Primal Technologies has developed many applications on the Primal Service Node over the past 5 years. These applications include; Voice Mail, IN Prepaid, Primal Messenger, Personal Operator, Conferencing and Voice Response. All applications can operate simultaneously on the OSP with restrictions dependent on traffic engineering in and out of the service node. Presently the OSPs have been designed to support up to 500,000 customers and 10,000 hours of voice messages depending on T1s/E1s and disk storage.

Voice Mail has been developed to emulate many DTMF schemes including Nortel, Lucent, and Glenayre. Primal Messenger provides Unified Messaging enhancements to Voice Mail with some features including; subscriber call control of inbound calls and emailing voice messages to your email address book. With and without Primal Messenger customers can establish 3 to 32 people Conference calls with no Operator intervention.

One of the major strengths of the OSP is the rating engine that has been developed on the OSP. The domestic and international rating engine of the OSP with detailed CDRs allows the service provider the capability to rate and bill the customer for applications on a monthly or per transaction basis. Many Service Nodes in the industry do not have this capability for a complete turnkey solution and therefor have to depend on external integration development to their non real-time billing/provisioning system. The Primal rating engine has been used by many wireless companies offering wireless prepaid service.
