Comparing SIP Trunk Providers that work with OCS 2007 R2

There are many SIP Trunk providers that 'work' with OCS 207 R2 - some that are on the Microsoft OIP and some that are not. The goal of this blog will be to objectively compare the various providers from basic functionality to customer service to actual costs involved. The SIP Trunk providers chosen are capable of connecting directly to an OCS 2007 R2 Mediation Server requiring no additional voice gateways. I have taken the task of identifying different market SIP trunk providers an where applicable, I have written TechNet 'How-To' instructions regarding their configuration (links below).

Some of the providers I was not able to test for one reason or another. The tables below include information I found relevant and hopefully will be of use to others. Any provider who would be interested in being included in this blog may contact me atsupport@bricomp.com. Check back often as I intend to keep this information live.

OCS and SIP Trunks

Originally I had planned on writing a few 'How-To' articles on OCS and SIP Trunks here on my blog, but then the opportunity to do the writing for Microsoft on the same subject came along. I am happy to announce that my first TechNet posting can be found at http://technet.microsoft.com/en-us/ff427414.aspx titled Configuring a Broadvox SIP Trunk in Communications Server 2007 R2.
