From: "Venkatesh Joshi" <[EMAIL PROTECTED]>

   RFC 3261 -> section 10.3 is slightly obfuscated.

   In one instance it states that if REGISTER request has an "expires"
   parameter or if the request has an "Expires" header field, that
   value MUST be taken as the requested expiration.

   Then, it also states that registrar MAY choose an expiration less
   than the requested expiration interval.

   Does this mean that the value in the 200 OK message takes precedence ?

Yes.  Just because the UA requests a particular expiration doesn't
mean that it gets it.

The same holds for SUBSCRIBE.
