IP PBX feature comparison - Avaya IP Office vs pbxnsip

pbxnsip and Avaya IP Office are both IP PBX servers.

So what is the main difference in the feature set?

Well the main one I can say straight away is that Avaya IP Office is a traditional PBX with an IP interface on it. It is not written using the Open Standard SIP protocol, instead it uses proprietary software and hardware to achieve the same as pbxnsip.

In the short, it does not give you the freedom to buy any IP based SIP Phone (Snom, Polycom or many of the others), SIP Gateways (Vegastream, Audio codes, Sangoma, Dialogic or many of the others) or even deploy it on your own server hardware and operating system.
