Make sure you're matching the right outbound DP in CME by using the debug voip dialpeer command. Also try to put the CUCM trunk in a device pool with a region that only allows g729 calls. Are the CUCM and CME in the same local zone in GK or do you have multiple local zones?
The config looks good. What do the statistics say on the phones as to what codec is being used? If your dial-peer is set to 729 and the CUCM trunk region is 729, I don't see how 711 is being negotiated. If the phones say that 729 is being used then my guess is that there is some bug pertaining to the gatekeeper BW.
If 711 is somehow being negotiated by the phones, then I'd say that maybe the call is always failing when matching dial peer 202 (or on the CUCM side with 729) and then trying another dial peer that has 711 as the codec.
Do you have the MTP checkbox checked on the GK trunk in CUCM? If so keep in mind that a SW MTP cannot be used with the 729 codec.

If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
