The Voice engineer in your company need to change IP address destination on SIP-Trunk on near side?

Resetting the trunk on the near side applies the updated destination IP address configuration locally where the change was made. Only the near-side endpoint needs to reload its trunk settings, and doing so activates the new IP without affecting the far-side configuration or causing unnecessary service interruption.

Resetting the far side is unnecessary because the IP address change was made on the near side, and the far side has no modified configuration to reload.

Resetting both sides is excessive and causes unnecessary disruption, as only the near side where the configuration change occurred requires a reset.

Restarting the Call Manager service is a broad, high-impact action that affects all active calls and is not required for a targeted SIP trunk IP address update.
