The backbone of RingLeader’s communications suite is our proprietary business-class SIP Trunking phone service. The RingLeader Carrier-Connect SIP service seamlessly integrates with any on-premise PBX (phone system) without additional hardware. Simplify your communications by utilizing RingLeader SIP Trunks as a primary or backup phone service over a single data connection.

All RingLeader Carrier-Connect plans are HIPAA-Compliant and meet federal privacy rules. Our VPN-encryption ensures data over our SIP service is not compromised at any time.


RingLeader phone numbers can be used for direct inward dial (personal DIDs) with options for e911 registration and Caller ID.

These type of phone numbers give businesses a presence outside of their physical location. For example, a company based in California can now utilize a phone number with an area code from Texas, Tennessee or Maryland.


Conference Bridge lets you cut down on business travel and make it easy to connect a group of people on the phone at a moment’s notice.
