Limiting SBC Call Duration

You can configure the maximum allowed call duration (in minutes) per SBC call. If an established call reaches this user-defined limit, the device terminates the call. The feature ensures that calls are properly terminated, allowing available resources for new calls. The following procedure describes how to configure the feature for all calls (globally). To configure the feature per specific calls, use IP Profiles (IpProfile_SBCMaxCallDuration).

To configure maximum call duration:
1. Open the SBC General Settings page (Setup menu > Signaling & Media tab > SBC folder > SBC General Settings).
2. In the 'Max Call Duration' field (SBCMaxCallDuration), enter the maximum call duration per SBC call:

3. Click Apply.
