| Just a guess as I'm a new pbx admin....
I believe ACA stands for automatic circuit assurance and it's common to set the attendant console to receive these messages.
I believe the numbering indicates the trunk group access code and then the trunk group member.
Might want to look at your errors / alarms log to see if anything is in there.
You can also find documentation on avaya's site regarding ACA.
Hope this helps you a bit. |
