Hi All,

Could you please give me a clear picture of progress_ind alert enable 8? What is it for?

This is from the command reference

This command overrides the default progress indicator that is sent by  the switch. This enables you to set the progress indicator at the H.323  gateway, if necessary, to ensure the proper end-to-end signaling for  VoIP calls. This command sets the progress indicator only in messages  from outbound dial peers that have a set destination pattern, configured  by using the destination-pattern command. If a message contains multiple progress indicators, the progress_ind command overrides only the first progress indicator in the message.

The disable and no forms of the progress_ind command  have the same result: The call messages are not intercepted by the  session application, and the default progress indicator, if any, is  forwarded unmodified.

PI=8 tells the router that we have an inband stream coming in, telling the router to cut thru the voice ...so that the calling party can hear what the PSTN is sending.!

Hi vinoth

This command is typically required only for fixing ringback issues with service provider ISDN line.

Typically in india you may not hear any ringback when calling some mobile networks and applying this command fixes the problem.

Have a look at this link:

The command is applied at dial-peer level.

Thanks Heaps...
