A USB handset is basically a sound device (and not a great one, usually)
along with a small keyboard. Linux will usually easily identify the
sound device and you can use the phone as chan_{oss,alsa,console}.
Using the keyboard in it may be trickier.
Do any of the above support cancelling acustic echo? Is it actually
needed in this case?

Tzafrir,
Thanks for the reply. Acusitic echo cancel may not be needed as this
will not be used in a noisy work place, only in possibly quieter home
environments. There will also be no need for speaker phone operation.
Enabling the keypad is definitely the tricky part. I am trying to avoid
loading a soft phone since I don't want to have to instruct the users on
how to use one (mostly NON-technical types). If the set looks and feels
like a phone they will be OK on their own. I guess I may have to go
with a decent, hopefully inexpensive, basic IP desk phone. |

Iirc, there used to be such an adaptor in the digium dev kit years ago.
Maybe somebody here remembers what it was exactly ?

I have a need for a USB handset that I can use with an Asterisk
server. This will be on the server itself and an extension on that
server, most likely the only extension. The handset needs the ability
to generate its own on hook/off hook and DTMF so that I would not need
to load a soft phone. I will eventually be needing many of these so
if the set up requires a lot of hacking to the phone it "may" not be
feasible. Having said that any suggestions will be appreciated. I
know I could use an ATA and a PSTN Phone from wally world, but this
will not fit the project or the need.
Thanks,
JohnM

I doubt that chan_oss/chan_alsa directly support echo cancelling.
However depending on exactly how you are using the inputs and outputs on
a sound card, you could very well need echo cancellation.
90% of the time, echo is generated at the junction between a channel
that separates received and transmitted audio and one that receives and
transmits on the same physical channel - an analogue line is the usual
culprit. If your link to the PSTN is via an E1/T1 channel, chances are
good that you'll still have an analogue line at the end of your call so
the echo moves beyond your direct control. That's the normal scenario
for requiring echo cancellation.
The remaining 10% of the time, echo is generated by sound "leaking" from
a speak to a microphone on a handset or by some other means. This is
where echo cancellation /may/ be required for a chan_oss/chan_alsa
channel. If your headset mic is too sensitive and the volume on the
headset speakers is a little too loud, all of a sudden you've got echo.

I had a little success with a cheap USB 'phone' (From Tesco in the UK)
which was a Yealink device. Linux has a driver for the keypad on it which
makes it work just like a regular keyboard (limited number of keys,
obviously!), but the issue is still that you'd need a program of some
sorts to take the keypad input and translate it to an asterisk console
command dial, if using it as a console phone.
I did use it successfully some time back with idefisk, although idefisk
didn't have a keyboard equivalent of 'hang up' at the time (zoiper might
have now though). The down-side was that you needed to put the mouse over
the idefisk application so it had keyboard input focus )-:
Oh for a command-line IAX client, but it's something I just don't have
time to put together myself.

In the mean time, idefisk (now called zoiper) has support for the
yealink chipset phones on windows, (no need to focus), but he is looking
for a solution without softphone.
I'm unsure if they have an SDK for linux, chances are bigger that the
intel HID standard based chipsets might have linux drivers that support
the hangup buttons etc too. (as those dont exist on a normal keyboard)

Thanks for the replies.
I wonder if I could use the Yealink phone and write a connector to
Asterisk with the IAX client on Sourceforge and make the handset look
like an iaxphone? Or maybe there is some other easier solution? All I
need is to have the ability to go
off hook/on hook, pass DTMF, and voice obviously

You can't have a USB handset without a soft phone. You can get some
which automatically run the phone software when plugged in, but that
only works in Windows.

Asterisk (chan_alsa, chan_oss, chan_console) is a soft phone.

True, but deploying Asterisk to user PC's is not a particularly
attractive option.

Sorry, I didn't mean to imply that it was impossible to achieve the
same in Linux. Just that the existing commercial solutions are
targeting Windows.

John, I've done something similar. I had a simple commandline
IAX phone running on a low powered computer (actually an NSLU2 -
but it could be any linux machine), driving a USB audio card. I didn't
need
a keyboard, as it auto answered incoming calls.
If you are interested, contact me off list, and perhaps I can help.
Tim. |
