HUAWEI IP Phone 7920 supports sequential registration:

registration interval. If the active SIP server fails, the IP phone registers with the standby SIP
server. If the standby SIP server also fails, the IP phone registers with the local SIP server.
Services are interrupted during the SIP server switching. After the IP phone registers with a
SIP server successfully, its services become available again.
