These are my 2 cents on your issue<br><br>when the transfer softkey is pressed or the conferene softkey is pressed, ccm intructs both phones to "close receive channel & stop media transmission. It Stops the RTP 2-way audio Stream<br>
when transfer/conference is pressed the second time, CCM sends a series of Open Receive Channel message to the phones and instructs the phones to Start Media Transmission.<br><br>So my thoughts are that when the transfer is pressed the 2nd time the RTPs aren't being routed to the ipc properly and they get 1 way audio.<br>

No. the calls go out our ASA via the anyconnect client (2.5.1025) out to the IPC user.<div><br></div><div>Transcoders are not being used. (checked with one of our tickets)</div><div><br></div><div>simply press the transfer say I have X on the line, transfer.</div>

<p class="MsoNormal">as far as the call setup / call flow, what is the difference
between a transfer and conference. Forgive me if someone answered before.</p>
<div>

</div>
<div>
<p class="MsoNormal">we have been having on going issues with telecommuters (IP
communicator) getting calls transfered to them from our operators. </p>

<div>
<p class="MsoNormal">Call can be transfered and we get the call connected but no
way audio (sounds like a codec issue to me But it doesn't fail.... we have to
hang up) but doing the same thing with the conference button then dropping off
the call works fine.</p>

<p class="MsoNormal">had about 3-8 TAC cases open on this and still have the same
issue. much less, but still have the issue.</p>
