[SR-Users] Cancel / OK handling

[Oz Mortimer]

Hi,

I have an issue where a client is sending cancel after the call has been answered but before the client received the 200OK, I know they should then respond with a BYE based on the 200 final result, but they don’t (Meaning the call / billing stays up)..

Is there a way I can timeout a call/force BYE if ACK is not received to the 200 OK? 

I know technically this is the clients issue but they can’t / won’t fix 

Thanks is advance
Oz.
