[cisco-voip] Call Preserve SIP

[Bill Riley]

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? 


Best Regards,
