In the following scenario, combine control and signaling on one subnet and data on another subnet. This network interface scenario assigns a second address to the CPU (in addition to the one assigned at BootP) for H.323 or SIP Signaling. When configuring H.323 or SIP Signaling, select 10.10.25.2 for the IP Address in the H.323 Signaling or SIP Signaling pane.
Note: that this scenario does not inter-operate with Cisco Gatekeepers.
