IP Office supports SIP voice calls through the addition of SIP lines to the system configuration. This approach allows users with non-SIP phones to make and receive SIP calls.

Deleting a SIP line requires a “merge with service disruption”. When the configuration file is sent to the system, the SIP trunk is restarted and all calls on the line are dropped.

This type of configuration record can be saved as a template and new records created from a template. See Working with Templates.
