6-22 17.10 Server UDP Only Needed but Flip-Flopping TCP

[salesengi...@gmail.com]

Hello Everyone,

We have a customer of which needs all SIP and RTP traffic to be UDP throughout the length of their calls. We have a phone group with all UDP only settings in place. These phones are both in call queues and out of call queues. The calls are originally coming in as UDP and stay UDP until MoH is initiated. At this point in time it switches to TCP. 

How can we get this to remain UDP throughout?

I stand to be corrected, but MOH is controlled by the Freeswitch media server, which is integrated with Sipxcom. We experienced a derivative issue where voicemails longer than 60 seconds could not be left because the ITSP was not seeing any bearer path from the voice server and terminated the call. The workaround is documented here http://wiki.ezuce.com/display/sipXcom/Allowing+Voicemails+Longer+than+60+Seconds+to+be+Left+from+External+Callers.

There is a Freeswitch bind-params setting that controls the transport setting for the call - it goes in the sofia.conf.xml file.

Just a thought ...

Peter
