Hello list, I have seen a call flow in one of UA like below.
User Agents A , B and C are connected to PBX. The call is established between UA A and UA B. Now B wants to transfer the call of A to C . first steps B press transfer button , a reinvite goes to A to put on hold in second step B completes pressing the number he gets a ring tone ( c ringing now). in third step B again press transfer button to complete the transfer of this call to A. After the third step UA-B is sending the cancel method to PBX to cancel the call which it establised . After this cancel it is sending the REFER method which contains the transfer details . Is this correct implementation , if yes can i know which RFC contain this standard. regards vlrk _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
