DialTone
Description
The Cisco ATA plays the dial tone when it is ready to accept the first digit of a remote address to make
an outgoing call.
This parameter is for specifying the inside dial tone in SCCP. The outside dial tone in SCCP is fixed at
450Hz+540Hz@-6dBm. The inside dial tone is the tone that the telephone plays when a phone inside
the PBX goes off-hook. The outside dial tone is the tone that the telephone plays when a phone inside
the PBX is connected to the PSTN.
