RoIP Options
IP Connectivity Methods
There are a number of IP connectivity methods to connect Radios over IP, depending on your IP network. The table below explains the Advantages and Disadvantages of each of the methods.
Unlike many competing products, the Omnitronics Range of IP Gateways support all the below connectivity methods. Contact Us if you have any questions about your particular network requirements.
White Paper
Understanding RoIP Networks
Radio over IP differs from Voice over IP technology in a variety of ways. This White Paper explains those differences and the various considerations the IT team and systems integrators need to understand in order to create effective RoIP networks that meet their needs.

Connection Method
Unicast Real Time Protocal (RTP)
Advantages
- Constantly connected – if the IP link fails at any time, it can be immediately detected by the console software and warn the user
- Can be used over the internet – as it can be configured to work via Network Address Translation (NAT)
Disadvantages
- Requires static IP addresses for all parts – there could be additional cost from the IT service providers as Dynamic Addressing is not used
- Limited operator positions – due to the point to point nature of the protocol
- Greater configuration of end devices – especially when multiple transmit designations are required
Multicast RTP
Advantages
- Constantly connected
- Bandwidth efficiency – more voice path can be transported over the same IP network than other
- Simplified configuration through the use of dynamic IP (DHCP)
- Supports more consoles & end points on the same IP network
Disadvantages
- Won’t work over the internet – LAN/WANT only
- Complex setup – many IT administrators will not allow multicasting schemes over the LAN or WAN
- All network devices need to support multicast – this could be costly and time consuming
- Difficult to identify potential problems when used with more than a single unmanaged switch on a LAN
Secession Initiated Protocol (SIP)
Advantages
- Connected only when required – the IP network is freed up to be used by other devices thereby reducing overall bandwidth requirements
- Simplified configuration – through the use of dynamic IP (DHCP) & there is no need to configure the destination addresses of the receiving units
Disadvantages
- Doesn’t work well where there is Bad Packet Loss – if the IP link falls at any time, it cannot be immediately detected by the console software & warn the user without considerable overhead
- Can have issue with NAT and firewalls
- Many IP networks are not naturally configured for SIP – firewalls will prevent the SIP packets passing through the router and stopping a link being made
Omnitronics Unique Conferencing Mode
Advantages
- Enables point to multipoint comms – without the need for multicast support
- Reduced router configuration – to achieve the same result as multicast
- Can be used over the internet – as it can be configured to work via Network Address Translation (NAT)
Disadvantages
- Requires static IP addresses
- Restricted to a smaller number of devices
- Great configuration at the end devices as compared to SIP or Multicast
- Less bandwidth efficient than multicasting
