[cisco-voip] Where is ring back generated?

[Lelio Fulgenzi]

I remember from my voice over course (this was h323 peers and gateways, not 
the CCM course) that ring back was actually the responsibility of the local 
device. For example, you could change the cadence you would hear when 
dialing a dial-peer. Now some of those dial-peers were pointing to another 
box in the lab, so when i would dial an off-box phone, it was my router 
giving me dial-back.

Now, I believe it waits for the H323 signal to tell it what to play, i.e. 
ring or busy.
