Hello all!
So we usually don't mess with phones if we can help it but we decided to tackle a job.
Heres the specs on the system:
Lucent Partner 206E Module R4.1 (x2, slots 1 and 2)
Avaya Partner ACS PROC. R3.0 (slot 3)
Lucent Partner Mail VS v5.0 (slot 4)

8 lines total (1 fax, 1 for credit card reader, 6 voice)

We ran new lines in the building, but moved the avaya boxes and punch down block without changing any wiring on the punch down block or changing extensions on the lucent boxes. We didn't drop any phone lines but we did drop a couple of extensions. Now when a number is busy, when someone calls that number, it either just rings, throws a busy signal or comes back with "All circuits are busy blah blah blah".

We're at a loss since we've never dealt with this gear before.

we've tried reprogramming hunt groups and a couple other things but to no avail. does anyone have any ideas? we're reaching our whits end and need to get the project wrapped up.

Thanks!
