[A*UG] PRI and line sharing

[Brett Nemeroff]

Jim,In general, any resource can be shared between servers. However you need
to consider the impact it will have on the bandwidth.

So if server A has the PRI, but server B has the phones, the calls go from
the provider INTO Server A, then OUT of Server A (doubling the bandwidth
usage at that site) then INTO Server B.

It's done for inbound calls much in the same way you do it for outbound
calls. For inbound calls you simply dial the other server (so you'll need a
sip/iax connection between the two servers)

With more modern systems, you don't normally have to worry about hunt groups
and such. Unless of course you actually have analog hunt groups. If you do,
the same applies, but you need some way to identify which inbound call is
for which server. For analog lines, this is usually either done by an IVR
prompting the user like "Push 1 for sales, push 2 for support" where sales
could be local, but support may be Server B. Or you have to create separate
hunt groups for each Server.

I'm not sure if that helps or confuses things. ;)
