[cisco-voip] Progress_ind command

[Wes Sisk]

As you are using an h323 gateway, I suspect the problem is more to do  
with dial-peer matching.  We have seen far more problems caused by  
incorrect peer matching.

here is a decent discussion of progress_ind

For dial-peer matching, every call through the router must match an  
ingress peer and an egress peer.  The VOIP peer you match (whether  
ingress or egress) must have your desired h245 dtmf signal option  
configured.  Keep in mind it could match the default peer (aka dial- 
peer 0) which would not negotiate DTMF relay.

dial-peer matching and dial-peer 0:

Thanks. If a user complained about tones not getting thru, progress_ind
commands would not help unless the reason for no tones was that no audio
connection was established in the first place, correct? In that case,
how would I know what progress_ind command (setup, alert, etc.)to use?
Can you send something that explains it besides the command ref.?
Obviously, I don't know much about the use of this command but want to.
Thanks

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,
