RE: [Sip] Questions on Max-Forwards

[Loh Kok Jeng <kokjeng.loh@siemens.com>]

Hi,

Thanks for your reply.  Section 11 says:

   Alternatively, a server receiving an OPTIONS request with a Max-
   Forwards header field value of 0 MAY respond to the request
   regardless of the Request-URI.

Does it mean that a proxy may send 483 instead of 200?

What if the value of Max-Forwards is outside the permitted range
0-255?  Should a 400 response be sent?

regards,
KJ Loh
