[Asterisk-Users] asterisk and qsig

[aleph lammim]

Well,

I've temporary connected asterisk to a Cisco E1 (which is configured to use 
QSIG). Cisco debugs show:

Aug 18 13:15:05.973: %CONTROLLER-5-UPDOWN: Controller E1 1/1, changed state 
to up
Aug 18 13:15:05.989: ISDN Se1/1:15: TX -> SABMEp c/r=1 sapi=0 tei=0

Aug 18 13:15:10.032: ISDN Se1/1:15: Event: received NL_REL_IND

I suppose the question now is: how easy is it to hack libpri qsig? I find it 
interesting that it's not been implemented yet, one would think alot of 
people must have needed it at some point in time. :)

Any feedback, pointers, reports about previous efforts, and opinions about 
complexity/timeframe required are absolutely welcome.
