[SIPForum-discussion] Help in PRACK

Sun Dec 5 02:32:30 UTC 2010

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
