[Linphone-users] AEC, and Debian Stable

[Nikhil Nair]

Hi,

I'm new to Linphone, and have a couple of general questions.  I use 
Debian Linux, and, as I'm totally blind, I use a text-based terminal 
rather than a GUI.

I'm after a tty-based softphone which will do acoustic echo cancellation 
(so I can use speakers and a reasonably powerful microphone, rather than 
headphones etc.), and which is able to send DTMF digits.  It seems that 
the Asterisk console doesn't satisfy these two requirements, much to my 
surprise (perhaps it's more for testing than for serious use); am I right 
in believing that Linphonec does satisfy both?

The current stable release of Debian includes linphone-nox 1.5.1.  I've 
tried to run linphonec from an ssh session, but get a series of errors: 
first I get a warning that my machine seems to be on an IPV6 network 
(actually, it isn't...); strangely, when I tried to capture the output 
with 'linphonec &>/tmp/linphonec.out' this warning disappeared.

I then get a series of errors about certain devices not being found 
(details included below), after which linphonec segfaults.

As far as the devices are concerned, I'm a bit puzzled; I'm using udev, 
which is standard on Debian, but I didn't want it to do any video 
anyway...

Details of errors:

Any suggestions much appreciated!
