[SIPForum-discussion] Proxy..

[Andrew Yu]

Hi Praveen,

It depends on the configured polices on the proxy, which so far I've 
come across:

   1. Authentication & Authorization required for registration
   2. Registration required for invite
   3. Authentication & Authorization required for invite

Please see 20.7 Authorization of RFC3261. Thanks.
