Trying to configure FXS ports to SIP trunk for outbound faxing

Jump to solution

Hello,

This is my first time trying to configure an Adtran gateway. I'm trying to configure all FXS ports in the gateway to connect fax machines which are used only for outbound faxing, all of them have the same outbound DID. The other end of the gateway is a SIP trunk that goes to an Asterisk server, which handles the calls from the gateway.

I already have a different brand gateway doing this task in production that I would like to retire. This gateway is configured so that it doesn't have to register every single FXS port as a user in Asterisk. I would like to accomplish the same with the Adtran unit: take any calls from the FXS ports and send them through the SIP trunk to Asterisk, no registration or authentication.

Below is the configuration I have. When I try to make a call, I get a busy and nothing reaches the Asterisk server. Asterisk shows the trunk to be up.

Any help is appreciated.

Because your FXS lines are all going to use the same DID and are outbound only, you can assign a bogus extension number to each of them and use caller-id-override for the ANI. 

You don't really need SIP identity in this scenario.

voice user 11111

  connect fxs 0/1

  password "1234"

  no special-ring-cadences

  caller-id-override external-number 7730000000

  no message-waiting

  no echo-cancellation

  no call-waiting

  modem-passthrough

voice user 11112

  connect fxs 0/2

  password "1234"

  no special-ring-cadences

  caller-id-override external-number 7730000000

  no message-waiting

  no echo-cancellation

  no call-waiting

  modem-passthrough

voice user 11113

  connect fxs 0/3

password "1234"

  no special-ring-cadences

  caller-id-override external-number 7730000000

  no message-waiting

  no echo-cancellation

  no call-waiting

  modem-passthrough

...and so on

I would put a more specific accept pattern on the grouped-trunk to minimize post-dial delay.

voice grouped-trunk G01

  trunk T01

  accept NXX-XXXX cost 0

  accept 1-NXX-NXX-XXXX cost 0

  accept 011-$ cost 0

  accept 411 cost 0

  accept 611 cost 0

  accept 911 cost 0

reject 976-XXXX

reject 1-900-NXX-XXXX

  reject 1-976-NXX-XXXX

If the calls fail to hit the asterisk server at all, turn on debugging and try to place a call, then paste the output here.

Thanks for the reply. It was helpful.

The command: caller-id-override external-number 7730000000  wouldn't set the outbound CID. I had to enforce that at the Asterisk server.

All is good now.

Thanks.
