📞 Voice Calls and Call Flows
Make and receive voice calls directly inside Zendesk using your connected Twilio number.
Features include:
- Phone Settings: Customize hold music for callers on hold, and configure voicemail to capture messages when agents are unavailable. Define a fallback number to ensure call continuity—if your application is unresponsive due to server issues or timeouts, Twilio will automatically route the call to this number.
- Welcome Message: This is the initial greeting a caller hears. You can configure it using one of the following methods: Text-to-Speech (TTS) – The system reads out your custom message. Play Audio – Upload a pre-recorded audio file. URL – Provide a URL to stream audio from.
- Call Recording: Enable or disable call recording based on your needs. You can optionally inform the caller using a message node before recording starts — customizable using TTS, uploaded audio, or URL-based audio.
- Business Hours: Control call routing based on defined working hours: Opened – Directs calls to available teams or users. Closed – Plays an unavailable message or redirects the call as needed.
- Route Calls: During open hours, route incoming calls either directly to a team (e.g., Sales, Support) or through an IVR menu for structured call distribution and better caller experience.
- Ring Team: Define which team the call should ring. Choose between: Parallel Ringing – All team members receive the call simultaneously. Sequential Ringing – Call each user one at a time in a defined order. You can configure the ring interval (how long each user rings) and repeat count (how many times the sequence repeats) to ensure the call is answered.
- No Answer Scenario: Specify the fallback behavior when no agent answers. If all agents are busy, the system plays a Busy Message. If all agents are offline, the call plays the Unavailable Message. Both messages support three configuration options: Text-to-Speech, Audio Upload, or URL.
- Unavailable Message out of business hours: Triggered outside business hours or when no agents are available. Delivers a closing message using Text-to-Speech, Audio Upload, or URL, then ends the call.
- Note: All message types—Welcome, Busy, Unavailable, and Recording prompts—can be configured using Text-to-Speech, Audio Upload, or URL input.
