Full Duplex
We've had an issue since we went live nearly two years ago on Asterisk
where people complain about not being able to talk while someone else is
talking. I had assumed for a very long time this was because of the
phones we went live with (Grandstream GXP-2000's) and for the longest
time I believed this was a speakerphone problem only.
Last week during budgets, a request to buy new

Voice activity detection
Hey sorry to hijack this thread, but I just remembered a request I
wanted to make to the speex devs. I tried using the activity
detector, but I just couldn't get it working well. I ended up using
my own, where I think it just considered voice on if it passed a
certain threshold (I know, pretty primitive). I also tried one that
checked for a signal, like if the strongest frequency

Hello, I just bought a TE121 T1/E1 card, and now trying to install it on a

Sound quality issue
Greetings everyone,
I've been having some strange issues with my Asterisk box and some snom
phones.
In some cases, when I talk, the sound in the other end is cut off, I
stop earing the background noise - looks like a walkie-talkie. I've
tried this between phones in the same network and in all but one this
happens. The one where it doesn't happen is the one connected directly
to the

Re: 911 and lawsuits and redundancy
Hi,
Most companies we work with, have 'designated' crisis management teams.
These vary from the insignificant crisis', through to life-threatening
crisis'. There is always an assigned emergency services contact, whose
job it is in an emergency, to maintain communication with the emergency
services.
One of our corporate functions is crisis management - so we have to

Voice activity detection
This must be a simple issue, but I cannot figure it out.
I want to use VAD, but I don't know how to check if the actual frame has
voice in it or not.
So, in my code, I do:
int tmp = 1;
speex_preprocess_ctl(preprocess_state, SPEEX_PREPROCESS_SET_VAD, &tmp);
speex_preprocess_ctl(preprocess_state, SPEEX_PREPROCESS_SET_DENOISE,
&tmp);
then later, for each frame

speex over radio and homemade hardware
I've been given the task to hunt down a codec that out solar car team
can use to transmit and receive data over a radio link between a chase
car and the solar car its self. As of now I do not know the exact
specifications of the internal hardware of the car, what I do know is
they are looking at transmitting across a 2400baud connection, the unit
in the car is homemade from our labs here.

Re: 911 and lawsuits and redundancy
Well, to do an upgrade on a traditional system you have the same issues, perhaps even worse as everything is physically wired to one system. To develop for production you must have a dev environment, a beta test and a scheduled release right?

(Classical) Request for Standardization of expanded TAGS
A month or two ago I sent an email to this list proposing to expand
the list of "standard" tags for Ogg Vorbis. No tag would be required,
but if you wanted to encode certain types of information about a file,
you could use a standard tag.
I went through the whole discussion, and revised my proposal in light
of all the comments from everyone. Here is the updated proposal.
