RadioPro Talk™ App FAQ

  • How are the user accounts for logging on to the RadioPro Mobile app administered (i.e. created, deleted, password reset)?

This is controlled or monitored by the admin on the IP Gateway through the ICU.exe utility. This utility is used to configure static IP address, as well as User Names and Passwords for the Mobile app users. User Names and Passwords may be created and deleted using this utility.
See the RadioPro IP Gateway Installation Guide page 16 "Solo/Talk/Talk Mobile Clients".


  • How many people can connect and talk on the mobile app, if you only have one license?

One smartphone will have a permanent connection while one person can talk on the radio system at a time. However, there is a provision in the license, so that if a second or third person tries to connect, they will be given 5 minutes of connection time before being booted off.


  • If someone connects, does it stay connected until they disconnect or does it time out?

They stay connected until they disconnect. If the connection is temporarily lost due to cellular data tower switching, the app will attempt to reconnect to the IP Gateway.


  • Will the mobile Talk app allow incoming phone calls while the app is running?

Yes. You can still receive phone calls while using the app.

  • iOS devices: You will not be able to hear incoming transmissions while on a phone call.
  • Android devices: Incoming transmissions will interrupt your phone call. Version 1.11 adds a switch to block radio traffic during a phone call.


  • Does the Talk App support DHCP?

Yes. The RadioPro Talk™ app installed on Android and iOS devices supports DHCP.

CTI Products recommends that a static IP address be configured in the RadioPro™ IP Gateway using the ICU Configuration Utility. It will not follow the DHCP changing of the IP address.


  • Does the Talk App support DNS?

Yes. The RadioPro Talk™ app can connect to Gateways that have a static IP address associated with a Domain Name.

The RadioPro™ IP Gateway must have the following:

  • A static IP address.
  • port forwarded from an Internet exposed IP Address.
  • the exposed IP address must also be static.
  • A registered Domain Name.

  • Why does the connection drop and not reconnect when switching from Wi-Fi to cellular?

  1. The cellular network that your phone is switching to may not have enough bandwidth.
    RadioPro Talk™ App V.1.8 added an option to enable data compression.
  2. The IP Address of the RadioPro™ IP Gateway may not be reachable from your cellular network.
    Configure Port Forwarding. See the RadioPro IP Gateway Installation Guide page 19 "Configure Port Forwarding".


  • Why does the connection drop and not reconnect when switching from cellular data to Wi-Fi?

A RadioPro™ Talk app connecting through the Internet(cellular), may pass through a different set of firewall rules than a RadioPro™ Talk app connecting through a Wifi connection.

  1. It may be necssary to have 2 connections set up in the RadioPro™ Talk app. One for the Wi-Fi connection that looks like 10.xx.xx.xx or 192.xx.xx.xx and the other that has the static IP address exposed to the internet.
  2. The Network infrastructure that hosts the RadioPro™ IP Gateway may need a modification to allow access through the Wifi Firewall. The documentation for Port Forwarding may be helpful in this case as well. Please See the RadioPro IP Gateway Installation Guide page 19 "Configure Port Forwarding".
