Your SIP providers may change their IP address for your registration without prior notice. To avoid inaccessibility, configure Kerio Operator to periodically resolve domain names and renew the registration.
- In the administration interface, go to Configuration > Call Routing > Interfaces and routing of incoming calls.
- Select an SIP interface and click Edit.
- Go to the SIP Details tab.
- Select the Periodically resolve domain names option.
- Click OK.
Confirmation: Kerio Operator now periodically resolves domain names of your SIP provider and renews your registration whenever the IP address changes.
