Frequently asked questions
I'm using traditional voice services. How quickly can i switch to VoIP?
You can switch easily by creating a new Exotel account with a UL-VNO (Veeno) tag to ensure compliance. Your agents can start making and receiving VoIP calls via the Exotel dashboard or your CRM. For in-app VoIP calling, simply integrate our Web, Android, or iOS SDKs.
Will international call quality be affected with VoIP?
Not at all. Exotel’s globally distributed edge locations ensure minimal latency and high call clarity. Businesses in over 17 countries trust our VoIP service for crystal-clear international calling.
How does VoIP improve call pickup rates?
VoIP itself doesn’t impact pickup rates, but with Exotel’s UL-VNO license, you can enable PSTN fallback—boosting call connectivity. Plus, on-screen caller context helps users identify who’s calling, increasing the chances they’ll answer.
How does the fallback mechanism work?
If a call is made to a SIP ID and the user’s phone number is also provided, Exotel automatically switches to a PSTN call if the user has no internet—ensuring the call still goes through.
