How to separate internal numbers in asterisk?

Question

Asterisk

Good afternoon, I have FreePBX distro 12.0.76.2, it has 2 trunks (1trunk and 2trunk) and 10 internal numbers. Now everyone makes outgoing calls through 1trunk, to make a call through 2trunk, you need to dial 9 and a number.
And so a question how to make that 5 internal numbers called through 1 trunk, and other 5 only through 2 trunks? without using extra 9

Answer 1

This is done in outgoing routes
. In the number template for the route there is a Caller ID section, there write a mask of internal numbers that can go along this route. For example, 1XX numbers will use the first trunk, and 2XX - the second.
Well, if you have numbers in discord, then write down the rule for each number.
Well, in general, you need to know in principle to assign different trunks to different numbers? If it doesn't matter, but you just need to use evenly outgoing trunks, then you can install an outgoing channel balancing module.
