IP and transport layer validation

Last Updated : Feb 25, 2015 |

Session Manager performs the following validation checks when receiving a request from the network:

  • The far-end IP address matches the IP address of one of the SIP Entities configured in ‘Routing’ that have entity links with Session Manager. If a SIP Entity is administered with an FQDN instead of an IP address, Session Manager resolves the FQDN to an IP address while doing the comparison.

  • The transport on which the request was received matches the administered transport of one of the entity links associated with this SIP entity and the Session Manager. The Connection Policy of the entity link must be configured as trusted, otherwise Session Manager challenges the request.
