FXO-M1 - some weird sound right ofter hang-off

[lterebizh]

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.

I am not familar with the sound you are hearing but I do know there where a lot of bugs with the M1 cards in 12.1 code so I would just stick with 12.2.6. That will give you other fixes that will benefit call manager as well.

Thank you,
