[SIPForum-discussion] Time interval between requests

[rahul tyagi]

Hi Mustafa,

Cancel can be sent once provisional response of Invite is arrived so
this sort duration at mininum can be the time from invite sent and its
privisional response is processed.

correct me if it seems wrong.

Thanks
Rahul Tyagi
