We have a CUCM and third-party system transfer issues.
Call Flow: PSTN----->GW----->CUCM----->SIP Phone-----> Press button:Directory(Find the phone number of the third-party system corporate directory)-----> Transfer
Calling number:A
Called number:B (sip phone number)
Transfer number:C(Press phone button:Directory, to Find the phone number of the third-party system corporate directory)
A call to B(call leg one), B transfer to C(call leg two). Result: A cannot connect to C successfully. A is held, B is connected to C.
I wants to merge call leg one and two through API or other methods.
Please help me!
