USING UCMRC WITH HA
If the user has purchased UCMRC plan with HA, the GDMS web page can show the UCM with HA status
“Host” or “Spare”.

Switching UCMRC Role in HA
Prerequisites:
• Both UCM must have UCMRC plan with HA feature purchased on GDMS.
• UCMRC service has been successfully delivered to both UCM.
Implementations:
• The call service is provided by GDMS and the active UCM.
• When the active UCM A is in faulty condition and has triggered switchover, the standby UCM B will
take over and becomes active. UCM B will send switchover command to GDMS and notify GDMS
that call service will be provided by UCM B and GDMS afterwards.
Notes:
1. With UCMRC, after the UCM are configured with HA, UCM will notify its HA role to GDMS. System
admin does not need to designate HA role for UCM on GDMS.
2. On GDMS, system admin can still remotely access and operate each UCM in HA. However, the
configuration on the standby UCM limited because it synchronizes data from the active UCM
regularly in HA backup process.
3. The PBX providing service is the active UCM. However, GDMS will always assign the domain name
for Remote Connect service based on the primary UCM as configured initially.
