New Rock’s MX100G-S SIP-ISDN Trunking Gateway with T1/E1 ports is compatible with unified communication solutions, such as Asterisk. In this application note, two popular applications and their related configurations are described:
-  Connecting MX100G-S and Asterisk server in the same LAN. 
-  Directing incoming calls from ISDN to AA system of Asterisk server via MX100G-S.

Connecting MX100G-S and Asterisk in the Same LAN

In this scenario, MX100G-S and Asterisk server are in the same LAN. A static IP address is set on MX100G-S whose T1/E1 ports are connected to the ISDN lines.
After the following configurations, the MX100G-S can direct the calls from Asterisk server to ISDN for outbound.

Configuration on MX100G-S

On Routing > Routing Table page, setup the routing rules for directing calls from Asterisk to ISDN via T1/E1 ports.

Configuration on Asterisk Server

On extensions.conf file, edit dial plan configuration for Asterisk.
   [default]
   exten   =>_9x.,1,Dial(sip/${EXTEN:1}@192.168.250.99:5060)

Directing Calls from ISDN to AA System of Asterisk server via MX100G-S

In this scenario, MX100G-S is connected to Asterisk server, and given the AA number on Asterisk server is 8888. The incoming calls from ISDN are directed to AA system of Asterisk via T1/E1 ports and an IVR prompt will be announced to ISDN. Callers on ISDN side can dial extension numbers after they hear the IVR prompt.

Configuration on MX100G

1. On Basic >System page, select RFC 2833 in the DTMF method field.

2. On Routing > Routing Table page, setup the routing rules to change all called numbers to 8888 and send them to Asterisk.

Configuration on Asterisk Server

On extensions.conf file, edit dial plan configuration for Asterisk.
