We worked with Mike on Friday and have him up and working via a hardware MTP on his router until we can implement a code that has the fix for the bug below. Ideally we want to have a setup at the end of the day without MTP.<br>

CSCsu72615 Bug Details<br>
CUCM fails to prack second 18X<br>
Symptom:<br>
CUCM 6.1.2<br>
When working with SIP provider we can get a 180 ringing contains an SDP.<br>
<br>
If you get a SDP in a 180 ringing, and it arrives before CUCM sends a 200 OK for a previous PRACK you can run into issues where your call gets disconnected.<br>
<br>
CUCM needs to respond to the PRACK, but we don't.<br>
<br>
Conditions:<br>
6.1.2<br>
SIIP trunk to provider with out MTP.<br>

You have a codec negotiation issue:<br>
May be your SIP provider is runing GSM or some weired codec.<br>
<br>
ret2=0, codecMask2=4, bytes2=20, negot2=1, dtmf2=6<br>

delay media to slow start case, codec negotation is not done<br>
