Back to the original problem reported against CounterPath and Polycom, XTRN-361: Phones fail to SUBSCRIBE. We believe that the UAs should not fail to respond to the UA challenge received after a Proxy. It has been suggested to me that the second challenge could be viewed as a failure of the first challenge. That is not my understanding, but I'd like to put the possibility out there. Are we condfident that our behaviour is correct, and the behaviour of both Polycom and CounterPath is wrong? -Paul [email protected] _______________________________________________ sipx-dev mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-dev Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-dev
