[cisco-voip] Progress_ind command

[Wes Sisk]

progress_ind really has very little to do with DTMF.

progress_ind determine *WHEN* audio is cut through.  Though that  
audio cut through (actually the associated h245 session) is a pre- 
requisite for DTMF exchange, the 2 are not directly linked as you  
seem to imply.

Does anybody know if ANY progress_ind command is needed to make sure
DTMF tones get thru the IP phone network to/from a PSTN destination?
I've been experimenting and find that the "dtmf-relay h245-alphanumeric"
command breaks DTMF tones but the progess_ind commands have no effect.

"ringback" problems with the "alert" key word but not sure about "setup"
and "progress" key works.
Thanks,
