You need to tell us for what purpose you're using these numbers? Are you selling them out to the general public? Are you using them in-house? If you're selling access to them, are you selling predominantly to individuals (i.e. single SIP devices) or to business (generally multiple devices, but often behind one endpoint)? 2 PRI lines is only 60 channels, which on a decent, modern specification of server won't be a problem on a single box. You may of course want to run the PRIs into two boxes for redundancy (one box failing won't take out all the numbers) - but this might depend on whether your PRI provider will automatically route calls into PRI2 if PRI1 dies, or whether the 2 PRIs have independent number ranges on them. > - Would one have a dedicated box that has the PRI cards configured running > Asterisk and it's only function is to handle the lines > - All other machines trunking through to the PRI box for outgoing/incoming > calls as required > - A separate machine that handles the central billing for all > incoming/outgoing > calls as per the required solution? It's up to you - all of these will work. Assuming you have no plans to grow beyond the 2 PRIs, then a single box would cope with the load (though, as suggested above, a hot spare is never a bad idea). If your long-term plans are for many more PRIs coming into a cluster of servers, probably better to plan well now with future growth in mind. That might look something like this: 2 x OpenSER boxes handling registrations - initially hot-spare config, in time as load increases you might move to load balanced 2-n x Asterisk boxes with PRIs - you'll want to look around the net at some of the performance tests with different versions of asterisk - theoretically with 1.4 you should be able to push 4 PRIs through each server, if the server's not doing much else apart from receiving calls on the PRI and firing them out via SIP. 2-n x Asterisk boxes for "extra services" - voicemail, complex dialplan scripting, etc. etc. If you're primarily linking via SIP/IAX to businesses' PBXs at their local site (i.e. fewer clients, but each with more numbers/concurrent calls), you may not need the SER boxes at this stage - they're mainly to take registration load away from Asterisk.
