SIP Redirect or Proxy Server?

The iNode can be configured both as a SIP Redirect Server and a SIP Proxy Server. For most services, a SIP Redirect Server is sufficient and perhaps the better choice, as it is more efficient for lookup transactions.

However, sometimes, the more complex SIP proxy server is needed. This could be the preferred choice for a VoIP service provider due to architectural or interoperability reasons. All services can be produced on a SIP proxy server. It is required when forking, as in the case of for example Invite's service One Number.
