the PTT button is pressed while dialing the sequence. Once the RoIP accepts the dialed sequence, it
will then play the voice prompt of “Dialing in Progress”. Once the call is answered, the RoIP will
then broadcast a voice prompt of “Call connected” to the radio caller.
Since the called party may not know the call is coming from a Radio party, the mechanism used in 1
cannot be used. Instead, the voice activated detection (VAD) mechanism is adopted. When there
is no voice activities on the radio side, voice signal at the telephone side will be transmitted.
Therefore, both sides will have to adapt to this talking method in order to conduct a normal
conversation.

Application Examples
Example 1: Linking up two MOTO GM300 Radio terminals in peer-to-peer mode with two
RoIP302/RoIP302G. The network access method is ADSL.
Operating procedures:
1. Connect the PTT Interface of the radio terminal (GM300) with the PTT Interface Cable as
shown in the diagram below. Connect the RJ-11 plug of the PTT Interface Cable to PTT1
port of the RoIP302.
2. Connect the RoIP302 LAN port to an Ethernet port of the ADSL Router
3. Assign a fixed IP to the RoIP302 LAN port. This fixed IP must be in the same segment as
the LAN port of the ADSL Router. For example: if the LAN of the ADSL Router has an IP
192.168.1.1, then the LAN port RoIP302 could be set to 192.168.1.101.
4. Configure the DMZ mode of the ADSL Router to fixed IP assigned to the RoIP302 LAN port.
For DMZ configuration, please refer to the User Manual of the Router.
5. Login to the RoIP Webpage and program the Network Settings as shown below. Please note
