Using a FXO gateway as trunk

Hello, I have a planet FXO 4 port gateway
I am using freepbx 3.0
I don´t know if I should add these analog ports using custom trunk or dadhi trunk
Thank you

Is this an external device or a card in the system? If it is an external device you will probably connect to is using SIP. If it is a card in the system and is supported than DAHDI.

This is an external device

I will try to add a sip trunk,
Thank you Alan
I’ll let you know

Are you aware that you will need to login to the GUI of the VIP-480 and configure it too? I have never used this device so I can’t help you there.

Hello Alan
The status of the sip trunk is “unmonitored” (CLI sip show users)
In the status page I can see:
Ip Trunks online 1
Ip trunk registration 0

Yes. I am and I have done so
Thank you

Post your trunk config from FreePBX.

I have just added to peer details the qualify=yes string and now it says OK when I execute sip show peers (CLI)
I have checked the logs of asterisk and found this:
[2013-09-10 18:33:03] NOTICE[2002] chan_sip.c: – Registration for ‘[email protected]’ timed out, trying again (Attempt #66)
[2013-09-10 18:33:03] WARNING[2002] chan_sip.c: Remote host can’t match request REGISTER to call ‘[email protected][::1]’. Giving up.

It’s on a fixed IP registration is not needed.

Also you should not need any authentication.

Lastly, do you have g.729 licenses installed? Why would you use a low bit rate CODEC on a LAN?

What should I delete from the “peer details” ?
I am not familiar with codec carachteristics, Which should I use?
Thank you

Your CODEC should match, ulaw or alaw is fine (use region appropriate).

You should not need any authentication parameters, don’t overcomplicate.

I don’t know your gateway, key is you have to match it to Asterisk.

Check sample sip.conf for the version Asterisk you are running. It contains all the SIP peer variables and explanations that you can use in the FreePBX trunk module.

Remember FreePBX controls Asterisk, don’t modify the config files directly, it’s just a reference.

Ok for the codec
You say that I don’t need any authentication parameters because I am using a gateway in the same lan?
I deleted the register string as well as secret and user
In the status page it doesn’t show any more the trunk connections line
How do I know if the trunk is working?
Thank you

For trunk status use the qualify operator?

Did you look at the docs ?

The status of the trunk is ok
I have checked the log file:
