WCF per-call service not timing out properly with an inactivityTimeout set to 1 minute

I have a per-call service set to use a reliable session (transport session) however when I set the inactivity timeout to 1 minute the timeout does not work. reliableSession enabled=true inactivityTimeout=00:01:00

When I set the receiveTim开发者_开发问答eout to 00:01:00 the client did timeout after one minute.

Why won't the inactivityTimeout fire when I don't explicitly set the receiveTimeout?

Have you checked the time out on the client configuration remember there are timeouts for both sides.
