I have an ext 256 at a remote office that fwds to mailbox 250 at the main office only on busy fwds n/a works properly. I have tried analog networking codes in form 22 to no avail. We are using pri cards at both locations going over a fiber point to point and two adtrans.
I have tested other offices that work and have copied it's programming to this site exactly but it's still doing it.
