OpenSIPs operating as a b2bua with topology hiding.
My SIP softphone (which uses OpenSIPs as an outbound proxy) receives an
incoming call, and I answer it.
I then try to transfer the call using the MI below:
:b2b_bridge:
1020.30
sip:[email protected]
1
This results in "ERROR:b2b_logic:mi_b2b_bridge: No entity found". What am I
doing wrong?
