Why should we have a different Customer Facing Number (CFN)?

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 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 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
