You would configure this in Call Manager. I would use Regions to specify the codecs used between sites. As an example, Chicago (hub) uses G711 for calls with phones at Chicago. (We don't care about 80k calls over Ethernet) From Chicago to St. Louis (goes over a WAN) we only have a 64k circuit, therefore 1 call would comsume the whole link. So here is where you create a region for St Louis and configure call manager such that Calls from St Louis to Chicago will use G729 and calls local at St Louis use G711. Also, I'll add that its important to know the company's call patterns. If they have heavy call patterns between offices, this may be a good business reason to bump up the speed of your WAN links.....If they mostly call out of their local gateway, then configuring G729 may not be an issue. As a rule of thumb, for the best voice quality, use G711 wherever possible.

the softkeys. You enable or disable them via TCL. Here is the long
