In my case I have a local Asterisk server, but I also use a hosted
remote IP-PBX for some things.

If I lost connectivity to the hosted service, and had no other inhouse
PBX, then things get pretty bleak. About all you can do is direct dial
by IP or SIP URI between phones inside the LAN. People often lose sight
of the fact that you can make connections directly between phones by IP
or SIP URI. Sometimes with a little internal DNS fiddling this can be
as convenient as email.

If you have your own Asterisk server (or other PBX) in-house and you
lost your SIP trunk then you have more flexibility. Your internal
diaplan should provide for internal service already.

What type of PBX hardware do you have on-site? Also what make/models of
phones?
