Since Asterisk was mentioned in the Edge Router thread, I'll mention another less known but featured open source product called SipXecs --- see www.sipfoundry.org. We have been running a 40 phone pilot on it since January and plan to expand to about 100 in December. It is backed by a commercial version called OpenUC -- see www.ezuce.com. Unlike some projects like this, the open source version is fully functional and featured. eZuce has a flat fee model for Education based on student FTE that gives access to the commercial product. Details are on the sipfoundry web site. A big benefit with Asterisk and SipX is that you can use 3rd party phones such as Polycom and not be stuck with vendor specific phones and hence stuck with a particular vendor. If I decided SipX was not working for us, I could switch to Asterisk or vice-versa without the huge phone replacement costs. Tony Wyland Messiah College wyland@messiah.edu

We are running SipXecs in production for about 900 phones.  It will soon replace our aging Nortel PBX.  We use Polycom phones and AudioCodes gateways with it.

This is good to hear.  I looked at sipXecs a couple years ago.  I just couldn’t find the amount of support for it that made me comfortable implementing it in our environment that I could with Asterisk.  I’d love to hear more about your implementation after you replace your old PBX.

 

Thanks,

Brian
