Note 0

If the PSTN line is the default mode and PSTN line is used by one port, then

off hooking the other phone the user will hear a busy tone. In order to make

a VoIP call it will be needed to digit the set prefix.

Note 1

In this case, if the AT-RG213 has an incoming PSTN call, it will signal the

incoming PSTN call using a tone that is ON by default (a parameter in the

SET phone command will permit to modify this default CWAITT from ON

to OFF).

This tone has:

 the same periodicity of RING provided by the PSTN

 a fixed frequency (425 Hz) and duration (see diagram below)

 this tone will be provided by default for 30 secs (if the caller from

PSTN hang up the phone before 30 secs the tone will be stopped); a

parameter in the SET phone command will permit to modify this

default CWAITD from 0 to 60 secs)

 if the user closes the running VoIP call hanging up the phone, then

the phone will RING and it will be able to answer to the incoming

PSTN call.

As an example Figure 19 shows, in the upper diagram the RING tone

provided in Italy from the PSTN, and in the lower diagram the tone that will

be generated by the AT-RG213.
