I'm faced with the need to create forensic test data for an Exchange 2007 server with unified messaging. Microsoft has a list of tested PBX and IP gateway products that are known to work (below) but I'd prefer to use Asterisk if possible. From everything I've read it appears that since Exchange uses SIP over IP and Asterisk uses SIP over UDP this will not work. I don't have a lot of experience with Asterisk but I know that many of you do so I was wondering if anyone knows of a plan to allow Asterisk to run SIP over IP or if there are any SIP gateways that will make this conversion. Reading through the Asterisk/Digium documentation and the asterisk-users list archive didn't turn up any clues. Anyone have any ideas? http://www.microsoft.com/technet/prodtechnol/exchange/2007/productevaluation /sysreqs.mspx#pbx Thanks in advance, Brian Lawrence -------------------------------------------------------------------- mail2web - Check your email from the web at http://mail2web.com/ .
