UC 500 - can calls be routed via PSTN

I have a customer that has 3 sites. I'm looking at a UC 560 for the main site and UC 540 for the other 2 sites. When a call comes to the UC 560 and all 3 lines at the main site are busy, can the call be routed via the PSTN to a 2nd site, if there are lines free at the 2nd site? Or do they need to have a WAN in place connecting the 3 sites. Currently they don't have a WAN.

Yes, you can. You must configure a voip dial-peer and a pots dial-peer with great value of "preference" to remote UC.

This is an example:

dial-peer voice 100 voip

preference 1

destination-pattern REMOTE UC NUMBER

session protocol sipv2

session target ipv4:REMOTE UC IP

... omitted ...

dial-peer voice 101 pots

description POTS_backup

preference 2

destination-pattern REMOTE UC NUMBER

port 2/1

... omitted ...

Commands "preference", "hunt stop", "voice hunt" handle the hunt process on different dial-peers.

Regards.
