<div dir="ltr">I'm working on getting a SIP trunk with an ITSP fully functional. I can get basic calls ok but Unicast MOH is not working out - no audio. Going off-hold i get the call audio back.<div><br></div><div>Quick packet cap on the CUBE confirms i'm getting MOH packets from CUCM but they don't make it across CUBE out to the SP.</div><div><br></div><div>For the re-INVITE to get the music audio, CUCM is sending SDP with:<br></div><div><div>m=audio 4000 RTP/AVP 0<br></div></div><div><br></div><div>From the packet cap, the audio packets are not being sourced from port 4000 - they are coming in from ephemeral ports. Could this be causing an issue with CUBE not translating the streams?<br></div><div><br></div><div>The reason I ask is that I noticed a bug out there <a href="https://www.cisco.com/cisco/psn/bssprt/bss?searchType=bstbugidsearch&page=bstBugDetail&BugID=CSCtb32219" target="_blank" style="outline:none;color:rgb(74,115,153);text-decoration:none;font-family:Arial,sans-serif;font-size:14.4px">CSCtb32219</a> for ASR1K which seems close, in my case this is a 4431 (Also ios-xe) running 15.5(1)S. Anyone run into that? The workaround is to enable duplex streaming in CUCM, which seems a little goofy.</div><div><br></div><div>I dont feel like I have anything special configured on CUBE:</div><div><div>voice service voip</div><div> ip address trusted list</div><div> ipv4 blahblahblah</div><div> address-hiding</div><div> allow-connections sip to sip</div><div> no supplementary-service sip refer</div><div> fax protocol pass-through g711ulaw</div><div> sip</div><div> pass-thru content sdp</div><div> sip-profiles 100</div><div>!</div></div><div><br></div><div>dialpeers all have </div><div>!</div><div><br></div><div><div> dtmf-relay rtp-nte</div><div> codec g711ulaw</div><div> no vad</div></div><div><br></div><div><br></div><div>Thanks!</div><div><br></div><div><br></div><div><div><br></div>-- <br><div class="gmail_signature">Ed Leatherman<br></div>
