Video Guides - High Availability - UCM6300
High Availability feature on Grandstream UCM6300 series/UCM6300 Audio series provides enterprises a reliable solution for PBX redundancy and failover support. In HA setup, there are two UCM with one UCM in “active” role and the other in “standby” role. The two UCM must be the same model and use the same firmware version. The data on the active UCM will be synchronized to the standby UCM in real-time manner and the standby UCM monitors active UCM’s running status regularly. When the active UCM runs into hardware or critical software issues, the standby UCM will take over immediately and become the active server. HA feature supports automatic call recovery for UDP point-to-point calls and conference calls, allowing enterprises to communicate and collaborate without the hassle of service interruption.

Is it possible to have HA with both UCM in separate locations, but directly connected via a switch port trunk mode

[@abdeljaibar6372]

Thank you for watching the video! The Straight-through Ethernet cable has to be directly connected on the end of each UCM.

[@KEMCINNIS]

I'm told by several sources this can not be done. The HA setup info in grandstream manual also states the devices must be in the same building, connected by a straight through ethernet cable. The only think I can think of is there is a latency tolerance in the HA software. Seems to me if one could increase that tolerance then one could have the units in physically separate locations. Here in Florida we have hurricane concerns and would ideally like to have a UCM in two physically distinct locations and

Is HA possible with the UCM6208?

[@abdeljaibar6372]
