how to config CoS that extension to use specific FXO on outbound

Hi Filip

Pleas note that each Class Of Service has one Route Selection
Each Route Selection has Outbound Route
Each Outbound Route has at least one trunk

So please set:
1. Channel Group which will use this FXO channel/s ( SETTINGS=>Telephony=> Channel Groups )
2. Telephony Trunk which will use that Channel Group ( PBX=>External=>Trunks )
3. Outbound Route which will use that trunk ( PBX=>External=>Outbound Routes )
4. Route Selection which will use that Outbound Route ( PBX=>Class Of Service=>Route Selection )
5. Class Of Service which will use that Route Selection ( PBX=>Class Of Service=>Class Of Service )
6. Extension which will use that Class Of Service ( PBX=>Extensions=>Extensions )
