Codec Negotiation Does not seem to work as e xpected ?? Help Please !!
Steve,
My Problem is not a problem, with the codec negotiation between end points.
But when asterisk does it with canreinvite=no, * do not do it right. I
replied with a lengthy discussion about my findings here, This behavior can
be reproduced. But '*' do not seem to do the negotiation correctly.

FW: Sip codec preferences
Did anyone have a way to make codec negotiation work with Asterisk?
This is something I would love to have working as well.
I won't need PSTN -> G729 mixing. Just SIP -> SIP using G729 for calling remote offices via VPN, but everything else use G711.

SIP codec negotiation / manipulation
We're having an odd issue with codec negotiation from one of our SIP providers. Here's the basic situation.
We receive an invite from them advertising support for G711, G729, and G723. In our response, we send back that we support G711 and G729. In about half the cases, this results in no problems, with audio being encoded with G711. The other half of the time, they send us a second

Codec Negotiation Does not seem to work as expected ?? Help Please !!
Hello,
I have been trying to get my coders to work without a conversion. I have
read all the available asterisk documentation and support groups without
any luck. Here is my issue. (Please feel free to ask questions if you do
not understand what I am talking about.)
I am using Cisco ATA-186 set to g729 codec. (But it will switch to g711 if
sip-server request g711)

Codec control
How can i control the codec for the calls. For example I have 3 SIP
phones registered to asterisk
The firs two are in the local area network (behind nat)- I want to use
g711 between them and to connect directly (canreinvite=yes)
and the third is in internet - want all calls to it and from it to use
g729 and media to go through asterisk.
So if Phone 1 calls Phone 2 the codec to be g711, but when

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)

No audio after a reinvite changing codec

Codec Conversion
Hello,
Is there an utility for asterisk for codec conversion? I tried google but i haven' got anything.
I am trying to initiate a call with G711 codec to asterisk and i would like asterisk to call a gateway with an g729 codec, therefore making a codec conversion from g711 to g729. I know chan_oh323 does it by specifying the OUT_CODEC variable, but chan_h323 does not. And i was wondering is

Fax passthrough howto codec upspeed
Hello everybody,
Just was wondering if somebody can help for G711 fax passthrough w/ asterisk.
The issue I have is regarding codec upspeed when the call is already connected using G729 for example. The setup is fax---ATA---asterisk---Cisco---fax
When codec upspeed should happen, ATA or Cisco will send a G711 reINVITE causing the codec to be switched over, but asterisk does NOT

3way calling / codec problem
I'm having problems with conference calls (3-way) when I have my codec
forced to g729 in sip.conf.
I'm using Grandstream 2000s.
If enable both g711 and g729 then 3 way calling and transfers work.
I'm not sure why this would matter?
Here's the error:
Oct 13 13:54:45 NOTICE[31184] chan_sip.c: No compatible codecs!
Any help is greatly appreciated!

Best Codec
We are evaluating starting a small VoIP consumer based platform.
What is the best codec to use with customers using primarily DSL as
internet connectivity?
I know that g729 is the king-all, but I want to know what the rest of
the professional are using out there. g729 has a cost involved, so does
the cost really offset the performance? Or is it better to go with g711
to start off?

Codec problem from SIP to H323
Hello.
I have a codec problem to send calls from a SIP device to a H323 gateway.
First I'll explain the scenario:
- Asterisk 1.2.1
- The SIP phone can use any codec I want.
- The H323 gateway can only use g729 (cause it's not under my
administration)
- SIP phone has g729 configured, so my asterisk doesn't need to "transcode"
(I don't have licences for g729)

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?

Setting codec on originating (calling) channel with chan_pjsip (SIP_CODEC_INBOUND equivalent)
Hello Michael,
you are referring to the following behavior - did I get it correctly?:
outbound broken: asterisk offers g722 / g711 to provider (callee),
callee answers g711. Asterisk now transcodes between caller and callee
(g722 <-> g711).
inbound works: call from provider: g711 -> asterisk drops g722 and
passes g711 to internal callee -> no transcoding.
As far as I know,
