Configuration
Enable the Call Waiting function of the FXS port (D) of M3700 gateway. This function can be
configured for each FXS port individually.
Web Folder: Channel\
Connection Type
A: FXS port of M3700 Series
B, C: SIP Device (M3700 Series, other brand SIP gateway. SIP phone...), Normal PSTN phone call
(special condition is described below)
Call waiting function works only on SIP call. So PSTN call works when it is transited as SIP call. If
Inbound transit call is configured on M3700 (please refer to 7.9 Make Inbound Transit Call), then
Call Waiting function is available when user dials the SIP number of this M3700 gateway itself. If no
inbound transit call function is configured, it is impossible to do call waiting function.
