Two Yeastar IP-PBX could be optimized for use as a failover system which could provide rapid failover in the event of system failure. Once the active server failure is detected, all the telephony would be switched to the standby server automatically. Thus the downtime was kept to an absolute minimum to ensure the normal operation of all the functions for users.
You are in need of instant communications with your customer, but the whole telephone system suddenly goes down without any signs. Don’t worry. Hot standby is waiting in the background and will connect you in seconds, avoiding any business loss caused by unexpected server failure.
