Hey community members,
Let's say I have 3 companies behind my UC500. Each company owns 4 POTS lines from carrier.
Company 1's POTs are connected into FXO 0/1/0 - 0/1/3
Company 2's POTs are connected into FXO 0/2/0 - 0/2/3
Company 3's POTs are connected into FXO 0/3/0 - 0/3/3
For inbound calls, I simply created octo-dns called Main for each company and did a connection plar on each voice-port to the respective octo-dns. All phones will have their one internal extension dn and sharing the Main dn for their company.
For outbound calls, how do I make sure that if a Company 1 user picks up his phone on his internal extension dn to dial outside, his calls will use FXO 0/1/0 - 0/1/3? and Company 2's outbound calls to use 0/2/0 - 0/2/3? and Company 3 to use 0/3/0 - 0/3/3?
