<div>Hi all,</div><div><br></div><div>I'm trying SIP Trunk between CUCM 7.1 and FS. Unfortunately MTP is not an option, what leaves me with a whole lot of problems.</div><div><br></div><div>The one I'm currently banging my head with is hold.</div>
<div><br></div><div>I do not have the traces here, I'll have my hands on them tomorrow... Meanwhile what happens is the following:</div><div><br></div><div>CISCO -> FS</div><div><br></div><div>->INVITE - no SDP</div>
<div><-Trying</div><div><-Ringing</div><div><-200 - SDP</div><div>->ACK - SDP</div><div><br></div><div>At this point the call is setup and things work as they should.</div><div><br></div><div>Cisco tries hold with freeswitch</div>
<div><br></div><div>->INVITE - SDP with IP 0.0.0.0</div><div><-200 - SPD as usual</div><div>-> ACK - no SDP</div><div><br></div><div>the call is On hold, freeswitch is playing MOH</div><div><br></div><div>microseconds later, cisco tries to recover the call and connect to its MOH server:</div>
<div><br></div><div>-> INVITE - no SDP</div><div><- 200 - SDP as usual</div><div>-> ACK - Valid SDP pointing to a moh server</div><div><br></div><div>At this point freeswitch continues peacefully to play it's own MOH</div>
<div>Cisco is sending RTP but FS is ignoring it</div><div>From this point on the call is lost and will remain on MOH until someone hangs up... any atempt to recover the call fails.</div><div><br></div><div>I'm sorry for the lack of traces as pcaps, i'll add the tomorrow...</div>
<div><br></div><div>Have someone gone through this problem or have any idea on what can i try?</div><div><br></div><div>Best,</div><br clear="all">Wesley Akio<br>TuntsCorp.com<br>
