6. Your problem:

Hi,

There is a Trixbox server registering into a sip server. The Trixbox can be located in a public IP or behind a NAT. In both cases it can be located for sending and receiving calls.

Using the dial plan I can route a toll free number to that username, using this:

Matching Patterns
$request=^INVITE
To=sip:8001234567@

Deploy Patterns
To=trixbox_username@

My question is how do I send multiple tool free numbers to the Trixbox server location, in a way the server understands which number was sent?

Somebody ask for something similar http://www.brekeke-sip.com/bbs/viewtopic.php?t=4365 , but has not been answered.

Thanks in advanced.
