asterisk users - Feb 2009 - switchtype QSIG and Asterisk implementation

Hi,

Is Asterisk "fully QSIG-compliant"?

I currently have an Alcatel 4400 connected to Asterisk 1.2 and 1.4.
Zaptel versions are 1.2.26 and 1.4.11.

I am using switchtype=euroisdn and all works fine.
However, it seems that Alcatel's latest firmware has dropped support for
euroisdn which is really despicable. So now I need to see if I can migrate to
QSIG which is supported by Alcatel.

However, I've searched for QSIG + Asterisk on the web and came up with some
posts saying that Asterisk may not fully implement QSIG (eg.:
http://threebit.net/mail-archive/asterisk-users/msg14000.html).

Are the latest Asterisk versions (both 1.2 and 1.4, not to mention 1.6)
QSIG-compliant or are there known issues?

Is anyone here "happily" running a LegacyPBX---QSIG_PRI---ASTERISK
system?

I've read this page and it seems that the author did not succeed in setting
up QSIG between Alcatel 4400 and Asterisk:

Thanks,

ISDN is implemented is Asterisk and in libpri. What version of libpri do
you use? What version of Asterisk, exactly?

1) libpri 1.2.5 with Asterisk 1.2.30

2) libpri 1.4.5 with Asterisk 1.4.21.2

1. That is very surprising as I would classify QSIG to a private
PBX-to-private PBX protocol, not a private PBX-to-public ISDN.
If this classification is true, it would be a "commercial suicide" for
Alcatel to narrow its targeted customers to those living in countries where
Alcatel PBX are mostly sold by Telcos (in think it's the case in Italy but
not in France, for instance) as those are the only ones that can change
protocol used to interconnect with public ISDN.

So if, euroisdn support has been dropped in the PBX you're trying to
inconnect with, that may come from the company that installed this PBX and
deliberately choosed to drop euroisdn feature, for a reason.

2. Alcatel 4400 is a very old product. I'm also surprised it still gets
software updates though it was possible to upgrade it to an OmniPCX which is
the current Alcatel PBX.


3. Anyway, how is your current setup ?
Public ISDN  --<BRI or PRI> --- Asterisk ---<BRI or PRI> --- Alcatel
4400


4. From my poor understanding of libpri, Asterisk complies with parts of
QSIG standards. I tried hard to find a doc describing Asterisk QSIG features
but couldn't find anything.

That is a good question. I had the same dilemma here. Finally I am
using my OXE via Q.SIG but does not know call transfer and other
functions are implemented or not. I have found same documents as you.
Unfortunately no useful help even here nor Alcatel forums. For making
clear I am not bitching and many many thanks and respect for every
help I have received from here just I did not received any useful
answer on this topic yet.

The libpri 1.4.9 have some new features but no details. From changelog:

"2008-10-17 16:13 +0000 [r636]  Matthew Fredrickson <creslin at
digium.com>

        * pri.c, pri_internal.h, pri_q931.h, q931.c, pri_facility.c,
          pri_facility.h, libpri.h: Merging in additional Q.SIG features in
          #13454. Includes Q.SIG physical/logical channel mapping support,
          extended coding of Q.SIG name operations (calling name), and call
          rerouting support via added dialplan application."

What "added dialplan application" means in this context? New parameter
to dial? Might a new function?

Bye,
