How to associate extension with trunk?


I’m looking for a tip - I need to associate one of the extensions with 1 trunk or outbound route.

I have SIP ATA with T.38 fax support and I want that all the calls from this extension to be dialed the same way as all other calls (9+number) but those calls should be sent out of the single trunk which supports T.38
For all other extensions 9+number should direct calls to outbound route which includes a group of trunks.


like this? (shameless plug)

Exactly. Thanks a lot!
