|
Hi
Other side is a Huawei C&C08 Local Exchange.
I compared Asterisk Trace with C&C08 Trace
Asterisk side I see ROSE_ETSI_EctInform then ROSE_ETSI_EctLinkIdRequest then Invalid Call StateAt C&C08 I see "OPERATION.........Begin3PTY" and then Invalid Call State
My Asterisk version !.8.11.0 and Libpri 1.4.12
If I enable 3PTY( 3 party call supplementary service on C&C08) will help?
Regards
babak

Asterisk is attempting to push the tromboned call back to the telco switch.
However, as shown in the fragment of the call, the peer is rejecting the transfer request. Either the peer is not provisioned to allow it or it just does not supportthe functionality.
