I setup ser 0.8.1.2 on fedora core 2. For some reason I cannot register to the proxy.

At first I thought there was a problem at the ser.conf so I disabled the Max-Forwards test. What I got then was a server error ( the sl_reply_error();) I guess that for some strange reason the proxy/system cannot decode the sip messages. (mf_process_maxfwd_header() - returns error when it cannot read the Max-Forwards header and the ser.conf script just jumps over the register process) Any help would be great.
