[VoiceOps] The peer of my peer is my peer?

  I love the idea of enabling intelligent endpoints to determine their
compatible media formats automatically IF that is what I signed up

  In the UK BT runs a VoIP peering fabric that is very feature rich:

- Video (H.264, others)
- Audio (compressed/narrowband/wideband - iLBC, G.722, G.722.1, etc, etc, etc)
- Probably plenty more

  They also offer a more vanilla PSTN orig/term service that is
limited to the standards we're used to seeing (G711a, etc).  You
purchase, configure, and signal to these groups separately.

  If I want "traditional PSTN" I want it to be with the parameters
specified, regardless of where it goes (on-net, peer, etc).  If I want
"intelligent" VoIP peering I'll configure my routing, trunking, etc
accordingly and use it when and where I want to.
