[SIPForum-discussion] Help in PRACK

[Chittaranjan Panda]

18x will be retransmitted.

In the mean time if UAS sends 200 Ok final response of INVITE , it will be accepted. But there will be one way media path.

After timer expire (NO 200 Ok response for Prack from UAS ) , then UAC will send 480 or some response code according to implementation to end the call.

Other member's comment is most appreciated.

Thanks,
-Chitta

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
