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?

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.
