sounds like unixhost.com. A friend got that and it was not stable in terms of bandwidth or cpu, so if it is them (or someone that has the same capacity issues) you may find yourself having weird problems that are hard to repeat. Generally no you dont need all the zapata stuff, unless you need a timing source or want hardware support. Sounds like hardware is out of the question so it boils down to music on hold nad meetme conferences which both are popular and require a timing source (app_conference doesnt require a timing source though). If the build failed, perhaps more information about that, would be helpful, and perhaps to the asterisk-users list as that type of problem is better suited there than here. As for the service he is planning on rolling out, some people have had success using things like Xen to load a system running asterisk others havent, it boils down to system capacity. It may beta test well with one user, but toss a bunch of these systems on one box and load test each system and see. It is also somewhat difficult to provision virtual systems like that, some people may say they need only 10 channels and in reality use 2, others may say 10 and use 50. As such he will need to work on some monitoring processes to ensure that boxes dont become overloaded. Even knowing which channels do what may not be enough, codec selection can dramatically impact cpu load. I think however a bigger problem may be timing for VoIP, where there is just enough drift to cause problems. Figure on average for every channel asterisk sends a packet every 20ms. Without a jitter buffer (which sip doesnt have one) there can be a bit of swing in that number and cause poor quality audio. I am not saying dont do it, I am just saying what I think some of the major problems will be so they can be thought about and a solution figured out before customers complain. -- Trixter http://www.0xdecafbad.com Bret McDanel UK +44 870 340 4605 Germany +49 801 777 555 3402 US +1 360 207 0479 or +1 516 687 5200 FreeWorldDialup: 635378 http://www.sacaug.org/ Sacramento Asterisk Users Group
