G729 audio codec not supported?

Recommended Posts

I purchcased Bria on my iPhone (www.counterpath.com), and I adquired the G729 Audio Codec (to use on 3G networks).

 

If I try to make a call using G729, I get Unsupported Media Type (415)

 

THanks for any help...

You also need the codec license on the PBX...

 

Ok. Wish there was some kind of informatino about that on the Admin pages.

 

How can I check what codec is being used for each extension connected?

In the SIP trace, you must have number "18" in the codec list. In the license key, there should be some kind of hint (the key is base64-encoded, so if you decode it you can also see what features were included. "lowrate" is the keyword for the codec 18).

Thanks for the info. Seriously when I purchased the CS410 (2+ years ago) there were no addons listed. At the time I purchased the unit paying the only retail price it had ($1199) , and I never figured I was getting a crippled deviced with deactivated features.

The problem is that G.729 is a CPU-killer (well at least for embedded systems). The CS410 has only a small ARM CPU and G.729 is pushing it to the limits very soon.

How many users do you have on the cs410?

What type of handsets?

About 7 users (2 mobile). Only the mobile ones were supposed to use G729

snom phones?

pstn lines?

 

 

If so, perhaps consider snom ONE?

use low cost server hardware? (hp proliant microserver only $350 usd)

could you re-use cs410 hardware pstn gateway if needed? (i've never done it)

 

I havent verified about g729 though. its a question about snom ONE i'd like answered.

 

With the experience i've had i'm done with appliances that "just so" get by on cpu/resources. Its a whole lot better in my mind to have a plateform/os that can do the job and your familiar with. Just my opinion there. ;-) (and i have plenty ;-)

 

just some wild ideas to get solution ideas rolling.
