Dear Support Community
Here is a case topology:
<analog phone>---<h323gateway>--IP---<CUCM>---IP--<6921>
When I call from 6921 to analog and then transfer the call from that 6921 to another IP Phone in the system, transfer succeed. But when I do transfer of the call coming from analog to 6921 to another ip phone in the system I meet the following issue: I cannot press the Answer softkey on the phone. I do, but no reaction. The codec in the pah is 711.
Your help is highly appreciated.
