asterisk users - Aug 2004 - asterisk and qsig

Guys,

I need to make asterisk connect to another device over a pri using QSIG 
signalling (master/slave). Is this feasible and has it been done before?

Thank you!

al.

I am planning on doing something similar but with a Nortel MICS...  apparently 
there is rudimentary QSIG support in Asterisk, but unfortunately the MICS 
won't do QSIG unless you tell it it's outside of North America (which I 
presume will screw up all the standard progress tones we Canucks are used 
to) :-)

Nortel does have something proprietary called MCDN which I am hoping to 
reverse engineer enough of to be able to light the MWI on their phones.

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 13:15:06.330: ISDN Se1/1:15: RX <- BAD FRAME(0x02017F)
Aug 18 13:15:06.987: ISDN Se1/1:15: TX -> SABMEp c/r=1 sapi=0 tei=0

Aug 18 13:15:09.022: ISDN Se1/1:15: TX -> SABMEp c/r=1 sapi=0 tei=0
Aug 18 13:15:09.355: ISDN Se1/1:15: RX <- BAD FRAME(0x02017F)
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.

Hi everybody,

Now we are looking to interconnect * with a Philips PBX using an S0 interface
and the QSIG protocol.

Looking in the wiki I see that's possible to define the switchtype as qsig.

Somebody have had any experience integrating * with QSIG?
Are QSIG fully integrated in *?

Regards.

Hi All. Somebody works with asterisk linked in ISDN PRI with protocol QSIG
with some PABX as Siemens, Philips, etc. The applications as pickup between
asterisk and the PABX function? The names in the display and the number of
the origin also? Which features that they can be used between the
equipments?

Best Regards

Josu?
