The Toll-Free Exchange is the first and only routing platform to directly connect Responsible Organizations to each other via authoritative routing information, validating the rates and destination of the call by looking up the dialed toll-free number in the Somos SCP. The power of the Toll-Free Exchange is that a single SIP interconnection to the Toll-Free Exchange can immediately connect a RespOrg to hundreds of other participating RespOrgs, bypassing the Public Switched Telephone Network (PSTN) and the numerous interconnections that it requires for call completion to occur. This reduces a RespOrg’s cost and increases revenue on each toll-free call.
