Can't get any data through the USB modem #139
Comments
Hi b'RING\r\n' I have now purchased a US Robotics Model 5637 and when I make an inbound call I get the following output: b'DATE=1203\r\n'

Hi @dimitriscr. I'm sorry you're having problems. Thanks for the DEBUG log; your modem initialization looks OK. Two possible issues come to mind:
The fact that there are no "RING" entries in your DEBUG log implies that the modem is not actually receiving any signals from the phone system. The modem should be connected jack that a phone could use. To test, you should be able to connect a phone in place of the modem to assert that the cable and jack are functional (e.g., assert a dial tone). I hope this helps. Let me know your progress. |
My Modem is connected by a splitter to the same line as my landline that works properly. Caller_ID is slightly more of a wildcard. There is no mention of it anywhere on my providers plan or website. Since there is no way for me to pay for the service i just assumed i had it by default. Since you said that the Modem seamed to work properly, i guess that leaves called_ID as the only thing left. I'll try to see if there is a way for me to confirm if I do have it or not. TL:DR it's not the modem and my line probably doesn't have caller_ID enabled Thx for your help |
@Strider2525, thanks for your comment. It would appear that the "Zoom 56k USB Modem Series 1063" does not appear to be a "voice modem". I only found reference to "faxmodem" in the manual. It be clear, your callattendant is now working correctly with the USR modem, correct? The modems I've tested are in this thread: https://groups.io/g/callattendant/topic/78477504#108 @dimitriscr What is the model number of your Zoom modem? I'm still suspicious about the lack of RING indications (like those in @Strider2525's comment). Also, I've used a splitter successfully before, so that by itself should not be an issue. Do the modem lights/LEDs give any indication of an incoming call? |
@dimitriscr That's one of the modems that I have successfully tested with. I will hook it up again today to verify what the correct behavior should look like. Meanwhile, one last thing to try is to power cycle the modem: disconnect/reconnect the USB modem from the PI and then restart the call attendant. |
Hi Bruce It is the correct Zoom modem, the series is 1063 and the model is 3095, picture attached I have checked on the Zoom, when an inbound call comes in only the DATA light flashes, the OH does not come on at all |
@Strider2525, thanks for the clarification. Here's a picture of my Zoom 3095...not too much in common. |
@emxsys I have the square one too, could that be the issue? |
@emxsys it looks like yours is a different model, a 3095A, as well as its shape |
@Strider2525 I concur. My modem box is identical to the picture posted by @dimitriscr. Unfortunately, the "A" model doesn't appear to be a discriminator when ordering. |
@dimitriscr Following is my debug log when using a 3095A modem. The modem initialization looks identical to yours, as does the active profile's modem registers. Do you have a "distinctive ring" enabled on your phone? See +VDR - Distinctive Ring in this document: http://www.zoomtel.com/documentation/dial_up/3095F_ATcommands.pdf. Could that be a factor? If your familiar with minicom or another terminal program, then you can experiment with the modem AT commands needed to get the RING notification to work. My modem init with 3095A
This is the debug log I get when a call comes in:
|
@dimitriscr @Strider2525, per table 3.5 in http://www.zoomtel.com/documentation/dial_up/3095F_ATcommands.pdf:
Here's something to look into with a terminal program: +GCI - Country of InstallationThis extended syntax command selects and indicates the country of installation for the Syntax
Reporting Current or Selected Values
|
Alright, sorry for the wait, it took me a bit to understand how minicom worked. My GCI is B5 which i assume is not France and my VDR is 0,0 which I assume means it false. Is there a way to change the GCI to france or is it build into the modem? Is it what is preventing my modem from receiving calls? Edit: B5 is the US according to this: https://opengear.zendesk.com/hc/en-us/articles/216371103-ACM5003-M-Modem-Country-Code-List |
Try: +GCI=3D
B5 (USA) is the factory default.
|
Alright, I changed it, I checked it again and it has indeed changed to 3D, but still no luck with getting it to detect a ring. |
Rats! I was hopeful that was it. |
It's definitely worth trying. It's a data point either way. |
Great news! I'll consider how to factor this into the codebase or configuration. Re: CID. You will need to enable it. I think this is the command: AT+VCID=1 |
To be clear you would need to enable VCID when testing in minicom. The callattendant enables it in the modem initialization...you can see it in your debug log. |
Alright, I still don't seam to be able to get a number, I will keep reading that documentation you send me and i'll see if I can fix it tomorrow. Thx again for your help |
@emxsys , @dimitriscr I'm having a similar issue of never seeing a RING, but none of the above ideas have helped. I tried explicitly setting GCI=B5 and VDR=1,1 and the modem init looks fine but then no ring ever shows up. Any other ideas? |
Hello, I have set up my callattendant like described in the setup guide but it doesn't seem to be able to see any phone calls made to the landline I have. I am in France and I'm using the "Zoom 56k Dial-up V.92 External USB Modem". Callattendant seems to detect the modem, but I can't tell if the following output means that it is working or not.
I don't know what the problem could be, it might even just be the modem that doesn't work (I bought it used). Sadly I don't know enough about USB modems to interpret the tests that it seems to be doing. Oh and the web interface works without any problems.
Thx in advance for your help.
