I just got a very interesting Anonymous comment to my last post. One of my BIG questions was answered:
Kamailio or OpenSIPS?
For me that question was answered - OpenSIPS. Star2Star has purchased a block of consulting time from Voice System for OpenSER support. We used it once to flush out a bug in OpenSER 1.2. Other than that we have it for a little business security. It's nice to have an official avenue for support. Plus we like (financially) supporting Open Source software. It gives us so much, we should give a little back.
Anyways, this last post makes it pretty clear: OpenSIPS is Voice System's product. That's all I needed to hear. Thanks Anonymous commenter/blog reader!
