[asterisk-dev] Challenging a sendonly INVITE

Is there any circumstance at all where it makes sense to challenge an INVITE
which is putting a call on hold?


I can find nothing in 3264 that suggests it, but wondered if:


Phone A -> Phone B (in doing so phone A may have been authenticated)

Phone B later goes to put phone A on hold


The only authentication Phone B has had prior to this interaction is the
implicit REGISTER challenge response that may have been several minutes ago.


Is that good enough?


Many thanks.S.
