How it works

What is SIGNL4?

SIGNL4 is your call routing solution and supports both live call routing and a voice mailbox which can notify your staff on duty about any voice recording. It is a plug & play solution and set up within minutes. SIGNL4’s Call Routing provides your customers or staff members with a phone number to call. Incoming calls are then conveniently and automatically routed to a person on call.

Never miss a call

Call Routing

SIGNL4 provides a phone number customers or other staff can call. SIGNL4 automatically routes the voice call and connects your customer to an available person on call.

Never miss a voicemail

Voice Mailbox with Alerts

If nobody is available or if live call routing is not part of your process, an integrated voice mailbox records a message (e.g. from a customer) and then alerts on-call staff on their mobile phones. When they open that alert in their SIGNL4 mobile app and press the ‘Play’ button, they can listen to the recording/voicemail.
