ϒ⁄A customer uses a mobile number starting with 1XX to make a call to agent A, and the call is successfully established. When the call is complete, unified gateway generates a CDR indicating that agent A pays for the call.
ϒ⁄A customer uses a mobile number that does not start with 1XX to make a call to agent A, and the call is rejected.
Interaction and Restriction
The collect call service can be configured only on the unified gateway used as a called party.
Trunks supported by the collect call service include PRA, Brazil R2, and SIP:
ϒ⁄PRA: The collect call flag is carried in REVERSE CHARGE INDICATION IE (0x4A).
ϒ⁄Brazil R2: If value 8 is carried in Group II forward signals, it is a collect call.
