VPN Help Post Reply with Quote Edit/Delete Post Report Post to a Moderator       IP Information Go to the top of this page

I'm testing VPN connection.

It is formed simplly configuration without complex. The environment is Android1.6, Sipdroid. I connected with VPN (www4.pbxes.com) through WiFi by setting on OS, and worked normally.

But, I call a Voice mail center in Callcentric as a test call, the call is disconnected within 1 or 3sec. Of course, even an inbound call is also the same with it.

I already read official sipdroid web-site but there is no description. If there are persons who know the problem or solved way resulting with it, by all means, let me know about it.

Start with the PBXes built-in echo test first.

This can be reached by dialing "*43". It should work over VPN. It would be interesting to know if the same issue also occurs when connecting to VPN over 3G instead of your local WLAN.

If our echo test works, but the trunk's does not check if you can reach it without VPN, or from other extensions, or even dialing other destinations.

Reason for such failure might be enabling "audio bypass" which does not work over PBXes' VPN service.

Thank you for your response.

I tested both WiFi and 3G through VPN by dialing "*43". But, a result is forced disconnection and is same as before.

Before the echo test announcement finishes, it is disconnected in about 3 or 10 seconds.
If I look at a System log, it seems to disconnect connection by not recognizing Audio Codecs.

Thereby, I configured Audio Codecs Option in Sipdroid to only PCMA, and I tried the echo test again. But, also a result is same.

This issue will be solved if Audio Codecs or Bypass control can be made. I think so.

Would you give me the related information to it?

Best regards

As you also observe disconnects from "*43", this is not related to audio bypass.

From looking at your Call Monitor you made some longer calls over VPN:
2010-08-18 05:05:57 1 *43 67.231. 245.210 from-internal-cont Hangup 00:00:34
2010-08-18 05:05:56 1 *43 67.231. 245.210 ext-par2 Hangup (00:00:34)
2010-08-18 05:04:53 1 *43 67.231. 245.210 from-internal-cont Hangup 00:00:46
2010-08-18 05:04:52 1 *43 67.231. 245.210 ext-par2 Hangup (00:00:46)

34 and 46 seconds.

Is this issue occurring randomly, sometimes forced disconnect, sometimes stable?

The subject of your request indicates that the issue is VPN only, or do you have the forced disconnects on non-VPN connections, too?

Non-VPN connection is very stable and very good! Thank you!

But, VPN connection is the forced disconnection every time.

And, all setting is same thing except for Use VPN in Sipdroid.

Can I show a SIP server's local log here?

Yes, sure you can publish the other SIP server's logs. However, I thought you had this issue with PBXes.

What about the calls mentioned 34 and 46 seconds long? They were sent over VPN. You said all calls were disconnected after a few seconds. This seems to be an exception to your statement.

When disconnected, do you get an error message or just Sipdroid's red call card as if the other party hung up normally?
