[asterisk-users] Yet another processor question

Here's my setup, I'd like to hear what everyone suggests is the best route:
I have three sites, a main and two outlying buildign, each has a Mitel
SX200 system with a PRI interface. The outlying sites currently each
have a PTP T1 line back to the main site.
Right now I have a P2 700mhz Asterisk server at each site with a Digium
4 port T1 card. Each Asterisk server sites between its site's external
T1 line and Mitel switch. Each Asterisk box is also connected to the
PtP T1 line. I am using ZaptelPPP to send data on 12 channels, and the
rest are left free for voice calls. The Asterisk boxes do some limited
LCR, and route outbound calls over the PtP T1 to whichever site has the
most affordable outbound calling plan for the call in question, as well
as sending site to site calls over the PtP.
It works, but using ZaptelPPP is a bit of a pain, and it makes upgrading
a hassle, since I haven't found ppp packages for a recent OS so now I
have to have the compiler on each box, etc. Making changes to the
asterisk servers means taking down the data connections as well, which
is unpopular with the users. One site has never worked, despite having
identical configuration to the other site. The data bandwidth is always
limited to 12 channels, even when the voice channels are idle.
So what route would everyone recommend? I can move the PtP connections
to independent WAN routers with QOS, then the Asterisk boxes will need
to do TDM to SIP and back. Right now everything is TDM switching. Will
the slow P2s have the horsepower to handle 12 or 13 TDM to SIP calls?
Or should I stick to my current system and just deal with the upgrade
hassle? (I wouldn't even upgrade, except that Caller ID Name information
doesn't work on my current 1.0 version)
