Hierarchy Level


When there are multiple users behind SIP proxies at either end of an SRX, with multiple SIP calls ongoing between the users via these SIP proxies and through the device, and all SIP traffic is using the same 5 tuples, this results in a single SIP control session on the device, referred to as SIP bulk call or a SIP "fat" session.

To load balance such SIP calls on the device, the command set security alg sip bulk-call-mode can be used. When enabled, SIP call ID is used to identify and distribute the SIP calls among different SPUs instead of the regular 5 tuples, resulting in individual control sessions for each SIP call.
