The customer has analog trunks from a fiber circuit. Provider is att. System is ip office 11.0 basic in key mode. Using a cordless phone or my butt set connected to the analog port, I dial out and some times the call completes. Most of the time it doesnt. The trunks will ring the the analog extensions just fine when receiving calls. All of the digital phones work perfectly making and receiving calls. The only issue is dialing out on the analog extensions. The trunks are assigned to the analog extensions, so you grab a trunk immediately when you go off hook. Any help is greatly appreciated. Thanks.
