Because NSEs are sent in the media stream without Unified CM even knowing about them, the switchover to G.711 from G.729 will occur. From Unified CM's perspective the call always stays G.729 since it has no visibility into the codec upspeed.
The main issue that you need to watch out for is the increase in bandwidth. Obviously G.711 consumes more bandwidth than G.729. if you have links where bandwidth is tight and they have been provisioned for a set number of G.729 calls then switching to G.711 can oversubscribe that link leading to voice quality issues. If you do not have this sort of scenario then you should be fine.
