Business One SIP



The Business One SIP Plan is a Commander SIP Plan. Commander SIP services are basic phone lines, or channels, connected via the Internet, also known as VoIP or IP telephony. They are generally used to connect SIP capable phone systems or gateway devices to the telephone network. You can transfer your existing Office Phone service or activate a new service with Commander. A minimum of 2 SIP channels are required and single channels can be purchased after the minimum at the same rate. Commander SIP services are not available for resale or high-volume telemarketing. Commander is responsible in supplying these services to our customers and we have no other affiliation or relationship with our wholesalers outside of our wholesale agreements. Equipment is generally required to access the service. In the event of a power outage, your Commander SIP services will not work unless you maintain a back-up battery solution. This service has a 1-month, 36 or 60-month minimum term applicable.

The Business One Commander SIP Plan can be bundled with a Business One Broadband Plan to receive a bundle discount. You are eligible for a Business One Commander SIP Channel for $0 for every Business One Broadband Plan you keep active.

If you cancel your Business One Broadband Plan, transfer it away or change it to a different NBN plan, you will lose the $45, $42 or $40 (contract dependant) discount and start paying the full price for the Business One Commander SIP Channel.

You will receive a discount if you bundle more than 5 Business One voice services together on the same account. If you maintain between 5 and 9 active Business One voice services, you will receive $5 off each fully charged service.

This offer is applicable across Commander Phone, Commander SIP and NBN Business Line services. If the number of active Commander voice services falls below the minimum threshold of 5 or 10 services, the applicable discount is removed and services charged at the full rate.
