<div dir="ltr"><div>Ok, I am little confused as per the interoperability portal ,It mentions that call transfers work between Nortel CS1K running release 4 and CM 4.1 .</div>
<div> </div>
<div>Then I found CSCsc64303 which says call transfer results in No audio and is fixed in CM 5. If Cisco guys can verify that I am hitting this it would help.</div>

<div>I have integration between Nortel CS 1000 running release 5 and CallManager 4.2 sr4 , I am able to make calls between Nortel and Cisco Ip phones. The issue occurs when ever a call between two nortel phones is transferred to a cisco IP phone over the SIP trunk , I have no audio between Cisco and Nortel. I am using G711 codec over the SIP trunk. The Cisco IP Phone rings and the call is established but have no audio either side. I can see the SIP invite message and ACK messages in the CCM trace but not sure what I am missing here. </div>
