3.7 Call Forwarding (Setting on the Call Route and
Authentication Mode)
The gateway provides the call routing function for users, which can be set in the Call Forwarding
Setting. The call routing is to forward calls to specified numbers, so that the dialing time can be
decreased. In addition, the gateway provides three authentication modes for the uplink (calls from
PSTN to VoIP) and downlink (calls from VoIP to PSTN). Do not set these parameters when they
are not needed.
3.7.1 Call Route Setting
Downlink: from VoIP to PSTN
Uplink: from PSTN to VoIP
Note: The value of Call PSTN must be Enable. Otherwise, The GoIP prohibits any access to the PSTN. Therefore,
set this parameter carefully.
The above Note is also suitable for Call VoIP.
1. Set a hotline number in Call PSTN Forwarded-to-number. When the user served by the VoIP
network calls the GoIP, the call is forwarded to the hotline number.
When the user served by the VoIP network calls the GoIP, the GoIP gateway connects the call and
dials 88290211 directly. This feature is especially useful for hotline services.
2. Set a VoIP number in Call VoIP Forwarded-to-number. When the user served by the PSTN calls
the VoIP network, the call is forwarded to the VoIP number.
When a user calls another user served by the PSTN, the HT-342 calls the 3306 terminal of the
VoIP. When the 3306 terminal answers the call, the HT-342 connects the call and the call will be
connected. This feature enables international roamers to answer the phone through the VoIP
anywhere.
3.7.2 Authentication Mode Setting
The authentication mode is classified into the password authentication, trust list authentication, and
password or trust list authentication.
