[HELP] Sangoma A101 E1 configuration

Asterisk Asterisk Support
1

Hi,

I want a Sangoma A101 card in NT mode to simulate a public E1 line, but I can’t get it to work properly.

I’ve been testing it with a E1 controller in a Cisco 2801 configured as a CallManager Express and it won’t work. When the C2801 is connected to the telco’s E1 it does work. When I use the C2801 as a gateway to a CallManager it does work with both the A101 and the telco E1.

Pri-debugging in Asterisk has the following output:

When setting up a call from Asterisk, the following is sent to the C2801:

When the C2801 is a gateway for the CM, it replies:

When the C2801 is configured as CME, it replies:
