I have a client, that has a few remote office locations - and today they either have their own SIP provider and Local POTS lines or they have phones that connect into the main 6108. What they would like to have is the following:
Central UCM 6108:
SIP providers connected
Analog POTS for local backup
Remote offices UCM 6102/04:
no SIP providers Peer Trunks to the Central UCM ( over existing VPNs ) Analog POTS for local backup/Life and Safety Lines
today I have the Peer trunks setup and extension to extension calls can be made although not via pass through - every ucm has a peer network with every other UCM ( it would be good if we could set this up as a spoke and hub )
I assume that I could create an outbound route on the remote UCMs that routed outbound calls out the Peer-to-Peer trunk at each location.
What routing would I need to make the central UCM route the call that are not local or remote extensions to go out the SIP provider trunk?
I selected dial trunk but then it still expected me to select one of the extension types.
any guidance would be greatly appreciated.
