Transfer fail between Avaya IP Office set and CISCO CUCM Sets

[julian.igareda]

Hi,

We have a Avaya IP Office R9.1 interconected with CISCO CUCM 9.1 with SIP Trunk. When we make a call from Avaya to Cisco and that one transfers to another CISCO, the Avaya set is put on hold and always it keeps in this state.

We have traced the call (Avaya extension is 133370, CISCO extensions are 107650 and 107643) and attached in this thread.

Any idea about this issue?

Thanks in advance.

Best Regards,

Hi there

Just curious, can you check MTP is enabled in the SIP Trunk (Page 10).
