[gentoo-user] telephony
hi there, i'm looking for suggestions and guidance. I have a vps host with gentoo on it, i dont think the vps is stable enough to ensure a good quality of service, but it could just need an upgrade, no big deal. I need a phone and the way i decided to go was to get a connection to the internet and use voip or similar services. I've looked into several ideas, but the last one that remains a good 'deal' is to set it all up myself, for free (but lots of work)! I'm thinking on setting up asterisk, but having read about it in the past, i know as soon as i set it up it will take more of my time than my girlfriend ever dreamed of! It seems extremely difficult to setup, specially for a newbie, I'm wondering if you guys know of a few good guides (that you have experience with, i can google too) for this and if you had any suggestion, pointers, starters mostly... I've read those, but I'm sure there are a lot of surprises not covered by these... http://www.voip-info.org/wiki-Asterisk+Linux+Gentoo http://www.gentoo-wiki.info/Asterisk Thanks for any help! -- When Earth was the only inhabited planet in the Galaxy, it was a primitive place, militarily speaking.

Free help doesn't exist, really -- there's just too much money to be made replacing proprietary telco hardware for folks to enjoy educing that aha! moment. All would tell you, at your hourly rate, choosing to roll your own asterisk install on Gentoo is probably the most expensive option available to you. Anyway, it can be done. #gentoo-voip are helpful folks, but unless you have a real reason to know asterisk, really, don't bother... it's huge PITA for just getting a phone. Even if you do decide to kill that gnat with a sledgehammer, you're better off with Trixbox, astlinux or something you can pretty much expect some help with. (So I hear.) If all you want is to use a SIP trunk, my local telco monopoly, for example, will rent me a box to plug a phone into for a fixed monthly fee and unlimited calling. Or, you can probably get any Dahdi compat fxs card and plug a phone into your gentoo box. Or just get a SIP phone... plug into your router. Basically, there are so many options, it's bewildering. From my (limited) experience with it, I'd say that Asterisk is really more of a place to create telco appliances from computers, not an application you run with other things as an afterthought, just because you can. But, then again, you already run Gentoo, so you are familiar with needless self-inflicted pain as a pastime. Asterisk may be just for you, too! ;-) Cheers, -- |\ /|| | ~ ~ | \/ ||---| `|` ? ||ichael | |iggins\^ / michael.higgins[at]evolone[dot]org

Re: [gentoo-user] telephony
Well i've had several projects ideas in the past that would have used asterisk in different ways. So, the reason to get it installed for my personal 1-line use is really a first step in understanding asterisk's basics and since I will probably work and tweak it every day for a certain period of time, this would be an awesome learning experience. I dont have a GF, yet, and the lady that might fill the position (soon?) wont have a word to say about that. haha But i clearly hear what you mean about the waste, I'm with you on this, but i also see it as an investment! Thanks a lot though, you brought some important points to consider!

Hey Stroller, nice to see a friend in a similar situation as mine! I'm sure that having the hardware already, you probably made a lot of tests in the past... can you share some of your experience? and also, i wonder, why did you let the project down? was it because of lack of motivation (ie other priorities) or because the difficulties you found?

Re: [gentoo-user] telephony
Your welcome, also I seem to remember there being a caveat to running asterisk in a vserver (if your host uses that technology) but its not coming to mind. Maybe when I'm home infront of a real computer I can find it. Also I really liked the voiper soft phone, its not in the tree but might be woth a look.

