I hope we can get ISDN in Sao Paulo - we have been told it is available 
as we are planning to deploy an Asterisk box in Brazil.

Having said this, Asterisk is what users make it.  If you want R2 
signalling (and I think a lot of people in South America do!) then 
please get on and write the module or put a bounty on it so that some 
enterprising software developer can do it for you.  In the rest of the 
world ISDN BRI and PRI are THE standard telecomms building blocks for 
all but the smallest of telephone installations, and Asterisk support 
for this is improving on a regular basis because that is what most 
people outside the US are using.

It is really only the US that seems not to understand ISDN (especially 
BRI) and there are some quirks relating to ISDN that I am sure will be 
ironed out sooner rather than later.

As regards DTMF caller ID, I think the beginnings of this option are 
already there as I seem to recall that the CVS head now has experimental 
support for UK caller ID which requires line monitoring during ringing. 
Adding DTMF is not difficult.

Rather than point out the areas where Asterisk is weak, fix it and make 
it do what you want, and add it in for the benefit of everyone!.  That 
is what open source is all about.

 Maybe, maybe not... Depending how one designs the GUI!
 
 
 
 No, I think that GUIs though needed, do limit flexibility because the
 information density is limited on the user-system direction (they are
 better on the System-user end, however).  However, this is NOT an
 argument not to package them with the project.
 
 When I was a newbie at Samba, I used to use SWAT (Samba Web Admin
 Tool) all the time.  However, eventially I discovered that it became
 easier for me to just modify the config files.  This process would
 not have occurred as easily if I had to learn the config files at
 first.  Guis are great at allowing less knowledgable people to
 administrate the server with relative competency.  They are not so
 good at allowing one to really engineer the right solution for a
 customer.  So I think both interface types are needed.
 
 Another example is X11 on Linux with lots of admin tools.  Great for
 newbies, just not the best for experts.
 

Yes, you are right!!

However, GUI for newbie's will help some people to overcome the first
hurdles, and then plunge into more advanced stuff!

One thing quote a lot of companies do is outsource the initial
configuration, because they simply don't have the technical skills
initially.  But what you want then is a way to easily go in and add an
extension, remove someone who's left, setup hunt groups, etc, etc.

It's more the general day to day maintenance that needs to be addressed,
editing really complex IVR's, dialplans, etc I think should be left to the
people who know what there doing. (Although there's nothing stopping adding
an advanced interface too..)

Just my thoughts =)

I think one thing * is lacking at the moment is a web interface to manage

that but on a simplified level (oblessly you can have an advanced mode too).

It could also integrate with the CDR, meetup, sms, voicemail functions that
exist in *.  So rather than have different projects for over view of who's
on the phone and to who, etc you have one management interface.

Just my opinion, at the moment I don't know enough about * to start writing
an interface like this.  But im sure some of the guys on the list do =)

The power of asterisk comes from its method of config. If one wraps it 
with a GUI one will inherently limit the flexibility.

Then since the GUI is what gets 'seen' people ~may~ take the lack of 
flexibility or even just the look and flow of the GUI to be a reflection

But if it was an official addon from the cvs tree (similar to the voicemail
cgi stuff), it would make take-up a lot easier =) 

That way you wouldn't make people stuck to one GUI, if they don't want it
they don't need to check it out. Its just at the moment, you've got sub
projects for lots of different GUIs, what needs to happen is someone to
consolidate what's out there and bring it all into one official project.  It
makes sense that the GUI becomes a web one, then it can run on a number of
web browser platforms.

 I think one thing * is lacking at the moment is a web interface to
 manage and add users and do anything you can do via a shell interface. 
 If it had that but on a simplified level (oblessly you can have an
 advanced mode too).

There are many of them, and most of them aren't finished.

The problem is that if you manage something on a higher level, then 
usually you loose options. But when you manage things on the low-level, 
then you don't need a GUI in the first place.


That said: I think that there is a need for a simple, well-defined setup 
method where you sacrifice completeness for ease-of-use. So I searched 
for something and after I didn't found anything that did suit my needs, I 
started DESTAR. DE is from Germany's country code. DESTAR will have some 
features helpful for german users (but non-german user won't be forced to 
use them, e.g. they will be configurable). The STAR in DESTAR is from 
Asterisk, which is basically a funny looking star symbol.



Why
---
Why do I do just another GUI?

* Because I can
* Because nothing similar exists



Why not
---
And why I didn't jump on some existing project:

* I don't know PHP, I know Perl and (preferred) Python

* I don't want to have a GUI that runs on Linux itself, e.g. in Qt or GTK
  and therefore needs file access to /etc/asterisk

* I don't want something that is just an text editor via web, e.g. where I
  can select a config file and inside the config file the section.



What I have
---

What I have so far are is a system where I instantiate various classes and
set data fields in them. E.g. something very simple like this:

EnumEntry(
search = e164.arpa
)

Or something like that:

SipPhone(
name  = hschurig,
ext   = 15,
host  = 192.168.233.67,
callerid  = Holger Schurig,
)

Those objects store themselves into a list. They have methods to check if
their variables are all set and can create snippets for the various 
Asterisk
configuration files.

For the EnumEntry, it's quite simple:

def _write_config(self):
c = AstConf(enum.conf)
c.append(search=%s, self.search)

I get a handle to an object that holds the current enum.conf file. And I
call appendValue, which appends a line to the file. For other classes, it
can be more complex. The FreeworldDialupIAXLine class writes to
extensions.conf and iax.conf.

