A few months ago I began compiling a list of IP PBX products and other telephony platforms that are either directly Open Source, or are commercial products that have spawned from various open source projects. These include core open source platforms like Asterisk, Freeswitch and FreePBX, as well as commercial products developed and maintained by “for profit” companies.
I stopped counting at 101. It’s amazing to see the sheer range of choice out there for businesses and individuals seeking a VoIP communications solution. If you have developed or currently market a VoIP capable IP PBX product, and I neglected to mention you, please feel free to add your comments and I will put you on the list.

Just wonderful resource list....As U said.. let me add the most famous windows based http://www.3cx.com IPPBX system provider.
Ali - 3CX is a great product, but I did not put it on my list because to my knowledge, it does not contain any "Open Source" as part if its code base. I believe everything on my list has at least part of its genetic makeup in open source, such as Asterisk. 3CX, as well as Response Point and OCS would have been on my list had it been a more general roster. Thanks!
actually 3CX uses apache and php so I would think it would qualify
Well, Cory!...Now we hope you will also come-up with a new list of all those non-open source base programs. And of course you will add more flowers in this already existing IP-PBX basket. ;-)
Thank You Very much for sharing. It's really useful to us.
Hey Cory,
You may want to add our entVoice IP PBX appliance based on the combination of asterisk and several open source PBX interfaces.
Let me know what more info you require?
Regards,
Mitul Limbani,

Apache and php are open source, but do not qualify as "open source telephony or IP PBX". Cory's list is specifically focused on open source telephony. Actually something like 90+% of all proprietary software now contains some element(s) of open source, that's why this list is so impressive. Of course, Windows, OCS, nor Response Point are not open source even though Microsoft talks about being open source friendly and there is some amount of standards based technology being used.
Very impressive list!
But shouldn't Nortel be there too?
Martin
It's nice to see so many alternatives cropping up. Especially all the open source alternatives listed here. All the unique qualities and niches filled by these various systems can be combined by the end user or product developer to make some truly powerful systems.
On a side note, my name appears to be misspelled (it's one n and 2 s)
I'm used to it =D
FreeSWITCH should be #1, it's the best.
Diego, I agree FreeSwitch is compelling and is picking up a lot of fans in the OSS community. It will be interesting to see if FreeSwitch proliferates in a similar manner to Asterisk....most of the implementation of FreeSwitch I have come across seem to be enterprise/carrier grade stuff....which is awesome....I have not come across a lot of folks who are applying FreeSwitch to SMB type deployments and using it as an IP PBX. I have seen Freeswitch competing against Asterisk/OpenSER tandem as a viable solution for large scale stuff.
