5. Define the group metric for the server group. Because SIP load balancing is performed based on
Call-ID, only the minmisses metric is supported to ensure persistency.
6. Define the health check for the group. Configure SIP PING request health check which is
specifically developed for SIP-enabled servers.
7. Configure a virtual server for Layer 4 SIP load balancing.
8. Configure the SIP service 5060 for Virtual Server 1.
9. Enable SIP SLB.
10. Enable DAM.
11. Enable UDP load balancing
12. Increase the timeout for idle sessions.
Note: SIP sessions are quite long and data may be flowing while the signaling path is idle.
Because Alteon resides in the signaling path, Radware recommends increasing the real server
session timeout value to 30 minutes (Default: 10 minutes).
When the call terminates with a BYE command, Alteon releases the session entry immediately.
13. Enable server and client processing at the port level.
