a year now and I have never experienced this error before. 1. Check to make sure the dialplan appears under 'Dialing Plans' on the Axon web config (I assume you've got this far) 2. Make sure you select a default dialplan (If I remember correctly, there used to be a drop down menu at the bottom of the dialing plans page 3. Make sure the dial plans are not excluding the extension you
  10. You can click the drop-down box to see a brief history of incoming and outgoing calls. Unfortunately (despite me bringing this to the attention of NCH staff multiple times), Express Talk is severely lacking of a call log/history feature.
  11. A Delclined error is very vague, it just means the call was rejected for some reason. Keep in mind that the service provider can choose to generate whatever error code they want, so 'declined' can mean something different from provider to provider, so it is up to us to try and guess what the problem is. I'm thinking it could mean: - Insufficient funds / account balance negative - Username/password combination is incorrect - You are not authorized to dial that kind of number - The dialed number is not formatted correctly - The callee decided to screen and reject your call - Genera
  12. I agree that it is annoying. The change was made some time ago. Basically Axon went from a completely free product to something with a $$$ price tag literally overnight.. and I don't believe there was any added functionality to Axon other than more limitations. I expressed my opinions about this to the NCH staff, but it appears my words fell on deaf ears. I have since moved from Axon to Asterisk.
  13. Like DJ said, I know of other customers using Grandstream FXOs without any issues. In fact (from what I hear), it is easier to configure than the 'officially supported' SPA3000/SPA3102. There is however no guide for Axon available that I know of.
  14. Sometimes you can program this into the dialplan of the IP Phone or ATA adapter you are using, and this can be much easier than trying to come up with a round-about method in Axon. For example, almost any Linksys/Sipura ata adapter (e.g. the PAP2T) will have have a built-in dialplan option that gives you high levels of control over what numbers can be dialed, how they can be dialed, and how they should be processed before sending them to the SIP server (Axon). You could for example restrict calling to some numbers but not others (e.g. everything but 911), or you could make it a 'hot-line'
  15. In terms of PSTN gateways, Axon can work with many TAPI compliant voice boards (see the NCH website for more info) as well as networked FXO gateways like the Linksys/Sipura/Cisco SPA3000. Skype calls can be handled through NCH's uplink application (costs extra). In my personal opinion however, it is not as stable as it could be and it has not been updated in sometime (i.e. may not even work with recent skype client versions). There are alternative software packages available on the net that can turn Skype into an SIP gateway including the official Skype to SIP gateway service (there is how
  16. According to the user Megatech,
  17. Yes, I'm pretty sure under telephony settings you can select a specific OGM for each line to answer with (overriding the default OGM). Note: I haven't used IVM in a loong time, so this functionality may have been changed/removed/moved somewhere else in recent versions.
  18. You can try, although unless you are using a true hardware virtualization technology like Xen, you will probably experience sound break-ups in the conversation as the traditional 'software virtualization' technology will struggle to provide stable performance.
  19. They are pretty similar in functionality.. Express Talk has added support for Video over IP (I'm assuming Zoiper doesn't) as well as external USB phone support.
  20. After you install a Sapi voice, it should appear in the system control panel. If it doesn't, try restarting. In any case, those synthesized voices are not going to be much better than Microsoft sam. If you want a natural sounding voice, you should consider purchasing one of the natural voices from realspeak/nuance, loquendo or AT&T for example. Many of the voices can be purchased for about $30 from nextup.com. These 'natural' voices use speech concatenation to form words and sentences rather than using a tone based synthesizer. So for example, a person records their voice saying
  21. Well I don't really know what to suggest. According to the IVM 'sdk', that script should be working fine. I know that I have tested PHP plugins with IVM before (I'm talking year(s) ago though) on previous versions of the software, but I haven't actually done any testing recently. You may need to contact NCH directly about this one, or at least someone else who is making use of plugins.
  22. Ok, the first problem is that it appears you are making a plug-in call directly to a URL (which by default Windows will send to the default web browser). I don't think that will work (or at least I haven't tried) because IVM wouldn't be able to scan the output of the script from the browser, you're basically just telling the web browser to open the php page as if it was a web page. Instead I get IVM to execute PHP from the command line, as if the php script is a Windows executable rather than a web page. In other words, I would install PHP on the local IVM machine and run php.exe as the pl
  23. The issue is that there are many possible causes for echo over VoIP. It may take some trial and error to identify the exact cause of the problem. Here are some possible causes: 1) Echo Cancellation turned off - Express Talk has a built-in Echo Cancellation algorithm to help suppress some of the unwanted effects of Echoing. You can turn it on by selecting 'Use microphone and speaker and turn echo cancellation on' from the Communication Device selection under options. 2) Poor Network connectivity - Run the Network Setup Wizard in Express Talk to help solve network issues and ensure th
  24. You won't. As I pointed out earlier, you cannot use the command-line control interface to poll status requests from Express Talk. In other words, it is entirely a one-way communication system. A possible solution (a bit far-fetched): If you use the Windows API calls for handling GUI elements like textboxes and buttons, you may be able to get the text from Express Talk's status window (you would first need to identify the Window handle of the Express Talk window either by class, or better yet, using it's window 'title' name)
