OSPrey Route Server   Download

The OSPrey server is a feature rich, high performance routing and CDR collection server for VoIP networks. The OSPrey server may be deployed as a external route server, or service control point (VoIP SCP), for multiple softswitches or session border controllers.  Or, the OSPrey server can be deployed as a VoIP peering server for secure access control, routing and CDR collection for direct peer to peer traffic among anonymous VoIP networks.

Key Features:

  • Comprehensive routing features for VoIP devices and subnets

  • Jurisdictional routing: Inter-state, Intra-state, Local, Inter-LATA, Intra-LATA and international

  • Special routing for calls with invalid ANI or calling number

  • Trunk group routing and routing based on gateway or softswitch partitions

  • Time of day and day of week routing

  • Routing by percentage based load balancing

  • Routing based on calling number for intra-state routing or customized local calling areas

  • VoIP routing based on any combination of rank ordering and load balancing

  • Called and Calling number translation based on DNIS, ANI, time of day, day of week

  • Bar calls based on any combination of DNIS, ANI, or IP address of source or destination

  • Call gapping

  • Host Number Portability Database

  • Routing based on Local Routing Number (LRN) or dialed telephone number

  • Auditing module available

  • Real time CDR collection from source and destination networks

  • Automated call blocking based on credit status

  • Support for queries to external route servers based on OSP or ENUM

  • CALEA module for secret diversion of calls based on any combination of ANI, DNIS, source IP or destination IP address.

  • Support for Cisco GKTMP protocol.

  • X.509 certificate authority

  • Messages encrypted using SSL / TLS

  • Broad Platform Support: Cisco, Asterisk, OpenSER, SIP Express Router, Stratus, Veraz, and others.

  • The OSPrey sever can be combined with NexOSS which offers the additional features of Least Cost and Grade of Service routing, QoS reports and alerts, Traffic Analysis reports, CDR rating and hourly billing and profitability reports - by customer and route.

OSPrey as a Route Server (VoIP SCP)

OSPrey may be configured as a route server and CDR collection server for a VoIP signaling device such as a softswitch, gatekeeper, SIP proxy or session border controller.  In this type of deployment, the OSPrey server provides the intelligence and scale for routing features that cannot be provided by a VoIP signaling device.  For example, since many VoIP signaling devices cannot support a large least cost routing table, this function is off-loaded to the OSPrey server which can support a routing table with 50,000,000+ destinations.  An example call scenario for this type of deployment is described below.  A single VoIP Switch is shown in the diagram, but typically multiple VoIP signaling platforms of different types could are served in parallel by one or more OSPrey servers sharing the load. 

VoIP Route Server

1.   A call originates from the Source VoIP Device and is routed to the VoIP Switch.

2.   The VoIP Switch sends a routing query to the OSPrey server.  The OSPrey performs a route lookup and returns a list of IP addresses of devices which can complete the call to the called number.  The OSPrey can translate the calling or called number as needed.

3.   The call is routed from the VoIP Switch to the Destination VoIP Device which completes the call.

4.   At the end of the call, the VoIP Switch sends a call detail record to the OSPrey server.

OSPrey as a Secure Peering Server

The OSPrey server may also be used as a secure peering server for authorizing and accounting for direct peer to peer communications between anonymous VoIP networks.  For direct peering, each VoIP peer must enroll with the OSPrey certificate authority to obtain the OSPrey server's public key.  Also, the OSPrey server signs the certificate request from each VoIP device.  This feature requires the certificate authority and security features available only on the Solaris version of the OSPrey server.  The call scenario in the diagram below illustrates the OSPrey server being used as a peering server.

VoIP Peering Server

1.   A VoIP call originates from the Source VoIP Device.

2.   The Source VoIP Device sends a route query to the OSPrey server which returns a list of IP addresses of devices which can terminate the call.  Included with each address is a digitally signed peering token authorizing the call.

3.   The Source VoIP Device sends a SIP Invite or Q.931 call setup message directly to the destination peer.  The peering token is included in the SIP Invite or Q.931 call setup message.

4.   The Destination VoIP Device validates the peering token with the OSPrey server's public key.  If the token is valid, the Destination VoIP Device accepts the call.

5.   When the call is finished, both the source and destination devices send call detail records to the OSPrey server.

ClearIP Peering Engine

The ClearIP Peering Engine is an OEM version of the OSPrey server for vendors who want a private label, full featured, commercial OSP server.
