SIP Trunk Group Supported List

Sip Trunk Group Exempted List

Trunk Groups with CALEA-compliant lawful intercept (LI) rules may intercept a call on each leg of the call. To prevent this, you can identify a specified leg of a relevant trunk group (TG) to either a Supported TG List, or to an Exempted TG List, assuring that calls are only intercepted once.

These are mutually exclusive lists, and entries can only appear on one list, never both. Entries on these lists are leaf references to SIP TGs that apply across the entire system, and will apply to all addressContext objects and zones.

Select pre-configured trunk groups from the drop-down menu.