I've actually got a really expensive (or it was when I bought it!)
Cisco
phone and an X100 POTS card sitting here, as I've been meaning to
get round
to implementing Asterisk for about 4 years now! Perhaps this thread
will
give me a little bit of a kick up the arse.
nice to see a friend in a similar situation as mine! I'm sure that
having the hardware already, you probably made a lot of tests in the
past... can you share some of your experience? and also, i wonder,
why did you let the project down? was it because of lack of motivation
(ie other priorities) or because the difficulties you found
I've fixed your quoting. If someone replies at the bottom of your
post, please do not then reply at the top.
No, I'm afraid I never made any tests or anything like that. I use
vgetty here at present, and have been for 5 years - that is just a
service that uses a conventional old voicemodem as an answerphone. It
saves the recordings as wav-like files and can then (optionally) calls
another program with /the/path/to/the/recording as a parameter, so I
use a Bash script to convert the wav to an MP3 and email it to myself.
I have found an emailing-answerphone very useful, but at some point
since I read about Asterisk and thought that a whole & complete VoIP
"solution" was just much "cooler" and elegant & stuff. I think of
redirecting callers to different answerphone messages based on CLID
for instance ("I don't want your shitty double-glazing") or telling
the phone not to ring before 9am if it's a business call. To be
realistic, these aren't very good arguments - vgetty might be able to
perform the first task I gave as an example (I don't know), and the
latter case wouldn't really suit my lifestyle (sometimes I'm up at
8:30 and want to answer the call; the list of exclusions for important
customers would be complicated to manage; I'm better off rolling over
in bed & ignoring unwanted calls as I do now ;). So we get back to the
"cool" factor ("I can make free VoIP calls to the USA" even though I
know no-one in the USA) and that at least Asterisk could look up phone
numbers in an LDAP directory so I can ignore customers who call when
their work is overdue. :P
So anyway, a while back, in a fit of enthusiasm when I had plenty of
cash slushing about I grabbed the hardware from online vendors, but it
has sat here idle ever since. :(
I've been meaning for sometime to rebuild my server so that I'd have
a system to run Asterisk on, but just lots of other stuff has gotten
in the way. It would be a long & boring story to explain all the
circumstances that have coincided against me, but suffice to say I'm
not the best-organised person at the best of times.
If you want Asterisk to answer your conventional POTS phone line then
you can use an X100P card which you can buy for c £17. AIUI this is
basically a modem based on a certain chipset that Digium have written
drivers for. At one time Digium sold this hardware at quite a premium,
but people realised that other models would work just as well, and
Asterisk (who are sponsored by / part of Digium) has been very fair
about supporting these "clones" in the codebase. They're obviously not
supported if you buy an official support package, and IIRC I have seen
posters on the Asterisk mailing list being snobby and refusing to help
posters using the clones because it's "not supporting the developers".
I don't know how well the X100P works, or if there are any "gotyas" to
look out for, but I'm pretty sure plenty of people are using them. A
couple of friends of mine (who I considered going into IT consulting
with) implemented Asterisk after I mentioned it to them and I'm sure
they've used the X100P; I think those lads have deployed Asterisk for
customers since.
As far as phones are concerned, the Cisco 7960G was the phone to have
when I bought mine. I think the 7961 had just been released, or
something, and the 7960 was old stock. I paid £200 for mine, but now I
see you can pick up decent-looking ones on eBay for £40 or £50. :o
This phone has handsfree and a big screen on which you can display
several lines of information (caller ID, "line 2 on hold", phonebook
listings) and buttons to the side of the screen so that you can put
someone on hold & pick up another line and do all that sort of stuff.
Although the 7960 is no longer a current model it seems to be
supported with fairly recent firmware, and later phones in Cisco's
79xx series seem very similar without appearing to add much (256
shades of greyscale instead of plain B&W text, or colour / touch
screens in the executive models).
If you use the X100P to answer your current landline then you're not
limited to that. A PBX is intended for business use, and a business
might want to have 8 or 30 lines coming in via ISDN

This may be true, but I believe it's more because the cards, as every one will tell you straight up (unless they are selling you the card, of course) are of poor quality and design. > I don't know how well the X100P works, or > if there are any "gotyas" to look out for, but I'm pretty sure plenty > of people are using them. Yep. There are driver issues, voltage/signalling problems... and in the end, even if working, they won't sound good. There's a reason they are, like, $10 on Ebay. Basically, they are decent winmodems (if such a thing is possible)... that they can be used for telephony is a fluke. > A couple of friends of mine (who I > considered going into IT consulting with) implemented Asterisk after > I mentioned it to them and I'm sure they've used the X100P; I think > those lads have deployed Asterisk for customers since. Yep. Definitely a way to get your hands dirty. By the time you figure out what you need to know to get a decent answering machine with your new toy, you can go buy real hardware and make telephony appliances. Meanwhile, anyone likely to be of any real help while you experiment, is doing just that, and has no interest in watching/helping you suffer, from what I've gathered. My time figuring out the first glitch between my card and the (sort of) supporting driver would have been saved/paid for by buying a real FXO/FXS card initially. I didn't do that, but you, or the OP, still can. And, finally, if I want to ever *use* this experiment in the real world, I'll have to replace the X100p with a decent sounding device anyway.

Hi Michael, Many thanks for your comments. How much is one looking at for a "real" FXO/FXS card? I'm not sure the difference between FXO & FXS - just want something to "convert" my home phone line for use with Asterisk or similar. Don't bother giving me model numbers or anything like that - I can do my own research & I'm sure the situation will have changed by the time I get around to deploying. Just interested in a labb-park figure, as the little Irish girl said. Stroller.

