Hi all,

This is my first post to this forum and my first incursion in Asterisk.

I’m managing an IPBRICK [ ] box with Asterisk 1.4.18 and with 4-port ISDN BRI PCI card. 3 of this ports are connected to PSTN.

Before I got here the company ordered an ISDN GSM Gateway [ ]. Of course that I would prefer a IP GSM gateway.

I would like to know how can I set a call routing to go out in a particular BRI port that is connected to GSM gateway. All the BRI ports are configured in the same way, ie, they are all set as TE point-to-point so the calls are placed in the first available line.

I would also like to know how should I read real-time debugging from ISDN events from the CLI.

As I said this is my first time with Asterisk so I didn’t read the manual yet so I appreciate your help.
