asterisk users - Apr 2006 - transforming g729 files to wav files

Hello list,

is there any open-source software that recodes g729 sound files to wav 
sound files ?
The only way (at least) to do such transformation is with interactive 
form on:  http://www.asteriskguru.com/audio_conversion.php

The wiki also lists GX::Transcoder which looks like it can do g729 to
wav, though I've never tried it.  Here's a link:

Otherwise, you could probably rig up asterisk to transcode from g729
to another codec then record it to a file.

There's probably not more tools to do this since most people aren't
interested in going from the very lossy g729 codec to the non-lossy
wav format.

The resulting file is not going to sound any better and its going to 
take up more space. What is the reason you need a WAV file? Perhaps 
there is a more efficient way to do what you are trying to do.

Hi,
I wrote a script for making a gsm or wav file out of a text, i tried it 
first with text2speech from the festival package, and sox for converting 
it to a gsm file, that worked really well... and I can play it back with 
the Playback cmd.

But only in English, so I tried Mbrola with a German database... txt2pho 
creates the phonetic file out of the text I give it, mbrola makes a wav 
file out of it, which really works, and sox should transcode it again... 
but I just can't hear the file with the playback command :(

Why is that?

Hi ,

Here is my scenario :
I have an 7940 Cisco IP phone which can handle g711ulaw,g711alaw and 
g729 codecs itself. A Quintum A800 which configured to work with 
g711ulaw and a Cisco Gateway which configured to accept g729 codecs 
only. The Quintum gateway is local gateway which connected to PSTN for 
Local PSTN calls and Cisco Gateway is on the internet which can handle 
international Calls.
The problem is that when I configure my sip.conf like this on my asterisk :

[Cisco-7940]
type=friend
secret=<PRIVATE>
username=hamid
host=dynamic
disallow=all
allow=ulaw
alllow=g729

[quintum]
type=peer
context=from-pstn
host=xxx.xxx.xxx.xxx
callerid=From PSTN
disallow=all
allow=ulaw

[Cisco-Int]
type=peer
host=xxx.xxx.xxx.xxx
disallow=all
allow=g729

the preffered codec for cisco-7940 will be ulaw and it will work OK for 
calls to PSTN ( I mean quintum ). but when I want to call international 
numbers ( I mean Cisco-Int ) it will warn that there is no g729 to ulaw 
translation available and will disconnect the call ( Cause I don't have 
chan_g729.so on my asterisk ) however my own Cisco-7940 can handle g729 
codec itself and the asterisk should just passthrough ( make bridge ) to 
work with g729 codec. The same problem will happen for quintum if I 
change the allow=g729 position with allow=ulaw on cisco-7940 config. How 
can I solve this ?

BTW I check the same scenario with OpenSER and everythings working like 
a charm without any problem. I mean my PSTN calls go through the Quintum 
with ulaw codec and the international calls go through the Cisco with 
g729 as codec without any problem.

Hi,
I am using Asterisk with misdn connected to an ISDN Line, so I have 
several numbers I can use...

I know that I can use misdn like this in my extensions.conf:

exten => _0.,1,Dial(mISDN/1/${EXTEN:1})

But how can I use another number/MSN of my ISDN connection... it always uses the
default number, but i'd like to use another MSN for calling...
Can somebody help me please?

Thanks, Chris

Hi!

The GX::Transcoder can convert G.729 to wav files.
