Hi Scenario is sip SIP trunk using mediation-server to SBC, signalling is fine and RTP negs ports fine from/to SBC to mediation-server, regardless of call directions.
Is there any resolution to mediation-server sending to RTP dst port 0. I am assuming this is STUN/ICE probe (or related to SRTP), I checked for WMI values but do not see anything that implys this could be changed in the mediation-server.
I was under the assumption based upon RFC's should STUN/ICE fail then the mediation-server should revert to sending RTP on the SDP negotiated ports.
For me mediation-server never sends anything except these probe packets and then RTCP reports never reverting to normal RTP stream. The SBC sends a stream without problem via the mediation-server to MOC.
Would be really useful to know how to get around this (if possible) I have seen several threads on this . with no apparent answer so far.. or what exactly does mediation-server expect to rx in response to the tx to RTP port 0 (valid STUN response?) (am using 8/08 mediation-server version) having tried the others with no success.
