[SIPForum-discussion] PRACK when using TCP

[Keyur Amin]

Hello All,

Is there any reason why one should use PRACK when using TCP as the transport? In my opinion, it does not make any sense to use PRACKs when using TCP. RFC3262 does not clearly mention about usage of reliable transport or TCP when using PRACKs. 
 
Thanks,
Keyur Amin
