Since caller never sends ACK, so destination should end call (after 32 seconds per RFC 3261) even if it does not receives CANCEL from caller.

In fact i have seen some billing systems that actually start billing upon receiving ACK from caller, rather 200 OK from destination. To overcome the loss of few seconds (between 200 OK from destination and ACK from caller), they use a different billing head called "connection charges".<o:p></o:p></p></div><div><p
