7170 und g.729

[skalita]

Hello,

Does 7170 support g.729? I expect not. So here is my question: how can I modify firmware to have g.729 supported?

This is a codec that needs to be licensed - there's no free version. It is not included in the AVM products.

Hi gandalf,

But I am sure G.729 and G.723 are included in 7050. At least in avme version.

In my 5050 (firmware .04.01), only the following codecs are defined:

PCMA: 98933 bits/second (encaplen=14,30ms)
PCMU: 98933 bits/second (encaplen=14,30ms)
G726-32: 56533 bits/second (encaplen=14,30ms)
G726-40: 70666 bits/second (encaplen=14,30ms)
G726-24: 56533 bits/second (encaplen=14,30ms)
iLBC: 42400 bits/second (encaplen=14,30ms)
PCMA: 106000 bits/second (encaplen=14,20ms)
PCMU: 106000 bits/second (encaplen=14,20ms)
G726-40: 84800 bits/second (encaplen=14,20ms)
G726-24: 63600 bits/second (encaplen=14,20ms)
iLBC: 63600 bits/second (encaplen=14,20ms)

When you telnet to your FBF and do "voipd -s" to stop the voipd, then "voipd" to restart it again, the voipd will output lines like the ones above, listing all registered codecs. Does this list contain G729?

No it doesn't. I will ask friend of mine to do the same with 7050.

Here is a list from 7170:

voipd: PCMA: 98933 bits/second (encaplen=14,30ms)
voipd: PCMU: 98933 bits/second (encaplen=14,30ms)
voipd: G726-32: 56533 bits/second (encaplen=14,30ms)
voipd: PCMA: 106000 bits/second (encaplen=14,20ms)
voipd: PCMU: 106000 bits/second (encaplen=14,20ms)
voipd: G726-32: 63600 bits/second (encaplen=14,20ms)

Is it possible to use voipd from 7050 in 7170?

Did you really find G.729 in the 7050? Which firmware version was that?

In any case, replacing voipd from one system by that of another seems plausible as probably no dependencies on the actual hardware configuration would (hopefully) be built in. However, as you try the experiment, make sure it's the same firmware version. I've not heard of anybody try that before... ;-)

I have seen many posts on a polish newsgroup saying that g729 is implemented in 7050 (avme version). I do not remember the exact firmware version, but it was for sure pure avme version.

Could you tell me your result for this command:

grep -i g\.7 /bin/voipd

[skalita]

There is no difference between voipd for 7050 and 7170 (firmware 04.01). I suppose the problem is hidden elsewhere (but for sure not in hardware).

Here is a small proof.
