a B2BUA doesn't necessarily need to be in the media path.

if SEMS SBC may fit your needs: you do not set enable_rtprelay in the 
SBC profile, you can set SEMS SBC to be signaling-only. you can enable 
SIP auth in the profile. you can use syslog CDR to write CDRs to 
syslog and then post-process from there; alternatively you can program 
your own CDR generation on top of call control interface (or, for 1.4, 
prepaid interface), adapt the rest module and use some web app server 
or similar. additionally you get stuff like session timers, codec 
filter, header manipulation etc.
