When in the deny new service state, Entity Links do not accept new incoming calls and Session Manager does not route outgoing calls over these links. Link monitoring continues over these links but no alarms are generated for the denied links.
When placing an Entity Link into the Deny New Service state, you can:
Take selected SIP Entities out of service for upgrades and repair without receiving numerous SIP Monitoring alarms.
Test alternate routing paths by denying the primary link Session Manager uses on a given route.
Deny selected links during a planned WAN outage.
