Configure telephony

ChartHero supports provider-backed calling through Telnyx and Twilio. Choose a provider first, then choose the calling mode that matches your workflow.

Telnyx

Telnyx supports two ChartHero calling modes:

• Direct Calling is the simpler, lower-cost option for ordinary one-to-one calls. It uses a Telnyx Credential Connection.
• Multi-party Calling starts as a one-to-one call and lets a ChartHero user add more participants. It requires both a dedicated Credential Connection and a Voice API Application, along with additional provider configuration.

Twilio

ChartHero also supports Twilio telephony connections. A provider-specific Twilio walkthrough is not yet published here. Until it is available, use the settings shown in ChartHero and your organization's approved Twilio configuration.

Never publish provider API keys, SIP credentials, phone numbers, connection identifiers, or application identifiers in screenshots or support messages.
