VOIP Service Error

One category of common call errors is related to your VOIP service. These errors are normally displayed as VOIP Service Error in the Voicent call status column. The info following the VOIP service error is specific to your VOIP service provider, though there are common error code used by different providers.

For example, you may see the following call status:

Failed. Line unavailable. VOIP Service Error: 603 Account concurrent call limit.

The “Failed. Line unavailable” is the error message Voicent software produces to describe that it cannot make the call due to line failure. The info after VOIP Service Error “603 Account concurrent call limit” is the error code your VOIP service provider returns to Voicent software. In this case, it is telling Voicent software that it cannot make the call due to your exceeding the concurrent call limit on your account. (Technically, the VOIP service error is the SIP return code and info correspond to a SIP INVITE message from your VOIP service).

Some of the VOIP service errors, like “503 service unavailable” may simply be caused by a disconnected phone number.

In almost all cases, you can get a better understanding of these errors by contacting your VOIP provider.

VOIP call has no audio

Please take a lool at my call reports. They are coming up as failed. I did a test and when picking up the line it is dead air – no message being played. I pick up the test call, it is dead air. The message does not play

Here are a few simple things to check:

  1. Remember to say “hello when you answer the call. The message play is voice activated.
  2. Make sure there is no silence in the beginning of your audio file. You can always use Voicent sample message for your testing.
  3. Make sure you have enough outbound calling credit in your VOIP account

The second thing to make sure you can use your VOIP service from your computer.

  1. First download a free software called x-lite, which is a softphone that allows you to manually make a phone call from your computer.
  2. Call your VOIP service provider and ask them to help you setup x-lite. If x-lite works and you are able to make a test call successfully, you can be pretty much sure that Voicent software will work.
  3. Please note it is better not to mention Voicent when contacting your VOIP support. The reason is that almost all VOIP services know how to support x-lite, mentioning Voicent software may just confuse them. Another reason is that a lot of VOIP services are not too eager to get customers who use automated dialer software, a few services may simply disallow such usage.


If you have to troubleshoot yourself, here are a few tips:

  1. Your firewall program on your computer may block the audio connection. To test if this is the case, try to disable your firewall program (Windows firewall, Norton, McAfee, AVG, etc), restart Voicent gateway, and see if the problem is fixed. If it works, and to make it work while your firewall program is on, please see Open firewall ports for VOIP service.
  2. Your firewall program on your router may block the audio connection. To test if this is the case, try to connect your computer to the internet directly (connect your computer to the DSL/cable modem directly without a router), make sure you can still get on the internet, and restart the gateway. If it works, you need to configure your router to allow audio connection to come through. For details, please check your router’s administration manual.
  3. If you are using a PBX system, make sure it accepts G711 U law (PCMU) for audio codec. To set up a different code in Voicent, open Voicent gateway > Setup > Options > SIP tab > Codec, and choose the right codec there.
  4. If you are using other software, such as MagicJack, on your computer, try do disable or exit these programs. They may take over the audio device and causing trouble for other programs to use the audio.
  5. Make sure your computer meets the minimum system requirements as stated in Installation FAQ
  6. If you are using a wireless connection, try to disable it and use a physical network connection.
  7. If you have multiple network adapter on your computer, make sure the primary card is set correctly. For details, please see change network adapter order
  8. If you are using cisco spa3102, make sure the telephone line is analog, not digital
