speex, ilbc and g729 codecs, GSM with IAX
Dears;
I do not know if any had experience in using speex or
ilbc with IAX and got good results, because I am
facing a problem with GSM.
I am facing a noise problem when I am using GSM with
IAX trunk as following:
IP Phone (G711) ---> Local Asterisk Box ---> IAX Trunk
using GSM codec ---> Remote Asterisk Box ---> Digium
Card (FXO) to terminate the call to the destination

Asterisk codec issue with sip / iax.
Hello,
I am doing some testing with my brother. We both have asterisk running
with a Cisco 7960 locally and it works great. Using SIP between the asterisk
boxes works great also.
If I use IAX to call his remote extension, it fails because the remote
asterisk server tries to use GSM to talk to the 7960. I end up going to
his voicemail, which works fine.
If he calls the same way it has the

channels can be transcoded from g711 to gsm at a time.

Is there a way to force a codec on an incoming sip uri call?
Hello,
I'd like to implement some public sip uri's that poeple can call into
and get an echo test. Is there a way to force a codec so that users
can test various codecs?
Something like:
echo-test at example.com (negotiates whatever codec, is there a way to
figure out what codec was negotiated and tell the user)
echo-test-g711 at example.com (forces g711)
echo-test-g729 at

FWD codecs?
Hi. There is not much info on the FWD site about this. What codecs do they use? When I try to connect with X-Lite, it works with GSM. When I try to call out with *, it wants G729. I have disallow=all and allow=gsm in the sip.conf. I end up getting errors:
Unable to find a path from G729A to GSM
Unable to find a path from GSM to G729A
What's up with that? I was able to make a call once

GSM codec is a good choice ???
Dear all, I have Asterisk 1.4 with SIP. I have a voicemail implemented
with GSM sound files.
The problem is I have IP phones Utopix HyperPhone 202 which support
only G.729a/u and G.723.1 high/low, but not GSM.
If I choose G.729A the "pass-throu" calls among users are OK, but
Asterisk can't transcode GSM to G.729A in voicemail calls.
My company doesn'y want to pay for a G.729

fax and codecs
Hello!
I'm try to implement a fax service using spandsp (0.0.2-pre10) and
NVFaxDetect (since I'm using a SIP channel).

The fax is detected by NVFaxDetect and than a macro is started.
The welltech use Alaw codec.

ADPCM codec and IAXy device
Hi All;
I need to buy one IAXy device, but I discovered that
it supports only g711 and ADPCM codec, so I was wonder
that it does not support g729 or GSM?!
Anyway, what is that ADPCM and how much it consumes
bandwitdh? Also, asterisk support such codec? What its
name in the configuration?
Any advise?

My G729 problem re-visited
Ok, I built a test system to duplicate my problem and provide myself
a platform that I can mess around with to try and break any features.
My problem is G729 pass-through from a gateway to a phone. I think
I even have transcoding working, which makes me more confused on
what's wrong with my pass-through. It must be a configuration issue.
The basics...

Explain "core show translation"
Hi,
I've read in http://www.voip-info.org/wiki/view/Asterisk+codecs but I still
have questions about "core show translation".
How are values replied by "core show translation" computed in the the first
place ?
I've got 2 machines using a 3GHz Intel CPU : 1 is a Xeon, 1 is a Pentium 4
(gathered with cat /proc/cpuinfo)
The Xeon machine is showing, for instance:

X-Lite Build 1059 problems
Does anyone have X-Lite build 1059 working fully with Asterisk?
The GSM Codec works very well now but we have problems when using G711
in that when I setup a ping between the two sites and then watch the
latency, it steadily increases and starts at about 150ms and goes up to
2500ms within about 20 seconds. I have not investigated fully but I
guess that its sending ever increasing size packets.

what can we do with lost voice packet on a congestioned VPN?
Hi to all
in a scenario where:
- the bandwith is shared with other traffic (HTTP,VPN,ecc)
- the PBX is on a remote VPN peer
- due to many reasons Qos is not usable
There is a IAX trunk between 2 Asterisk 1.4 i've tried different
codecs (ulaw,alaw,gsm) but the main problem still remain the same: too
many voice packet get lost.
The main problem is surely on the network, but the strange thing
