[Serusers] SER and SIPC (columbia uni)

I tried to use the SER SIP server together with a number of different 
UAs. I successfully used a Pingtel phone, pingtel softphone, the 
Ubiquity UA, and kphone on linux. However, when I tried to use SIPC from 
Columbia Uni I keep getting eror messages 400: Bad Request. As all the 
other UAs are working fine I assume this may be a problem with sipc. 
Have you any experiences with using sipc and ser?

I attach an error log between the Pingtel phone ( is 
trying to send an INVITE to sipc ( SER (and ngrep) are 
running on (registrations are going through fine and 
also invites the other way (from sipc to pingtel) go through ok).

Thanks very much for your help!
