B is a prepaid subscriber and has conditional call forwarding set for busy (FTN = C)
Subscriber A calling to subscriber B. SSP will send MT IDP to SCP. SCP sends RRBCSM with T_BUSY in interrupted mode after this it sends CONTINUE. The subscriber B is busy.
In this case whether SSP will send ERBCSM(T_BUSY) to SCP before forwarding call to C?
