Hello, I am trying to get the SIP Express Router going on FreeBSD 4.8 Release. When I try to connect to the SIP server from MSN messenger 5.0.0149 I get the following error message shown below, numerous times! Any ideas :) Gary Aug 4 15:08:32 sniper ./ser[618]: ERROR: get_hdr_field: bad header Aug 4 15:08:32 sniper ./ser[618]: ERROR: build_res_buf_from_sip_req: alas, parse_headers failed
