In Understanding SIP Timers Part I, I explained the basics of T1, Timer B, and Timer F. Today I want to climb up the protocol stack a bit and write about timing from a services point of view. Timers B and F function close to the network layer and are responsible for making sure that messages are. The GSX/ SBC may release a call with this cause code if there is a timer expiry on a setup request, for example no response by the peer to a SIP INVITE message on the egress call leg. This reason code is in the default crankback profile, and will cause crankback on the next route returned by PSX for the destination.
