1. BCS requirements

System requirements

• Two identical Waves. BCS requires two identical-model Waves. This means that if the primary Wave is a current-model ISC3 IP 2500, the secondary Wave must also be the same model ISC3 IP 2500. Similarly, if the primary Wave has an MRM-C installed, the secondary Wave must also have an MRM-C, and so on for all installed hardware components.

The Waves must both be on the same level of Wave software, including Hotfixes.

• Supported Vertical Edge IP phones:
• Vertical Edge IP 5000i phones:
• Vertical Edge IP 5000i-LLCDG large LCD screen phone
• Vertical Edge IP 5000i-24G 24-button phone

Other phones are not guaranteed to failover in a timely fashion, or at all.

• SIP trunking. BCS requires SIP trunks—analog and digital trunks will not failover. Your ITSP must provide SIP trunking service to any IP address that correctly registers with them. The primary and secondary Waves each have a separate, unique IP address.

Multiple ITSPs can be used for improved reliability. You set this up on the primary Wave as normal for using two SIP trunk providers on one box, and configure outbound and inbound routing to use both sets of trunks (in order of priority). This trunk configuration passes to the secondary Wave at failover.

Software requirements

• Wave 4.5 or higher
• Wave Business Continuity Service license key for the primary Wave

Network requirements

• All devices must be on a single network. Both the primary and secondary Waves, all phones, and ViewPoint Desktop clients must be on the same routable network. The Waves do not have to be on the same site, but they cannot be separated by NAT.
• Your firewall must allow access for both Waves. The firewall for the network must allow port-forwarding of traffic for SIP trunking to both Waves (both inbound and outbound).
• ViewPoint Mobile requires two ports. ViewPoint Mobile already requires a single port to be forwarded for inbound and outbound traffic to the Wave. With BCS, two ports must be specified. This can be the same port on two different public IP addresses (for example, 65.0.0.1:50070 and 65.0.0.2:50070) or two different ports on the same IP address (65.0.0.1:50070 and 65.0.0.1:50071).
