Pinless service is similar to Calling Card, but without your customers needing to enter a Calling Card number or personal identification number (PIN) in order to place a call. Instead, our cloud-based switching platform identifies your customers via a pre-defined Caller ID which is linked to their Pinless account. For added convenience, your customers can link multiple pre-defined Caller IDs to their Pinless account, such as their home phone, office phone and mobile phone.
