I am trying to configure an external Bogen UTI1 paging amp to an Avaya G450. I have an outgoing, loop start trunk set up with a TAC and an MM711 analog port 003v108 set up within the TG. I am using a 4 digit access code, the access code 7937 is configured in the uniform dialing plan as an AAR. In the aar ana table I pointed 7937 at route 137 and then to TG 137, I receive reorder tone and no circuit/channel available. I have also attempted the Loudspeaker Paging configuration.Obviously, I am doing this wrong. Any help is appreciated, Thanks in advance.
