I have a uc320w device with 4 fxo lines. Our original routing table was FXO==>AA==>Timeout_To_Shared_Extension. Since the timour delay would not allow a 1 second delay in the AA, I decided to change the routing table to the following: FXO==>Shared_Extension. Since making the change, we have had ~1-2% of inbound calls get disconnected when the call is answered. Our employees state that they receive a busy tone on their handset, while the inbound caller hears a "click" followed by the "if you'd like to make a call...please hang up or dial the operator..." announcement from the telephone company. Can anyone offer any suggestions here since we really don't want the inbound delay the AA imposes?
For some reason, each and every time I select the 1 second delay and save/apply the configuration it reverts back to 5 seconds...which is unacceptable for our inbound calls. We upgraded to the 2.3 firmware before we setup this system.
