We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.

PRI – NET VS PRI CPE

The signalling type should be PRI – NET or CPE depending on whether you’ll be acting as the telco or as the customer. So NET corresponds to acting as the telco and CPE (customer premises equipment) means you’re taking acting as a host / customer to the telco.

The switchtype should normally be National ISDN 2 unless your telco says otherwise.

Line coding,Framing ,signalling type ,switchtype (Card Sangoma + PABX AVAYA)

Salah satu kesulitan yang saya hadapi pada saat mengintegrasikan Card E1 Sangoma dengan line E1 PABX Avaya adalah pemilihan Line Coding, Framing & Signaling Type & Swith type. Akibat pemilihan option yang salah akan menyebabkan tidak bisa call oubound:D Setelah bertanya ke support@sangoma.com & beberapa testing issue ini sudah solve.

1. Line Coding &  Framing = hdb3,crc4 ( /etc/dahdi/system.conf)
