I'm not sure about the license requirement. If you use CME and SIP Trunk, then the it is not cube functionality. So you do not need CUBE license.
Regarding the transcoding, you do not need transcoding. Because IP Phone supports both G711 and G729. So when there is call between IP Phones, it will be G711. But when calls are coming from PSTN over sip trunk, it will use G729. Just make sure you have SIP Dial-peer to/from PSTN SIP Trunk configured only with G729
There is nothing about licensing for SIP trunks in the CUCME ordering guide so I guess that you do not need anything - I just expected Cisco to want to charge for this functionality (getting cynical in my old age).
The codec response makes sense. I would guess that transcoding would be needed if I had a Unity Express module installed as that only support G.711?
I have Cucm10.5 and 2 voice routers 2921 and 11 E 1 lines and I want to make a SIP trunk with my provider in order to not use anymore the E1 lines. Any ideas if i need licence or something extra in order to create the connection.
Can i create directly from cucm or i have to create the SIP directly on the router ??

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
