Hi, I've got an issue with the way FreeSwitch is currently handling (un)Register requests.

When my SIP client performs a registration to remove all its binding by using a Contact header with a value of "*", FS generates a corresponding 200 / OK response with a Contact header with a value of "*".  My current SIP client does not like a Contact header being included the 200 / OK response in this particular scenario and flags a failure.  Is there any way to configure FreeSwitch (or its embedded Sofia stack) to prevent it from adding a Contact header in this particular scenario?

Thanks,
Mike
