Maybe I need to ask Tim then: Do I need to use a different set of credentials for the Android/BYOD instead of the ones that are attached to the VoipO provided ATA? I was under the impression, based on earlier postings, that the SipDroid configuration would operate simultaneously to the home ATA. Both would ring, and whichever one I answered first would get the call. Not sure how that would work if there were different user names and passwords registering. Unless we're talking about just using a different server. Which is what I was wondering. If instead of using sip-central01 that a different server should be used? Things that make you go hmmmmm.
