network annaouncement

I using cisco GW 3500, getting traffic from isdn to SIP.

I have problems with toll-free numbers because they have “network annaoucements” – the “connected” signal is not sent and the timers expire by thr time the annaouncement end.

I want to replace the annaouncement signal with connected. (20OK at the SIP).

I think the solution should be with the command “progress_ind” but no success yet.

here is the one of the dial-peers that I tried:

dial-peer voice 1800 pots
huntstop
preference 1
destination-pattern 18007623726
progress_ind progress enable 8
progress_ind connect enable 8
port 3/0:D

Thank You
