PsipTN architecture

PsipTN consists of thousands of physical servers operating under TelTel networking technologies located at major data centers around the world.

The PsipTN Core Network consists of SIP proxy servers, Presence servers, Login servers, Billing servers, SOAP servers, P-Servers and Database servers. Collectively these servers form the core of the PsipTN backend and provide a highly scalable, secure and partitionable architecture which allows extreme extensibility for virtually any type of devices, applications and management software operating under the PsipTN.

The PsipTN Feature Server Network is a set of servers which provide application specific feature support which currently includes Conferencing servers, Call forwarding servers, Auto-provisioning servers, Event servers, Configuration servers, IP Camera servers and Phone recording servers. The PsipTN Feature Server Network seamlessly integrates with the PsipTN Core Network to provide the business logic necessary to support PsipTN hosted applications.

The PsipTN Edge Server Network consists of a set of servers responsible for firewall traversal using TCP tunneling and HTTP tunneling, NAT traversal using ICE, STUN, TURN and Port prediction algorithm; and acts as media relays for adaptive peer-to-peer media transmission for the best QoS. The PsipTN Edge Server Network also is responsible for PSTN origination and termination services for VoIP related applications.

PsipTN provides complete BOSS (Business and Operation Support System) layer which provides customer care, billing, monitoring, configuration, provisioning and other OSS related support needed to ensure smooth integrations with any applications resident on the PsipTN.
