Asterisk and Exchange 2007

Hello,

is there a posibility to connect Asterisk and Exchange 2007 directly. I have seen it with SIPX in the middle, but a direct way would be better.

Thanks

Chrsitian

i thought Asterist only supports SIP over UDP and Exchange 2007 only support SIP over TCP.
How did you manage to bridge this gap?

thanks in advance, Nir.

in bugs.digium.com, there is a project that has TCP support for SIP. Works ok, I think.
