I have two issues that may be related.
We have multiple sites connected on a frame network, these sites have Avaya PBXs with Cisco gateways. The Gateways have E&M cards for the 4-digit dial.
Problem 1) When our Delaware office (4-digit) dials another office they just get dial tone.
Problem 2) When any other office calls the Delaware office, they can establish the call but the volume is very very low.
We upped the input gain all the way with no luck. All other offices are working fine, and the PBX manufacture says that it is not them.
Does anyone have any suggestions for where can can begin looking?
