I'd suggest turning off the sofia debug stuff cuz that's just line noise
unless you know all that stuff. You need to compare the two traces and look
for differences. I'd start by looking at only the fs console output of each
call and see if there's anything different between the two. See if there's a
point where they diverge and work your way back from there. Look at the
corresponding SIP dialogs and see if there are any clues as well. You may
also want to capture the SIP traffic with tcpdump and analyze it in
Wireshark which is easier on the eyes than having it buried in with the
sofia and console logs.

FWIW, I just updated to latest and I can't make this feature *NOT* work. I'm
on 32-bit CentOS using Polycom 550 and Snom 320 phones.
