[Asterisk-Users] Digium G729 licensing - is it worth the trouble?

Mon Jun 6 04:50:49 MST 2005

If the incoming extension is using CodecA and the call is made to an
extension that prefers CodecB, Asterisk will connect the two calls and
transcode all the ausio. You don't have to do anything, except to make sure
the equipment you are connected uses a supported codec. 

You can force the chosen codec or set order of preference with 

disallow=all
allow=codecA
allow=codecB

in the configuration stanza for each device.

could you please explain the transcoding to me? How do i have to configure
this?

Yes, I use the phones on a LAN and don't care about the bandwidth, then
allow Asterisk to transcode to GSM for trunked calls. I was using G729 all
the way, but the licensing stuff caused me too many problems.

WHen I messed up the licensing by allowing the order of the modules to be
reversed, thereby putting eth0 and eth1 on different NICs, it was a holiday
weekend, and I was not able to get anyone at Digium until Tuesday. They
still would not permit the relicensing. We ended up three days without the
codecs we paid for, and so I had to re-engineer the system, moving the
phones to uLaw and using gsm at both ends of the trunk. For reliability
reasons I would not advise g729. If you lose a NIC, or you are using the
motherboard's interface and it fails, you will have to relicense. If that
fails, you have to restructure everything.

We want to build the new Asterisk PBX with the Polycom 500 IP phone.
So G.729 is the only alternative for small codec for WAN calls, isn't it?

I think you are at least morally correct, I think I might do that.

However, I guess part fo the question is, does it make much difference, am I

that badly off without G729?

The other point it, doesn't Digium realize they are pissing customers off

with their attitude? I took a lot of my time to explain my situation, send

them a letter, call several times, and they still won't allow me to use what

I paid for. Is it my fault they have a stupid and unworkable enforcement

system? Is it more important to prevent piracy or keep customers? I think

they have it backwards.

They're also really bad about supporting the activation of the codecs

when you do buy them...I bought 6 of them (3 for each site in this

case), and tried to activate them through the customer's very

restrictive firewall. Of course it didn't work since the firewall

doesn't allow arbitrary port numbers to leave the network, and they

have never even returned my calls on the issue. It wouldn't really

bother me as much if they'd at least have had the courtesy to call me

and tell me it was not possible to activate them over some other

method (manual, http, https, etc).  I've still got all 6 of them

completely unused because of that. I'm now very selective on when and

if I'll use g.729. My advice is to use anything else first, and use

g.729 as a last resort.
