Quarantined Phone Status

Last Updated : Sep 22, 2023 |
Prolog information
This menu displays phones that have previously been registered but are now blocked from re-registering because another phone has subsequently registered using the same registration parameters. This blocked state is called quarantined.
  • For example: When a user who has an already registered on one phone then registers on another phone using the same parameters, the previous phone may automatically attempt to reregister itself. In that case, even though the previous phone is presenting correct registration details, its registration is blocked and it is quarantined.
  • The default quarantine time is five minutes. However, if the phone keeps on trying to reregister, its quarantine time is extended. Most phones eventually cease attempting to automatically re-register.
  • Quarantining is treated separately from blacklisting since the phone has been previously registered with correct authentication parameters.
  • Quarantining honors the restrictions for simultaneous telephony device use by users. For example, such users can simultaneously register one physical deskphone (including SIP, H.323 and DECT), one desktop PC VoIP client, one mobile VoIP client and one WebRTC client.
