When I make call to M1 card... I can hear this sound...
It seems to be request for CallerID...
I use H.323 ateway (Cisco 3662).
I am using 12.1(5)T7....
IOS 12.2.6 do not have this sound....
Does anybody know command to get rid of this sound and use 12.1(5)T7...Or it is better to use 12.2.6 ?
Thanks in avance.
