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)
