Dear Gents
Our 81c Nortel has analogue CO trunks provided by the TELCO Company. There is an analogue COT pilot line configured for incoming calls to the MMail auto attendant. The auto attendant is working fine until today that I noticed whenever I call the pilot CO Trunk, and the auto attendant answers to please dial the extension, I dial the extension but I dont hear a ringback tone from the PABX extension line. The called party extension answers no issues. When I used and test an extension to extension calls, ringback tone is okay. Cannot hear a ringback tone only for Incoming calls using the CO trunk. Only happen today.
I used to hear the ringback from the extension whenever I used the incoming CO trunk before.
Any inputs and advise please.
thank you and regards
