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?

We don't. I'm fwding to Jonnathan Lennox, he will possibly know more.

Note that it is not necessarily ser-sipc problem -- ser proxies the
pingtel request which may be what sips does not like.
