darkfire1515 Posted October 23, 2013 Report Share Posted October 23, 2013 I am constantly having the audio of the call completely drop out after 11 minutes of talking. It seems like the call timers on both sides continue but I get an RTP Timeout soon after the drop. I need to manually hang up both phones for them to disconnect tho. (Cell phone for external and softphone for internal) These calls are dropping on all phones including physical phones. Can anybody help with this problem? It is extremely urgent! Thank you all for your help! Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted October 23, 2013 Report Share Posted October 23, 2013 That does not sound like a regular problem (11 minutes is a unusual time). You need to take a look at the SIP packets; maybe there is one party that tries to probe the session and something goes wrong there. In the logging, enable SIP call packets and attach them here.

darkfire1515 Posted October 24, 2013 Author Report Share Posted October 24, 2013 I have sent my logs via pm. Thank you for all your help trying to troubleshoot this problem. It is really weird how it is exactly 11 minutes and it is with 100% of all calls. I also have it sent to email me on an RTP timeout and I will send you the packets in the email now.

Vodia support Posted October 24, 2013 Report Share Posted October 24, 2013 Can you also send me the trace as well. Thanks Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted October 24, 2013 Report Share Posted October 24, 2013 There is a RTP timeout after 11 minutes. The phone seems to stop sending media after 10 minutes I guess, and then the PBX eventually pulls the plug. The phone (3CXPhone) should send comfort noise or some other keep-alive traffic to keep the media connection alive, otherwise it will not work with NAT anyway. Try using other soft phones, they all do that. If the call drops while you are talking (the phone cuts off the media), then there is probably a license issue with the soft phone. Maybe it is a demo license that works only for 10 minutes? Quote Link to comment Share on other sites More sharing options...
darkfire1515 Posted October 24, 2013 Author Report Share Posted October 24, 2013 Hello, I am using the 3CX softphone as a test phone from an out of office environment. (This issue is for one of my clients and I am their IT provider) This issue is occurring in office as well with physical SNOM 320 Phones. Thank you Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted October 24, 2013 Report Share Posted October 24, 2013 Really?! Then maybe there is something in the network that starts dropping packets after 10 minutes. Can you get a PCAP trace? That will clearly show what is going on. Quote Link to comment Share on other sites More sharing options...
darkfire1515 Posted October 24, 2013 Author Report Share Posted October 24, 2013 I have sent you a link to get the CAP files. The system told me that that type of file is not allowed to be uploaded. Quote Link to comment Share on other sites More sharing options...
darkfire1515 Posted October 25, 2013 Author Report Share Posted October 25, 2013 I have done a new capture with x-lite. I am having the exact same problem with x-lite as I am with 3cx. Quote Link to comment Share on other sites More sharing options...
