number. It supports a user-friendly dialing method as described below.
Warning: You need to have Internet access information and VoIP Calling Card information
configured in DPH-70L to make and receive Internet calls.
5.1 Receiving Internet call

of digits after which phone should wait for secondary dial tone before dialing remaining ISP phone
number in this option. Configure ‘0’ to disable this option. For example, if ISP phone number is
96788341 and wait for dial tone is configured as 2 then phone will dial first 2 digits i.e. 96 and
then it will wait for secondary dial tone before dialing other digits (788341). This option is used
only for dialing ISP phone number.

enable this feature for dialing ISP number in blind mode. Default mode is ‘DISABLE’.
