Yes – we have created tools which use the REST API/web interface of phones (and base stations) to force immediate re-registration following a failover of the cluster. This solution is implementation specific however (make and model of phone, where phone IP data is stored, etc), so please contact Telium professional services who can design a solution for your specific needs.
This tool should be placed into Asterisk post-start event handler (in HAAst), which will cause the nurse phones to immediately reconnect to the active peer following cluster failover.
