[cisco-voip] Call Preserve SIP

[Bill Riley]

Yes same bug different issue.  The bug causes me to need to use an MTP for
transfers to work correctly even though I shouldn't need one. My current
problem is that when the WAN drops I lose my call to the SIP provider so I
wonder if it is because I am using the software MTP on Call manager.

Call Manager bug

 

 

CSCtb01167

 

 


CUCM fails to ACK the 200 OK after blind transfer over SIP trunk 


Symptom:

After blind transferring a call the transfer destination gets one-way voice
and eventually the call disconnects

What is requiring the MTP? Is there an early offer or DTMF codec/media codec
mismatch?
