[cisco-voip] PRI Alternative

[IT]

Hi,

I have a CallManager 4.0 installation at my headquarters office, and I
have a branch office with a 2801 connected to HQ with a point to point
T1. Currently, we have filled all 4 slots on the 2801.
T1- for point to point connectivity
FXO- for outbound 911 calling (we do not have a E911 server)
9-port POE switch- for all devices (which takes up two slots)

This has worked well, as have been call forwarding all their local
numbers to our Headquarters PRI.  Since they are in a different area
code, this has been quite expensive. We don't want to install a PRI on
the 2801, since it seems like to much of an expense for only 6 people. I
think the solution is to have an FXS and FXO in this 2801.  But, here
are my questions:
* I have been told an FXS card cannot handle caller-id, is this true?
* Is there an FXO/FXS on a single card, since I have run out of room on
my 2801 chassis?
* How many lines would an office of 6 people require?
* Does anyone have any other ideas?

Thanks,
Avidan
