Probably good idea to have some sort of traditional PSTN backup in this case though.
On the codecs it is really standard practice to use G729 in between branch offices and HQ for example. If the network is configured correctly, I've never had a customer tell me they didnt like the quality.
I have obviously had complaints, when there were QoS misconfigurations or problems on WAN links, but that is not down to the G729 codec.
Main thing to be careful of is the resource requirement.
A couple of things to consider..
1. Make sure you dont compress a G711 music on hold source, it will sound terrible :)
2. IPCC Express - are you using this? It will probably be set to G711 only - so a G729 call will require a Hardware Xcoder to convert.. need to consider how many resources you have available for this..
3. Voicemail - be careful how many G729 calls you throw at it.. by default it will xcode in software, but this will use processor power.. you can use HW resources instead.. so just another design consideration.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
