[SIPForum-discussion] Proxy..

[Praveen Bhukya]

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

Hi All,

 

I want to know in which situations sip is using SAP (session
announcement protocol) and TRIP (telephone routing over IP) Protocol for
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
me.

 

 

Thanks,

Dev
