I see. Thanks for the info. However, adding a second parameter to the call doesn't seem to help. Here's the output of ser when I check for config errors. I assume many other function signatures changed as well because sl_send_reply(), record_route(), append_hf(), loose_route(), save(), lookup(), and t_relay() all fail now. Anyhow, I changed my ser.cfg to this and still get the errors.

ser.cfg shouldn't be corrupt because I'm using ser.cfg from the berlios cvs server in the <ser-source>/etc/ directory. I did update the call to mf_process_maxfwd_header to include the second parameter.

Commenting out the MF section surpresses that particular error but then all the other errors relating to sl_send_reply, t_relay, append_hf, etc, etc still occur.

Yeah, that was the first thing that popped in to my mind. I'm using RHEL3 with kernel 2.4.21-15.0.4.ELsmp Here is what I've done to get a fresh copy of the source from berlios rm -rf ./sip_router export CVSROOT=:pserver:anonymous@cvs.berlios.de:/cvsroot/ser cvs login cvs co sip_router Before compiling I did a find /usr -name "ser" to be 100% certain that I didn't have any ser modules floating around on my system. The end result is the same old start up errors. For now I'm back to using 0.8.99-dev7 only because I need to have this SIP proxy up for a demonstration.
