Hi all,

does anyone already made asterisk work with a Gazel 128 USB modem ?

I use a Debian sarge, asterisk 1.0.7 and isdn4linux drivers.

The modem is well recognized by the kernel, it is registered as hfc_usb0 but asterisk doesn't seem to see it...

I have configured modem.conf with driver=i4l but I don't know how to indicate that it is a
USB modem, not a serial one...

Please help me

if never heard of it, but since its hfc, maybe chan_misdn will accept it ?

[tonio]

I have also tried with mISDN but without success.

I launch the hfcsusb module with modprobe and the required arguments. The modem is recognized.

When I try to start asterisk with the chan_misdn module support, an error occurs, saying that chan_misdn initialization failed...

I don"t see what I am missing

Maybe a configuration problem in the modem.conf file (with i4l)

[zoa]

i dont think using i4l will do you any good.

How about buying some cheap fritz card and get your problems over with for sure ?

[tonio]

It's not a possible option for me (it"s for my job)

I finally suceed in using misdn with asterisk and my modem, everything looks to work...

Now, I need to make outgoing calls from a SIP client, using an ISDN line (with a special phone number). Do you know how to configure this in extensions.conf ?

Thanks.

dial zap/g1 should do the trick

(and then your device has to be configured to be in group 1 in zaptel too of course).

Otherwise use dial zap/1 and dial zap/2

Good luck,

Zoa.


Btw, could you post your configs + every step you did to get it working ? So that future people with the same problem can benefit from your experiences ?

(as i dont have such a card myself).

[tonio]

No problem for config files.

But I don't use zaptel hardware, it is a standard ISDN modem.

I have to use something like Dial(mISDN/....) but I'm not sure about parameters (and it's the same for misdn.conf)

Any idea?

can anyone tell if fritz USB based ISDN adapter works with Asterisk on linux
Thanks

[tonio]

I confirm that Gazel USB 128 modems work great with asterisk 1.2.1

Here is a little 'howto' about the subject.

Actually, it's only available in french but configuration parameters are illustrated, so even non-french users can understand the document.

english translation will come soon

[zoa]

the link is broken,

If you want we could translate it into english.

[tonio]

Sorry for the link, it was a redirection problem...

This is corrected

A little help for the translation would be appreciated, thanks for your proposal!
