The osp module enables SERi [1] to support secure, multi-lateral peering using the OSP standard defined by European Telecommunications Standards Institute (ETSIi [2]) (TS 101 321 V4.1.1). Open Settlement Protocol uses Public Key Infrastructure (PKI) services to enable, secure peering among anonymous peers. OSP is an ETSI standard and enables VOIP networks to exchange billing, Quality of Service (QoS), and routing information.

The SER osp module will enable your SER to:

Send a peering authorization request to a peering server

Validate a digitally signed peering authorization token received in a SIP INVITE message

Report usage information to a peering server
