A powerful rou ng server
for your VoIP network
The OSPrey server is a feature rich, robust rou ng
and CDR collec on server for VoIP networks. The
OSPrey server may be deployed as an external route
server for mul ple so switches or session border
controllers.
OSPREY AS A ROUTE SERVER
OSPrey may be configured as a route server and CDR collec on server
for a VoIP signaling device such as a so switch, gatekeeper, SIP proxy,
or session border controller. In this type of deployment, the OSPrey
server provides the intelligence and scale for rou ng features that
cannot be provided by a VoIP signaling device. An example call scenario
for this type of deployment is below. A single VoIP switch is shown but
typically mul ple VoIP signaling pla orms of different types can be
served in parallel by one or more OSPrey servers sharing the load.
1. A call originates from the Source VoIP Device and is routed to the
VoIP Switch.
2. The VoIP Switch sends a rou ng 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. OSPrey can translate
the calling or called number as needed.
3. The call is routed from the VoIP Switch to the Des na on 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 accoun ng for direct peer-to-peer
communica ons between anonymous VoIP networks. For
direct peering, each VoIP peer must enroll with the OSPrey
cer ficate authority to obtain the OSPrey server’s public key.
Also, the OSPrey server signs the cer ficate request from each
VoIP device. The call scenario in the diagram illustrates the server
being used as a 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 that 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 des na on peer. The peering token is
included in the SIP invite or Q.931 call setup message.
4. When the call is finished, both the source and des na on
devices send call detail records to the OSPrey server.
OSPREY AS A HOST FOR NPAC
OSPrey can be a simple, low cost solu on for hos ng the US
number portability database within your network. The server
automa cally stays synchronized with the US Number Portability
Administra on Center (NPAC) to ensure your network has a near
real- me copy of the NPAC.
