What is SIP?

SIP Trunks enable the end point's PBX (On-Premises Phone System) to send and receive calls via an IP network, such as the Internet or Private WAN. SIP trunks allow as many simultaneous calls as a number of channels provisioned.


Simple and quick provisioning through administration portal.
An option to set limits for international calls with the ability to stop all calls when a limit is reached or notify relevant contacts.
Utilise your investment and keep your current telephone system.
Keep your current telephone number.
Enterprise trunking and hybrid cloud, allowing customers to move the cloud at your own pace.

Pay as You Go

Commandacom's Cloud SIP option of 'Pay as You Go' is billed individually for each user. No flag fall, calls are charged per second. Inbound calls are charged per minute, and calls to internal services do not incur additional charges.

Fixed Monthly Cost

If you want peace of mind and an option to set fixed costs each month. Commandacom are able to bundle all calls to local and national fixed line along with mobile numbers, which also include New Zealand numbers.


High Availability PBX Support

Commandacom's Cloud SIP will allow customers to register multiple PBXs per trunk. This supports customers that have a pair of PBXs configured for High Availability in that the  network knows it can reach both devices at any time to send calls 24 hours a day.

Route Exhaustion

If your PBX or internet connection is down, you can easily select an external location for calls to be delivered to, and it auto switches on failures. Additionally, for customers with hybrid cloud, calls can be directed to users on Commandacom’s UCaaS solution.

Enterprise Trunking and Hybrid Cloud

Commandacom delivers its Cloud SIP service using what is known as enterprise trunking. This advanced configuration allows customers to add additional functionality to the PBX from the cloud. It also allows customers to combine cloud hosted PBX and UC with their existing PBX.  For example: while the head office still has a PBX, remote offices can access the same number range and in most cases, they can even dial internal extensions. This ability to run hybrid premise and cloud telephony allows customers to move to the cloud at their own pace..
