Is it possible to get 4 digit dialing working between a CME router and a legacy PBX vai an analog fxo? I understand that i'll need to find out more info on the PBX type, but don't have that as yet. But I'm curios in general if you can get 4 digit direct dialing working under most cases?
CME router has ephone in range of 2000-2050. Pbx has their phones in range of 3000-5000. Want to be able to call back and fourth with 4 digit dialing.
I'm told Qsig nor standard T1 is an option as PBX does not have available T1 port.
The ideal interation with small PBX is is made with ISDN BRI. It doesn't need to be QSIG, regualr BRI as for pots service is Ok.
You can use any dialplan as you like as long the PBX permits. The CME certainly does.
Any further issue must be dealt when doing the installation, usually the biggest problem is dealing with PBX technicians because they are never happy doing integrations, and would have preferred selling a PBX expansion instead.
