asterisk users - Oct 2009 - Asterisk and QSIG

Hello,

I'm looking for info about interconnecting asterisk to QSIG GF enabled PABX
over
PRI .

Any information and pointers will be helpful.

The very first first question: does asterisk support QSIG BC and GF natively
i see that it is supported through CAPI enabled cards but what about support
through librip/dahdi?


Thanks
Vadim
