The Communicator GO app turns your mobile into your office extension — make and take business calls, chat with the team, and check voicemail from anywhere, over WiFi or mobile data.
Setting it up
Install Communicator GO from the App Store or Google Play, then sign in one of three ways:
- QR code (easiest): scan the QR code from your welcome email, from the desktop Communicator app, or from your Self Care Portal. The email QR works once and asks you to set a new password.
- Manual: enter your email address, password, and the server address from your welcome email.
- SSO: tap SSO Login, enter the server, and sign in with your provider.
Allow the microphone and contacts permissions when prompted — it can't make calls without them.
Good to know
- Green call button = call over data (normal). Yellow button = callback mode, handy when data is poor: the system rings your mobile and connects the call.
- VPNs interfere with calling. If calls won't connect and you run a VPN on your phone, disconnect the VPN and try again.
- Your call history syncs with your desk phone and desktop app.
- Voicemail, chat (with attachments and voice messages), the company directory and favourites are all built in.
- On mobile data, "Use SIP over mobile networks" is on by default — calls use a trivial amount of data.
Troubleshooting quick hits
- Can't sign in: your login is the same as the desktop Communicator app. Not sure? Ask us or your admin.
- Calls fail on WiFi: try the yellow callback button, or check the VPN note above.
- Poor call quality: the in-call quality indicator (MOS score) helps us diagnose — screenshot it and raise a ticket.
