many thanks!
it's all pretty much a hit & miss process
becaues of Asterisk's notorious lack of documentation..

I will try this out at my client tomorrow,
fingers crossed.

cheers
Dave

Hi,

Unless there has been a recent change, you can't set codecs in the
sip.conf
on a per-context basis. The way to do what you want is to have the
following
in the [general] area:

 disallow=all
 allow=ulaw
 allow=alaw
 allow=g729

 Then, set all the codec preferences on the g729 phone to g729. That phone
 should then only be able to negotiate g729. If this doesn't work then I
 suspect some sort of g729 codec installation error?

hi there .. I asked sometime ago regarding getting a Budgettone working with Asterisk over G729.

 My system is quite simple, Asterisk server with 1 G 729 license
 installed, and 10 Grandstream phones. Only one of them needs
 G729, because it's on a remote link via an ADSL bridge. The
 rest run happily on G711 on a local network.

I added the lines

 disallow=all
 allow=g729

 to the sip.conf entry for that particular phone,
 but it doesn't seem to have made any difference.
 If I remove the "allow = g729" line, which supposedly
 should leave no codecs at all, the phone still works,
 on G711. With the allow=g729 line in place, and switching
 off all codec options except g729 from the phone, when
 I try to for example dial extension 1000, which should
 give me Asterisk's welcome message, I get a message
 about "no matching codecs" on the asterisk console,
 so obviously the g729 codec isn't working.

Can somebody help?

cheers

Another point to reference is that there is a feature request in the system to allow/disallow codecs on a per-peer basis:
