I am thinking perhaps it's not difficult to set up some software on the

office login to a VOIP software and it connects to the server, the

work. That's only my imagination, I am still searching for such
software.
Certainly THIS would work: set up VPN on the server and both office dial
into the VPN before they start to use some SIP software. This can solve
the problem, but I think it's over complicated.
Besides, I never tried VPN on Linux, only did it on Windows: on windows
the downside is once a host has dialed up VPN, local network connection
is hidden for it, that I can no longer access the hosts in the same
office that has not yet dialed in the same VPN. This is not acceptable
for us.
If you go with VPN solution you can use openvpn - that way you can
setup exactly which IPs you want to route trough the vpn, and then any
p2p VOIP software should work. Plenty of them for linux (including
GAIM). You can setup Jabber server and use it. servers:

Or you can take a look at http://www.asterisk.org/
For me it seems that the bandwith shortage is the first problem to solve
or cope with.
If Skype does not work solely because of bad connections to the Skype
Network, this is ok and you might try with a peer to peer client for
testing, if direct connectivity works better.
A quick google showed IHU (I hear you). There is also an rpm for 10.2
on packman. The description says, that it works without using any
session protocol.
Otherwise, imho, if Skype does not work ok, hardly anything else will
do, especially not a SIP connection, not to mention multiple concurrent
SIP connections at the same time.
With Asterisk you get a superior PBX Solution that handles anything you
can imagine. So you might benefit from Asterix in your internal networks
at the respective locations, but, sadly, the IAX (Inter Asterix
Protocol), from what I saw, does not offer you better bandwith usage
than SIP, so Asterix might not be the obvious solution to handly your
bandwith issues.
