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. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
