VOIP PBX -- 3CX, GrandStream, Asterisk ?

I have been testing Switchvox, the commercial version of Asterisk, but it costs a lot.

What VOIP PBX do you recommend for the
below so we can have $0 annual costs ?
  ** 150 phones
  ** 3 PBXes (one at each site)
  ** 18 total SIP lines (6 at each site)

An many others, including FreeSwitch --

In reverse order -----

  ** 18 total SIP lines (6 at each site)   -- No, two SIP trunks at each site from separate providers.  SIP will deliver DIDs and is measured based on Call paths, so six active calls = six call paths.    Depending on where your offices are they may be the same provider or different providers.  IPComms, Vitelity, Anveo, Did4Sale, Flowroute to name a few are all options.


** 3 PBXes (one at each site) - SuperMicro systems make great servers.  

 ** 150 phones - Snom, Polycom, Aastra, YaeLink, Digium , Cisco, Grandstream and many others. Features, complexity, durability and of course price all will factor in to your decision.  

--- I would have recommended you walk the AstriCom 2013 show floor, but it closed to day.

.. They will all accomplish the goal, the only real difference is that it has no support, because they are free.  You could still get hardware related support.. For example a digium e1/t1 card purchased gives you a basic support level for setup related issues.

I myself use open source asterisk .. With well over 150 phones.. Which I support myself.

What PHONES do you recommend ?
Free Tool: Site Down Detector

Helpful to verify reports of your own downtime, or to double check a downed website you are trying to access.

One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.

I use Linksys spa phones. 942 model
I believe Cisco may have purchased them since I bought mine though.  You can use any SIP compatible phone however.  I've used grandstream phones too.
