We advise none of our clients to use or advertise ExoPhones as their customer-facing numbers. The fact that Exotel does not own these numbers is the cause.

Instead, the ownership belongs to our operators. If the operators decide to discontinue the number, your clients would have trouble contacting you. If you have your own CFN, the procedure will go smoothly, and if the current number has a problem, you may easily decide to turn on call forwarding on a different ExoPhone.

**Please choose an operator that provides:**

1. **No Call Forwarding tone**:- Make sure you can't hear the "Please wait your call has been forwarded" tone when a call is forwarded. Only Jio does not currently play this automatically. In other operators, the call forwarding tone is played. For Airtel and Vodafone numbers, we can have this removed.
2. **Switch level forwarding**:- Call forwarding takes place at the switch level, so that a customer call will reach Exotel immediately, cutting down on call forwarding time.

Additionally, you may also use a mobile virtual number or a toll-free number provided by Exotel as your customer-facing number for incoming calls, as Exotel has full control over these numbers. Therefore, if there is any issue with the MVN or TFN, Exotel can directly coordinate with the operator to resolve it.

In order to use Exotel, we would require you to use your own number with Exotel, and forward calls from your Existing number to your ExoPhone number, which would then route the calls to your agents.
