[SIPForum-discussion] Help in PRACK

[mustafa aydin]

Hi Sankar,

I believe the connection should tear down as per the following statement in RFC 
3262;

RFC3262;

   If a provisional response is received for an initial request, and
   that response contains a Require header field containing the option
   tag 100rel, the response is to be sent reliably.  .
Assuming the response is to be transmitted reliably, the UAC MUST
   create a new request with method PRACK.

Regards,
Mustafa Aydin

Dear Members,

When UAC sends Supported:100rel in the initial INVITE and UAS responds 
180RINGING with Required:100rel

1) What will happen if the UAC doesnt respond PRACK ??

2) What will be the UAS behaviour if it doesnt receive PRACK??

Regards,
Senthil
