Subject: SIP client for *nix

Dear Paul,

if MS Exchange Server speaks standard SIP any *nix SIP Client should do at 
least the communication part.
I think you will have a hard time finding a TLS-enabled SIP-IM for *nix.

We (SNOM, www.snom.de) are currently developing such a client (actually a 
Linux-based SIP-phone) but it?s obviously not open source.

In case of you wishing to use it in a pure academic environment we might be 
able to help you, if you?d be willing to act as a "reference cite" (I?d have 
to confirm that with our Marketing guys).

Feel free to get in touch offline.

Regards,

 Harry Behrens
