[cisco-voip] cme 3.2.1. and g.711 to G.729 Codec

[Wes Sisk]

Hi Auker,

CME does not support g729 calls between ipphones homed to the same CME 
router.

you could have your remote site phone homed to CME locally
have the central site phones homed to central CME
define voip dialpeers on the 2 routers and specify g729 codec.

This model is discussed here:
http://www.cisco.com/en/US/customer/products/sw/iosswrel/ps5207/products_feature_guide_chapter09186a00802d255d.html

Another option is to make the remte phone an h323 phone, but lose the 
features.
