[cisco-voip] Modem PassThrough

[Scott Voll]

Modem pass through is just like Fax passthrough.  both need to run over a
G711 codec.

config is pretty simple.  just add the following commands:

H323 looks like this:
 voice service voip
 h323
 modem passthrough nse codec g711ulaw

Also make sure you have VAD turned off on the dial peer(s)

MGCP looks like this:

mgcp modem passthrough voip mode nse
