[SIPForum-discussion] Re-Invite with Supported 100rel + 180 ringing

[shiba shankar rout]

Hello All,

 I am getting stucked  at this scenario. Can anybody help  me on this ?

My question : Suppose i am sending re-Invite without SDP with supported
header 100rel to UAS. Then shall the UAS send 180/183  Ringing with SDP
offer for enabling the PRACK?

Please clarify my doubt.  My doubt is after a  established session , shall i
get 180 ringing for Re-invite. ?


Any suggestion would be vital for me ?


Invite---->
180------>
200----->
Ack----->
====
Re-Invite---->
180----------->
Prack----->



Does this call flow right ??


Regards,
S S  Rout
