We found two different behaviors in call transfer.
1. If the call is transferred from DUT1 immediately as soon as the PSTN B number is dialed, ringback exists.
2. If the call is transferred from DUT1 after PSTN B started ringing, there is not ring back(MOH exists).
I have attached the traces
Call flow is as follows:
PSTN A (214 250 0685) calls DUT 1 (6468477620)
DUT 1 answers two way audio present.
DUT 1 presses transfer
DUT 1 calls PSTN B (9405358999)
DUT 1 Presses Transfer to complete the transfer
PSTN B rings PSTN A does not hear ringback
PSTN B answers call
Two way audio is present
PSTN A terminates call.
I am in Version 7.0 PR1 Software load: 13.0.0.83
I have attached the trances for reference.
Looking at the packet capture for the call with no ringback, packet 2652 pauses audio on the incoming leg
(to DUT1) through "a=inactive" for 6 seconds until packet 2964 from the Mitel takes the call off hold.
The call with good ringback has the "a=inactive" from the MiTel at packet 3473, however, audio is resumed 300ms later on packet 3500.
IP Addresses:
Mitel 3300: 10.35.31.85
MBG: 10.64.3.2
Is there any SIP peer profile settings or any other settings that can resolve this issue?
