    Re: stuff to do on Baud Day

    I'm bringing an ATA, some modems, a couple radios, and a couple TNCs (packet modems) over to the local makerspace, along with the Baud Day music playlist, and we're gonna get that shit all connected one way or another. Unfortunately, since the makerspace moved, nobody has set up
    the PBX/voip stuff again. So, we'll have to bring our own and figure out what to do as far as service goes. Maybe we'll do just sip to sip if we can't get a POTS service going.

    Hi phigan, do you know how to get modems to connect on ATA via VOIP?

    I have asterisk server with 2 extensions that can call each other but modems will not connect.
    2 USR 56k modems. I don't understand why they can't complete the handshake.


    Maybe some of the BBSes with dialups on ATAs would be open to
    additionally have a SIP number/address :).

    Oh ya, and the radios can connect to eachother at 1200 baud.

    Hi, good luck with your project! I recently started a project to create intranet lines for modems and telephones using a PBX server. I've been able to successfully connect modems and achieve speeds of 33600 kbps and higher. However, I haven't received any requests, and it seems like people aren't interested in using their modems over SIP. But it's not a big deal-my project is up and running and works perfectly for our group, at least.

    I actually inquired about it in your fido phonenet echo but didn't get a response.

    I currently have a POTS phone line via the local provider. It used to be
    a regular copper wire system but they have long converted over to
    providing phone service via the same cable that brings TV and internet
    into the house. The inbound cable hooks up to a "phone modem" (provided)
    and that connects to the copper wire system inside the house.

    I have noticed a difference in call quality. I used to be able to
    connect and get 33.6 connections. Now, outbound, I can usually get up to
    14.4k and have it work. Inbound calls sometimes work OK at 9600, but the
    calls are not reliable any more.

    If I use your service over the same internet connection I currently have
    (that brings in my current phone service), would I be able to expect
    better call reliability and maybe even faster connections, or should I
    expect it to work about the same as what I currently have?

    I'm sorry if you asked the question on the FidoNET forum in Fr+En and didn't get a response. I must have missed it, and my colleagues did too-I'm sorry.

    First, do you live in Canada or the USA? Next, are you interested in having your number accessible from any phone, or do you want it to be an extension on PhoneNET v2.0 that would only be accessible from another person on PhoneNET? Because for now, we don't have many clients on PhoneNET; BBS SysOps seem to be ignoring this service.

    If you want a phone number that is accessible by regular users with a number, I need to know which city you would like to have the extension in or transfer a number to. And I'd like to know how many lines you want on this phone number. For my BBS, I have a number with 5 lines. It's not the same price.

    This is the first part to understand what you really need. For the second part, based on what you tell me, we'll create an account on the PBX and configure your modem. You can test it and see if it works as you want, or if you don't like it. If you don't like it, we will have done the tests and the necessary configuration, and we'll know if it works properly from your location. I know it works, but with delays and pings varying from one place to another, you never know where it will end up. So, to see how it performs, we need to try it.

    If you want to test, you can try to connect to my modem with the number that is in my signature at the bottom of my message. The part of my PBX with my modems is 100% set up with the right protocols and configurations. It's not a bad idea to test before and after. And if you want to use my service, you should normally get the best results. That's because you will have a direct connection from one modem to another.

    For most people at home, because they are passing through multiple levels of audio compression, they can't expect excellent results. The phone companies want to make as much money as possible. So, they compress the audio as much as they can to reduce memory and CPU usage to the minimum.

    Whereas I prioritize audio quality.

    Of course, if your neighbor uses phone company XYZ and tries to connect to your modem through them, and you are on my system, it's normal that there won't be crazy performance and stability. Because from XYZ's side to my PBX server, I have no control over them.

    Does that answer your question? If you want us to test and go further, just send me a private message.

    Hi, good luck with your project! I recently started a project to create intranet lines for modems and telephones using a PBX server.

    I was a telecom manager in a former life, when desk phones, US call
    centers and fax ruled the office. I'm glad to see people still playing
    with voice technology. I recently found a Yealink SIP phone for $10 at
    my local tech thrift store and used it as an excuse to play with SIP.
    Set up a line through voip.ms and have been using it for work calls
    from my home office.

    My wife works from home 2 days a week and we have spotty cell coverage,
    so she can use the land line when she needs to. I'm planning on getting
    rid of Comcast in favor of AT&T fiber, which means the land line goes
    away. I'm tempted to throw up an Asterix container in my homelab and
    run 2 SIP trunks into it.

    Have fun. But I should tell you that Asterisk with SIP is quite a world of its own. I had to install it many times before finding the right setup.

    I'm running a couple of sites running their phones off of what looks
    like Asterisk with a nice web front-end - even though it's not my job to support them. Once you do telecom professionally, you never get to stop.

    Hi rmurray,

    How did you connect your modems on the infrastructure side?

    I can't get mine to connect via my Asterisk server.

    I have a very basic setup:
    2 extensions (pjsip), and my sip settings are using ulaw, alaw codec.
    I think my ata spa122 is set to use G711a codec, but the handshake doesn't complete.

    are you using an ATA?

    Are you using simple extensions with asterisk or something additional?

    I thought in order to go above 33k6 one end of the connection had to be using ISDN? Possibly my friend's off-hand comment in the 90s wasn't 100% accurate, or possibly that's true but only due to high frequency attenuation on real analogue lines?

    Interested to hear your thoughts on this :)

    For now, with the tests I've been able to conduct and the places where I've set up this system, I can't give you a definitive answer. I only know that I've managed to exceed it. As for the rest, more testing and installation would be needed to document the results. But switching from copper to SIP has certainly complicated modem communications, as it wasn't a priority for them.