I already use my framework to generate my Asterisk conf files. The 
generated files are working, but are crap and insecure: everything
happens in the default-context. Good enought to test the hardware, but 
nothing for Aunt Mary.



What I want
---

Those classes have static variables (which one can access even without
instantiating objects out of the classes) that give meta-info about the
objects. One can use this to write a frontend.

I plan to write a Quixote-based HTML frontend. I already can generate 
simple forms.

Maybe the Actos project uses this backend and writes a GTK based
X-Windows-Frontend.

I like the way the 3com NBX system works.  The web interface is pretty
intuitive.  Adding users and devices is a snap through the GUI but to get to
the real meat you have to edit the dial plan.  To do this, you download a

My $75,000 Avaya Definity G3Si has a GUI that simply wrapps the CLI.  If you

Their Java apps for their interaction center / ip office suck, I prefer the

A GUI for asterisk is really not that hard to make if what you 
do is model the config files in the db.  Once it's in the
DB all you have to do is the right queries to rebuild the files 
when changes are made.

Then the gui can be totaly adaptable for any use.

I think it is posible to give a good interface or better a sort of API. 
I know that bad things happen when you dedicate yourself to the GUI (ask
Micro$ucks), but you can do good things with a GUI.

 Of course, right now things 
 like * do not have an adequate reputation to pick up much of that 
 business. There is, however, a preparedness there for radical change.

When you are able to purchase support contracts on Asterisk (E.g. Yearly
(not hourly)) * will gain a lot of momentum.  There also needs to be a
released version and a lot of marketing work that goes into * before it
will be considered mainstream.  As techies and early adopters, we realize
the full potential, but often the decision makers do/will not without
paperwork and case studies.  I also think some sort of Digium VAR
certification system will ensure that the people that others hire in this
process are fully accredited and understand the technology.

Aside from echo issues that seem to be apparent with everyone occasionally
(by everyone, those not running hardware T1 echo cans) I believe * is
ready for the prime time.  Integrators however should have a better
starting point regarding what type of channel banks are
recommended, what is fully supported, which sip phones play nicely etc.
Right now it always seems to be a big finger pointing game, (which is
fine, and I do fully appreciate Digium's contributions)
but in order for it to go mainstream or production on a large scale, many
of these issues will need to be addressed.

I also don't want this thread of mine to be interpreted as a flame.  I am
very happy with the way things are right now, but am just stating my
observations of how Asterisk is different from say RedHat.

It has taken RedHat quite some time to get to where they are today, and I
am sure Digium/Asterisk will follow a similar course.

No, I think that GUIs though needed, do limit flexibility because the 
information density is limited on the user-system direction (they are 
better on the System-user end, however).  However, this is NOT an 
argument not to package them with the project.

When I was a newbie at Samba, I used to use SWAT (Samba Web Admin Tool) 
all the time.  However, eventially I discovered that it became easier 
for me to just modify the config files.  This process would not have 
occurred as easily if I had to learn the config files at first.  Guis 
are great at allowing less knowledgable people to administrate the 
server with relative competency.  They are not so good at allowing one 
to really engineer the right solution for a customer.  So I think both 
interface types are needed.

Another example is X11 on Linux with lots of admin tools.  Great for 
newbies, just not the best for experts.

Is open source IP telephony ready for prime time? Yes

On a related note, they also have an article arguing the contrary position
(see link within article). I'm too busy right now to write up a response
showing the flaws in that column but others on the list might wish to
contribute to the fray.

The opposing view had some good points, though I don't agree with 
many of his comments.

I'm not even going to try to post a reply on NetworkWorld's broken, 
ad-strewn, and ambiguous forum manager.

I think I can disagree with all of Zeus' comments except this: 
management(*) for IP telephony is just as important as the telephony 
itself.  Without the ability to measure, manage, and examine 
performance, it is a tough sell for open-source software in the 
enterprise.

Perhaps that doesn't matter, actually.  Enterprise isn't really where 
Asterisk is written and supported, so we don't see the robust 
features that an enterprise would require.  Remember: there are no 
sales brochures for Asterisk, and the CTO who is looking to implement 
Solution C or Asterisk will not have anything to use in the Asterisk 
column except for (maybe) my feature spreadsheet and an enthusiastic 
network admin who runs it at home.  This will not typically lead to 
Asterisk as the winner.

I am not saying that this is good or bad, actually.  It's neutral. 
The purpose of Open Source is not to defeat commercial 
implementations of the same features, but to provide a better 
solution for some people who want to get in there and make things 
work exactly they way they wanted, if they have the spare time, clue, 
and don't have any money to pay someone else to do it.

(*): for a quick definition of what management means, here are some 
concepts: provisioning interfaces, per-stream QoS examination, 
overall QoS examination, call routing interfaces (GUI or otherwise), 
cost control and cost examination tools, etc.   You're saying Well, 
all of that can be easily built!  Sure it can, but careful with that 
word easily.   The question is: are these components a patchwork of 
third-party tools, or is it a well-planned whole-system design?  Is 
management an afterthought?   As an example of what enterprise users 
might need, view this post and note that there have been no movements 
towards answering these items:

Again, this is not a fault that these management reports don't exist. 
If nobody develops these reports, then maybe they're not used by the 
people that use Asterisk.  Enterprise users aren't so hot on 
developing things themselves, so maybe this just languishes, and so 
they don't use Asterisk (yet?) because the combined effort of doing 
all that stuff is just more than it's worth when they can have the 
CFO sign a check for Vendor A to get it all done.

Or, maybe even they _do_ have the money to pay someone else to do it, 
but they are open-minded enough to let those hired brains help them make 
the right decisions :-)
