Deployment Architecture Example

The figure below depicts the architecture of a sample deployment of primary and backup SIP Servers, Active-Active Resource Manager pair, and the BIG-IP LTM, in which:

• BIG-IP LTM provides a single Virtual IP address for SIP phones and Media Server.
• The pair of SIP Servers configured in Hot-Standby mode is located behind BIG-IP LTM and the actual IP addresses of the primary and backup SIP Servers are not exposed to phones or Media Server components.
• All SIP entities in the environment—phones, SIP Servers, Resource Managers, MCPs—can use TLS for SIP signaling if configured.
