ROIP-102 Radio Repeater or Radio Trunking SIP Gateway Full PTT control (IETF SIP V2)
What is a Cross-Network Gateway?
Who needs a Cross-Network Gateway?
i. This product is used to link up the civilian radio network, internet, and cellular phone network. Its operation and performance rely on the broadband network connections via private and /or public internet networks and the cellular phone networks. Due to the stability and reliability of these networks, this product may not be able to link up all the networks connected without any interruptions. Therefore, it is not recommended to use this product in an emergency system or a communication system with zero-failure.
ii. This product can bridge and extend radio networks all over the world.
iii. This product requires the use of dynamic DNS(DDNS) service.
iv. Customers and / or users are taking full responsibilities and all risks in using this product. We are not responsible for any direct or indirect use.
The fundamental of RoIP Radio over IP technology is to convert the audio and PTT signals in a radio terminal into IP packets and then transmit the data via the IP networks. The challenge in this technology is to insure that the audio is transmitted in real time and the PTT control signal is transmitted immediately and reliably. The radio range is general limited by the restricted transmitting power, the antenna sensitivity, and other environmental factors. The success deployment of this technology extends the coverage of a radio network without using expensive repeaters or links up multiple radio networks in the world. In addition, this technology can also link up the radio world to the VoIP world and the cellular world easily. It truly makes voice communications across multiple networks possible.
RoIP-102 basic version is a more compact, more practical high-tech multiple network (Radio, Cellular, VoIP) equipment, which access to a group, no GSM module, simply complete the radio voice signals into IP signals, access to the Professional Edition or Standard Edition RoIP-302M group (Witch is avalable on request, Asterisk server can also be used), to achieve the client and the central station intercom communication. Also has a remote control switch interface, which enables radio remote control.
RoIP102 gateway can be installed in IP networks with intranet or internet connections via ADSL / LTE modem, Cable modem, or Local Area Network (LAN) . The unique built-in DDNS client can help to simplify the installation and configuration without relying on a voice relay server in order to achieve interconnections among RoIP Series gateways.
Physical and Environmental
Basic link logic diagram:
Cell to Cell (Repeater to Repeater)
Basic network mode: Internet between multiple places.
Seen from the diagram above, in Place A, RoIP302GM with conference system or Asterisk server is used as a central switching point. The other three places use RoIP-102. Through this link, the radio network in places ABCD can be interconnected.
Link and Installation :
Host Connection :
Application Example :
Linking up two MOTO GM300 Radio or equvelant terminals in peer-to-peer mode with two RoIP-102. The network access method is ADSL.
i. Connect the PTT Interface of the radio terminal (GM300) or equivelant with the PTT Interface Cable as shown in the diagram below. Connect the RJ-11 plug of the PTT Interface Cable to PTT1port of the RoIP-102.
ii. Connect the RoIP-302(which you can get buy from our ebay store too) LAN port to an Ethernet port of the ADSL Router
iii. Assign a fixed IP to the RoIP-302 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.
iv. 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.
v. Login to the RoIP Webpage and program the Network Settings as shown below. Please note that the DNS addresses should be programmed as provided by from your local ISP
Domain name server address on the above map according to local service providers’ domain name server address (DNS) to be adjusted.
GM300 in the PTT (COR) is low input and output RMS, so PTT settings are :
A: set for the host, the number is set to 101,the body number is :
ROIP2010060005,DDNS,and call setup is as follows:
B: body number ROIP20100610006,the DDNS and call settings is as follows：
where xxx in www.xxx.com is host A inside the body number, such as ROIP20100610005
Connected to only one radio in two side, so the group set as follows:
Choose the best sound quality for Communications, so both sides have chosen alaw as speech coding:
Complete the connection, save the configuration after the restart RoIP102,open the Radio, the two place can Communications, After connecting through the respective end of the potentiometer adjustment adjust the volume to the best sound quality
(DMZ’s Settings, please refer to the router manual).
