Good evening all, A colleague and myself have discovered an issue where a Blind transfer has one-way audio.
The scenario is as follows: IP Phone to IP phone call Transfer to off-net mobile via SIP Trunk (via CUBE) Blind Transfer When the remote person answers the phone, there is audio heard on the remote party, but nothing on the IP phone. The SIP trace SDP appears OK. The IP addresses seem to be c=IN IP is correct. The web page for the phone reports Stream = Not Ready. Does anyone have any tips or thoughts on this issue? Have tried a number of config changes with respect to supplementary services on the CUBE, and MTP etc on the CUCM Trunk. Cheers Dana
