Multi Service Business Gateway (MSBG, SBC with Telecom Cards) is not Supported.When using SBC VMs, creating the VMs both VMs have to have the same number of interfaces since first boot, same exact number Ethernet physical interfaces, number assignment (Eth0, Eth1.) and default gateway configuration.

The Backup Link can be either a Second Dedicated Link or one Ethernet Interface connected to an internal network subnet, where both servers can reach each other on the same Subnet via a Multicast link The cluster requires one Dedicated Ethernet Network Link between both SBC Appliances and one Ethernet Network Link as a Backup Link.These are the minimum requirements for proper operation of High Availability on the Sangoma SBC, There is a Dedicated Network for the purpose of a "heartbeat" which is used to monitor the health and status of the other SBC Server in the cluster, as well as copy the configuration to the Secondary server within the SBC application. SBC HA cluster implementations add redundancy to eliminate single points of failure, including multiple network connections and Call Flow applications. SBC HA clusters are often used for critical Trunking and Remote Phone applications on a Carrier network, Enterprise Network, and various VoIP business applications. These Floating IPs allow for the Failover to occur, when the Master Node fails, the Salve Node becomes the Master Node and take Active control of the Floating IPs. These Floating IPs are common/shared on both Primary and Secondary SBCs as the common point of entry and exit for SIP Call Flow. The Sangoma SBC makes use of Floating IPs, these are created for each of the network segments (WAN, LAN, DMZ) connected to the SBCs. As part of this process, the SBC application shares the same configuration and uses common "Floating" IP Addresses to create a singular SBC application. HA resolves this situation by detecting hardware, software, and network faults, and immediately migrates the SBC application on another SBC Server without requiring administrative intervention, a process known as Failover. Without clustering, if a SBC Server crashes, the SIP Trunking, Remote Phone or other Call Flow applications will be unavailable until the crashed SBC Server is fixed. The SBC operates by using specially designed high availability software to harness the redundant SBC Server to provide continued service when system components or network connectivity fail. High-Availability Sangoma SBCs is a group of 2 SBC Servers that support the SBCÂ application that can be reliably utilized with a minimum of down-time. The migration period is very quick, typically lasting only 10-15 seconds. During the migration process, established calls drop and no new calls are processed. Also, allowing the system administrator to configure both servers as the primary one and copy the configuration to the secondary server with a single command. The High Availability component provides the ability to join two SBC Servers in an Active/Passive cluster with automatic migration of service in case of a hardware or network failure.
