1 year ago I made a module (res_ccomp.c) which implements CCBS / CCNR in a
Q.Sig ISDN manner (ECMA 185 / ECMA 186,...).
It is tested over BRI (Q.Sig)/ PRI and IAX as trunk.
As terminal I used SIP with Instant messaging.

It's pretty stateful (given by standard), and invasive.. but now stable.

The problem is I made an own asn1-lib for asterisk, at the same time the
pri_facility-Stuff was introduced into libpri.
My code runs under asterisk-1.0.9 .
I would appreciate to give it as protoype for further integration.
