[Serusers] Cisco3600 to SER

[smy at addm.com]

Thank-you all for the tips....  I was out of town for a meeting, that's why I
couldn't reply any sooner.  I will give it a shot and let you all know how it
goes.  Paul, as for the corrupt c= field, what can I do or go around 
it?!? Again, my setup is based on the ONSIP.org document which calls
use_media_session().  If this is the case, what can I do or what should I pay
attention to??

Thank-you all for your input....  If this works, I think I'm gonna start up a
HOW-TO document for Cisco 3600 and SER, and hope that all your contributions
would be helpful for both me and everyone else dealing with Cisco 3600 
and SER.

Cheers!

Best Regards,
Samuel Yeung
