Hi!

Well, the simplest way ist to follow this link here.
But the Page is in german and i believe you don't speak german.

The other way ist to edit the /var/flash/voip.cfg file.
And this will help you only, if you have the export version of the FBF, because the German version comes without the g729 binary.

You need to edit the following lines so:

use_audiocodecs = yes;
audiocodecs = "G729", "iLBC", "G726-32", "PCMA", "PCMU";
dyn_codecs = yes;
prio_low_codec = yes;

In this example the FBF will try to use as first the g729 and as last the g711u (PCMU) Codec. The priority is going from left to right.

But i think that its better that g729 is on the last (rightest) place or before the PCMs, because the sound quality is not so great.

Use only the "nvi" and never the "vi" Editor to edit the file on the FBF.

the above informations was fanstastic but i think that there is no 729 codec at all in my box , when i use the command "voipd" it shows me other codes but no 729!??
i have loaded the last international firmware that the AVM site has available
do we know how to add - load the above firmware?

Hi!

So far i read (not know) in the international Version should be the binary for g729 in side. But i don't know if this it so for all AVM-Boxes or only them without internal ISDN-bus!?

How do you use voipd to see what codec you have?

Are you sure that your provider really support g729?

Normally when you connect to you SIP-provider you must see something like this:

In this case i make a dummy call to bellshare.com. As you see, bellshare is using g729 too, but my box is the german Modell and there is no g729 codec.
If you really have the g729 inside, you should see something else, but not "Not Configured" and not "Not Supported".

as you see there is no presense of G729...

my firmware is the intrnational one....

what is going on?

G729 should be there right?

Hi!

Well, i'm sorry, but it seems that in your Box is no g729 support there. :noidea:
For now, i now for sure only that the international version of FB-ATA and FB-Fon Box have g729 binary's.

Another question, where did you found this international version for 7050?
Are you sure that this is not the german version with english GUI?

Greetings

 

[trkostas]

My box is a German Version as i have mentioned in my first post with a english GUI.
But the International firmware i think its the same for everybody, right? , and it should include G729.

 

[gerdshi]

Hi!

Oh, no, it is not the same!
The international version have the binary for g729 inside. The german version not.
I'm sorry, but this is for me a pain too. ;-)
I use Voxalot.com as my personal SIP-Server between me and my VoIP-Provider. Voxalot.com support g729 very well.

Greetings.
