<p class="MsoNormal">Good evening all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">A colleague and myself have discovered an issue where a Blind transfer has one-way audio.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The scenario is as follows:<o:p></o:p></p>
<p class="MsoNormal">IP Phone to IP phone call<o:p></o:p></p>
<p class="MsoNormal">Transfer to off-net mobile via SIP Trunk (via CUBE)<o:p></o:p></p>
<p class="MsoNormal">Blind Transfer<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When the remote person answers the phone, there is audio heard on the remote party, but nothing on the IP phone.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The SIP trace SDP appears OK. The IP addresses seem to be c=IN IP is correct.
<o:p></o:p></p>
<p class="MsoNormal">The web page for the phone reports Stream = Not Ready.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><br>
Cheers<o:p></o:p></p>
