Hello all; I have a 9.0.4 IP Office running 8 sip licences, I have 5 in one group; I don't know if this has any bearing on my issues, but I'm running in Basic Mode. All calls are sent to AA, AA answers and starts its speal, then stop watch 27 seconds later, disconnects call, everytime. Outbound has never had an issue. They have a watchguard firewall and OF course the IT people "KNOW" its not their firewall. I can re-boot system, works great for about next 24 hours; then duplicate previous all over again. Jim.
