Hi,
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.
