With my Cisco WIP310, what is happening is it is replying 481 Call Leg/transaction unknown. After that it processes the INVITE retransmission at which point it rings for 240 seconds. Which is a wee bit annoying.
This is a very strange flow. If the caller sent a CANCEL, it should not be sending any INVITE retransmissions. If the proxy received a CANCEL, it should not be sending any INVITE retransmissions.
