Posted: Tue Apr 04, 2000 4:43 am Post subject: [Asterisk] Cheap Solution (Round 2)
Well, if you're looking for Voice mail type applications, there are dozens
of good voice modems, coupled with vgetty and some control software, and
they'll do a great job cheaper than a *Jack.
OTOH, if you're like me, and working on a phone system with things like call
forwarding, trying to ring the handset and then go to voice mail if no one
answers, etc., then the *Jack cards are very useful.

Last week, I posted a request for information about using Asterisk with
POTS, and the Internet PhoneJack was suggested as a possible solution.
I looked at the card, but I'm still not sure that it will do what I
need. (Looks like it does the reverse)
I need something that I can connect to an incomming household line
(POTS) that will accept calls and present the caller with a simple menu
system that also has voicemail capabilities.
According to the PhoneJack specs, the RJ-11 port is a line-out for a
POTS phone that you connect to it for the purpose of making IP telephony
calls, but I need something that can receive calls.

Use a voice-capable modem..?

One of the reasons that I don't like POTS and PSTN as designators
for the line type is exemplified above - it's easy to mix them
up. In the telephony world there are specific names: FXO and
FXS. FXS - the foreign exchange system - is what the Internet
PhoneJACK does. The FXO - foreign exchange office - is what you
are asking for, and the Internet LineJACK does that. We call
that port a PSTN port - the PhoneJACK has a POTS port.
The difference boils down to this: who provides the line voltage
and dial tone? The PSTN/FXO port does not, the POTS/FXS port
does.
For your application, you are looking for the capabilities of our
Internet LineJACK. But, as I've said before, if *all* you want
is an analog interface for "traditional cti" then our card is
overkill and likely will cost too much for your application.
However, if you are after Internet Telephony capability - ie, the
ability to do compressed, low latency voice over the open
Internet - then the Internet LineJACK is unsurpassed in the low
density market space. It would be a great choice for that kind
of use.

Right now you have two options -- wait for the Lucent Winmodem driver to
be turned into a kernel driver, or at least something close enough that it
can be reasonably select()'d on, or find a full duplex modem (not just
full duplex speaker phone) that is supported by Linux natively, then we
can support it.
Asterisk does not currently support half-duplex channels, and
fundamentally this is the problem with half duplex devices like non-full
duplex sound cards and modems. It may be possible to graft half duplex
support into Asterisk at some lower levels without modifying the API, but
I'd like to have some discussion about this first..
You can try the LineJack, someone on the list was able to get it to work.
You guys who bought the LineJack might want to suggest to quicknet that
the follow through on their statement that they would send a card.

That's what the LineJack does, but it's not officially supported because I
haven't received a card to setup outward dialing, etc.
For your application, you are looking for the capabilities of our
Internet LineJACK. But, as I've said before, if *all* you want
is an analog interface for "traditional cti" then our card is
overkill and likely will cost too much for your application.
However, there's also something to be said for being supported *now*, and
being the cheapest readily-available option. ;) I know that Lucent-based
Winmodems are supported (and cheap!), but trying to find one is a big pain
in the butt. ;)

Agreed. Where do we find these modems anyway? I haven't found any supplier
in the netherlands that can provide me with such a modem. :-(
I would like to put together a business pbx that couls support multiple
incoming co lines locally and also incoming calls from our satalite offices via
voip. I would greatly appreciate it if someone with more experiance with this
type of system could tell me what you think would be involved in putting such a
system together. Very interested in what hardware would be needed. I have been
looking into the LineJack and PhoneJack products.
Some features that we would like to implement are
call parking or queing
call tranfere
call hold
music on hold
voice mail
voip (we use Cisco routers that support voip)

They technically are not yet supported, but there's enough code that we
could support a single modem. I'm having trouble getting the latest code
to do useful things with my winmodem though, and it complains of RAM
errors.
I would like to put together a business pbx that couls support
multiple incoming co lines locally and also incoming calls from our
satalite offices via voip.
This is exactly the environment that Asterisk is designed to work with.
We're still a bit slim on the hardware we support for brininging in real
phone lines, however, and the VoIP is currently Asterisk specific.

The PhoneJack is currently supported. The LineJack could be supported,
but I do not have a unit to work with, even though quicknet claimed they
would send me one.
I have been promised a unit from SpellCaster (their ISDN, basic rate
card), and with any luck will have that as a way of bringing in lines.
Quote:
call parking or queing
Call parking is supported already. Queuing could probably be done in a
similar fashion, but there is no timetable for that feature, and I would
want it to be discussed on the list in greater detail.
Quote:
call tranfere
Transfer is supported.
Quote:
call hold
Hold can be accomplished by parking the call and picking it up later.
Quote:
music on hold
Currently not supported.
Quote:
voice mail
Supported already with Asterisk.

voip (we use Cisco routers that support voip)
Asterisk uses its own powerful and fast VoIP implementation. There has
been some discussion for adding OpenH323 as well (which presumably is what
the Cisco's are using), but no one has contributed code yet.

I'm currently in the process of getting OpenH323's test program to work
with our existing closed-source VoIP gateway (it seems to be an
interoperability issue).
The thing (supposedly) works with NetMeeting, and so does OpenH323, thus
it can't be _that_ bad. (Famous last words, I know.)
When that works, I'll have to convince OpenH323 to give me an interface
to the audio data. I hate C++. ;-)

There is no such thing as overkill.
