SIP and call persistence specifications
The SIP server load balancing has the following specifications:
• By default, server selection is persistent on Call-ID.
• Pass-through SIP traffic from real SIP servers to SIP clients gets translated. The Virtual ADX
replaces the source IP (SIP server real IP) with Virtual IP (VIP).
• The Virtual ADX does not modify any of the SIP header fields.
• The Virtual ADX does not perform SIP-aware NAT.
• This implementation is based on RFC 3261.
NOTE
The Virtual ADX SIP SLB is not implemented as a SIP proxy server, but rather as a load balancer of
proxy or registrar traffic.
