Deltapath emphasizes its product being open and strictly SIP, hence the name "for reals" SIP. Unlike other competing brands, Deltapath does not have its own proprietary protocol, all signaling follows strictly the SIP standards. By using open standards like SIP, our customers will be open to connect any SIP compatible devices without difficulties, potentially linking up with any other SIP based PBX or UC core in the world.

Besides SIP integration, Deltapath has a suite of open application programming interfaces (APIs) that allows you to integrate with your favorite business applications such as CRM and ERP. APIs give customers the flexibility to integrate their internal business process applications with their business communications systems. For example, you can have frSIP® call centre to send call data to your CRM application enabling you to create customized screen pop-ups and war board. Your CRM application also allows your agents to click on a customer's number and have it dialed out automatically from his/her deskphone. You can also have your ERP systems to send SMS messages to customers, suppliers, or employees whenever a specific transaction happens. Our APIs are available to all customers. We are continuously expanding our APIs base on field requirements. Please contact our Professional Services team for a copy of the API guide or to suggest a feature request!
