What is the lowest end machine to run a production asterisk server.

Currently I have an MTE version running on a $2500 server.

I want to get a single Tenant asterisk server for one company but don’t want to waste a $2500 server for one tenant.

Do you guys have any recommendations for a unix machine specs and pricing..granted everything is rough estimates.

  • Depends on a lot of variables. I’ve got some old 1.8GHz 1U servers running
    hundreds of calls.

    How many calls, how much transcoding, etc etc.

    You can run Asterisk on a Linksys WRT router, so I guess that’s about a

  • Well..

    I would say that there would be about 40 Polycom Soundpoint IP335s


    I would like to restrict this to say 15 inbound lines and 40 outbound lines.

    Probably looking at 8 concurrent calls.

    But I need it to be reliable machine since it will be a production server.


  • Any x86 machine currently in production could do 10x that load. A single
    Xeon under 2GHz would be showing nearly zero load for that.

    Reliability and load aren’t really related. You could buy something like a
    refurb HP server with SCSI drives and dual power for next to nothing and
    see excellent reliability. We have dozens of DL360/380 machines in
    production with excellent reliability. My reliability items are:

    SCSI drives (small, but reliable)
    RAID 1
    Redundant power
    Lots of fans
    Server class hardware from a quality vendor

  • I spec’d out a DL380 for a client a couple of years ago. He balked at the
    price so I found a used SuperMicro on Ebay for US$150 including shipping.

    He was skeptical until I pointed out the SuperMicro was less than the
    sales tax on the DL380. I suggested if he was unsure he could buy 2.

    He did. We put them in separate datacenters and now he has complete
    redundancy. The SIP provider automagically provides the switchover.

    There’s a lot of ‘outdated’ hardware out there for very cheap dollars.

  • This doesn’t add up; you say ’15 inbound lines’ and ’40 outbound lines’,
    but 8 concurrent calls. What are these ‘lines’ going to consist of, and
    what will they be used for when they aren’t being used for calls?

    The amount of load you are talking about could be handled by a small
    Soekris box, a router running OpenWRT, a SheevaPlug, or any number of
    tiny, low power embedded devices. As Carlos already said, *any* decent
    x86 box produced in the last five years would be able to handle this
    without any noticeable CPU load at all.
