I have a Freepbx installed on a Sangoma 75 with an E1 PRI Card ()
Everything is ready except outgoing and incoming calls.
When I try to call I get a Message “All Circuits are busy Now please try your call later”
When I call in the call gets dropped.
However I connect the PRI to the old PBX which is still in place and all works correctly.
I am using a crossover cable I have OK on alarms on Dahdi.
These are settings I got from he provider in Spanish, and I will post my translation as well:
Tipo de E1= PRI-ISDN
Cantidad de Canales= 15 CANALES
Tipo de Codificación= HDB3 (High Density Bipolar of order 3 code)
Toma de Canales= Ascendente
Tipo de Impedancia = 75 Ohm
Tipo de Reloj= Esclavo
Tipo de marcación: Overlap
Se le entrega los 7 Dígitos a la Central del Cliente .
