i think i encountered something like a bug in chan_sip (asterisk 1.2.5
stable). i have here a registration from 2 clients, one x-lite and the
other asterisk both registering to a ZTE softswitch.
here is the x-lite register:

take special interest in the nonce value, asterisk is using a blank
nonce. this issue does not exist in asterisk version 1.0.9...
can anybody point out where this went wrong? i have been reviewing
chan_sip.c lately to try to create a patch but i can't seem to find the
problem. anybody with *experience* out there? (asterisk 1.2.7 came out
but no mention of this in changelog) i'm stuck with 1.0.9
