Use this flag to allow the usage of different IP-Port as contact for each active registration towards Cisco Unified Communication Manager (CUCM). The SBC uses either an independent media port range configured per IP Trunk Group (IPTG), or a new port from the system-wide media port range if no independent media port range is configured per IPTG.

The SBC supports this feature when:

  • Only one SipSigPort is configured on egress.
  • IP address of SipSigPort is the same as the associated LIF IP.
Note

Disable usePortRangeFlag flag before performing the Live Software Upgrade (LSWU).

 

Feature limitations and restrictions:

  • This feature is supported only for UDP.

  • Disable the flag passCompleteContactHeader to use this feature.

  • Do not use this feature if two Interfaces are configured on the same Interface Group.

  • Disable this flag before performing LSWU.
