[cisco-voip] Where is ring back generated?

Ringback is generally the responsibility of the "far-end" terminating
device.

So in your scenario below the Tandberg gateway should be generating ringback
to the PSTN based caller.

As part of my continuing effort to mess around with stuff, I've got a
Tandberg 3241 PRI gateway terminating PRIs from MaBell.  It has a H.323
connection to a 2851.  Inbound callers don't hear ringback, but there is an
audio path once the called person goes off-hook.

Can someone who's deeper into H.323 let me know where the ringback is
supposed to be coming from?  Should the Codian generate ringback
immediately, or is it waiting for a H.323 message from the Cisco, or is this
just in the "too hard to do" category?
