Hi frnds....

I have a query.

Just take a basic scenario user agent A calling B via a proxy

So when "A" sends an INVITE which passes through a proxy, Will that
proxy do some authentication of user A  or will it simply forward the
request.

If there is some authentication done, then what is it? 

And if there is no authentication done then there will be a problem that
even an unregistered user can send an INVITE which will pass through a
proxy...

Please reply...

Thanks in advance

media sessions and in which RFC I can get it.

If you have any call established log based on sap and trip u can send

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.

  Subject: [SIPForum-discussion] Proxy..

  Hi frnds..

  I have a query.

  Just take a basic scenario user agent A calling B via a proxy

  So when "A" sends an INVITE which passes through a proxy, Will that proxy
do some authentication of user A  or will it simply forward the request.

   its is totally dependent on how you configure your proxy

  If there is some authentication done, then what is it? 

  And if there is no authentication done then there will be a problem that
even an unregistered user can send an INVITE which will pass through a
proxy.

  For sending a SIP INVITE its is not necessary for a UE to register

  Please reply.

  Thanks in advance
