Tongan business calling
A few things
worth knowing.
Can my team call contacts in Tonga?
The current voice catalog lists supported landline and mobile destinations for Tonga. Check your complete destination number in the portal before calling.
Will calling automatically update our appointment calendar?
No. Calendar changes are managed by your application. A custom Voice API integration can add calls and events to that workflow.
Can we keep our existing phone system?
Connect a compatible PBX or SIP phone through IllyVoIP SIP trunks. Teams can also use Windows, iOS and Android apps, or the browser webphone.
Can our software receive call updates?
Voice API webhooks provide call events for a custom integration. Your application decides how to associate them with its customer or project records.
How do we discuss incoming-number options?
Contact our team to discuss incoming-number options and the calling setup you need.
