[SIPForum-discussion] Sip Status: INFO many times

[Aman]

Basically INFO method is used by a UA to send call signaling information to
another UA with which it has an established media session. This is different
from a re-INVITE since it does not change the media characteristics of the
call.

INFO body may be signaling information, a midcall event, or some sort of
stimulus.

Cheers,
Aman
