<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>If the call works until the phone is answered, then it is probably media/capability related.<BR>
<BR>
First, is this the call flow?<BR>
<BR>
IP Phone --- CUCM --- SIP Trunk --- IPIPGW --- SIP --- CUCME --- IP Phone<BR>
<BR>
Now these questions:<BR>
<BR>
</SPAN></FONT><OL><LI><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>What is the version of CUCM?
</SPAN></FONT><LI><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>Do calls fail in both directions?
</SPAN></FONT><LI><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>What is the region setting (what codec) between the CUCM IP Phone and the SIP trunk on CUCM?
</SPAN></FONT><LI><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>Is the CUCM SIP trunk doing early media (is the “MTP required” checkbox checked)? <BR>

<BR>
Right, the question is, how do you configure it correctly?<BR>
<BR>
What would cuz the audio to not cut thru and the call to drop... I was suspecting codec, but it is G711 all the way thru (hard coded on each dial peer)<BR>

There is no CUE.<BR>

This is a SCCP phone on a CCME, and a SCCP phone on CCM with a SIP trunk to an IPIPGW, and a SIP dial-peer to CCME...<BR>

<BR>
CCM on one side (SIP trunk) and CCME on the other (SIP dial-peer)... call worked, but as soon as you answered it dropped.<BR>
<BR>
I changed the SIP dial-peer from the IPIPGW to H.323 (no session protocol) and RTP cuts thru fine...<BR>
<BR>
Am I misreading something, is SIP to SIP not supported, or is my config retarded?<BR>
