Long Conversation Alert

[spring]

There is a "do do" tone heard on digital/analog phone every 5 min. when he/she told with external call. Anybody know how to disable this alert tone

Hi Spring,

Is it happening in incoming or outgoing calls?

If outgoing, did you check the timer 85. The default value is 1200.

May be - phone feature COS, item "Beep On Ext.Call"?
