I am using G.711 with UCM 6.1, we also have a SIP trunk where telco requires us to use G.729r8. I was doing some packet captures and I noticed all inbound/outbound pstn calls are G.711. The voice class codec on the router only contains the 729 codec. I understand these calls are being transcoded on the gateway, but i don't understand how G.711 is negotiated instead of G.729

I tried doing some debugs on the dial peers and I am getting predictable results with hitting the dial peers, but I am still seeing G711 on PSTN calls from the VoIP phones. I setup a test where I made 10 calls from the PSTN to one of my internal extensions. On 8 of the calls the codec was G711 and twice it was G729, even though the dial peers matched were the same each time. I can see that when G711 is the codec the UBE router is transcoding; I can see that with the "show dspfarm dsp active" command. I am just not understanding the arbitrary nature of the codec selection.

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...