Just interested in a labb-park figure, as the > little Irish girl said. You seem to want to know the difference, FXO vs FXS. If I got this wrong, just delete it. FXS is meant to interface to a telephone set, so it gives talk battery and (as needed) ringing current. FXO is meant to interface to a line from a telco switch, so it accepts battery (if the circuit it's hooked up to doesn't give talk battery, you have no circuit) and expects to be rung into, so it detects ringing battery. Most of the time, both FXO's and FXS's offer options to operate in loop start (regular POTS) or ground start mode. Write me if you need more on that last. Options like reverse battery aren't usually offered in FXO/FXS cards. You usually have to give a FXS card your own source of ringing battery, not FXO, because an FXO is expecting to have ringing battery sent to it (from the telco switch it's connected to) to begin with. -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAknyJcMACgkQz62J6PPcoOkDCQCgkZDtKOBXKvU+QT0Byyg4UWCN YvMAnRwS2MKrVjpGV23kscQzbWfQwMPV =n5oK -END PGP SIGNATURE-

This brought an idea in my mind... the phone lines in our houses here in Quebec,Canada are set so the line comes into the house at one point (called dmark i think) then it is spread around. if there is no service, then there is no dialtone, if one phone is used, then all phones can hear the conversation if picked up. normal stuff. but what if i were to setup a pc to work with asterisk and somehow plugged a FXS (i guess?) card to any phone jack in the house. then any normal phone would be networked to that FXS card and anything done on them will go through the PC (the pc will actually take care of sending a dialtone, etc...) am i correct, is this possible (to use the existing POTS infrastructure)? Thanks

I'm afraid I don't completely understand how you'd do that. An FXS card is used when you want to interface between on kind of communications and another. Usually you have, at one end, a regular 2 wire line, a "POTS" line, but you'd only need this FXS card if the other size of the circuit differs: maybe it's a 4 wire circuit, maybe it's a DS0 channel of a T1, I don't know if folks are still using SF-based circuitry anymore (the ability to fake out the signalling is very well publicized nowadays). You comment about putting an FXS card on your house wiring isn't clear to me, but the electrical and communications effect would be similar to attaching an extra telephone set to your house wiring, I think. I could make more sense if YOU could make more sense, and tell me why you'd be using that FXS card (what sort of signalling conversion are you effecting?) One example might be to take your two wire house POTS line and remote it to a different state, like originating in Michigan, and adding a remote to New Mexico. You can't move a 2 wire line anywhere near that far, so you'd need to convert the signal to some format more well adapted to long distance travel. Again, it would be exactly as if you had added a new phone set to your house wiring. You'd hear if someone were listening this way, it wouldn't be silent. Creating a good tap of a 2 wire line would be possible, but not that easily, and it would have to be listening only, no ability to break into the conversation. > > Thanks > -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAknzeY8ACgkQz62J6PPcoOld6ACgkn1hjAV8LYyukPM2OVuIFfwQ zFEAn1e2kQrlIbR9gN7AS8MAiOZXHWTv =ux0T -END PGP SIGNATURE-
Re: [gentoo-user] telephony
Sorry for top posting my bb is dumb about that. The answer to your question is yes, you can uses your current pots lines. You want your outside line to be fxo and lines connecting to your standard phones to be fxs. The digium wildcard supports 4 pots and you can buy them with a different mix of fxo/fxs, they are simple removable modules. Don't waste your time with a x100p card, they suck and will be more of a waste of time then they are worth.

I use it with the speex codec and voice quality is really good. It was even usable when those middle east cables were cut some time ago, and latency was over 1 second for me. Asterisk in portage hasn't been updated in ages. It's still at version 1.2, while 1.4 and 1.6 have been available since dec 2006 and jan 2008 respectively. There is a VoIP overlay where you can get newer ebuilds. Actually now that I think about it, it might be better to use an older version as most documentation online refers to the older ones. One interesting feature of v1.6 (if your asterisk box is not in a remote location) is chan_mobile. It can hook up asterisk via bluetooth to a cell phone using the handsfree profile, and then use the phone as a PSTN trunk. It works with my phone, but I don't think anyone uses this in a production environment. I would recommend reading chapters 4,5,6 of "The Future of Telephony" book [1] at least three times before starting. The new edition of the book refers to Asterisk ver1.4. It's not that hard especially if your goal is to learn. Otherwise just buy an appliance like [2] for a couple of hundred bucks, click around in its GUI config and be done with it.
