SIP interconnect
A simple, secure way to connect
Exchange wholesale voice traffic with Altaris through a carrier-to-carrier SIP interconnect, and reach the United States and Canada over premium Tier-1 routes.
Get connectedOverview
Before your traffic can reach our Tier-1 routes, our networks need to be connected. Altaris exchanges traffic with its partners through a SIP interconnect: a direct, carrier-to-carrier connection built for wholesale voice.
Our aim is to make connecting with us as straightforward as possible, so you can move from first conversation to live traffic without unnecessary complexity.
What is a SIP interconnect?
SIP (Session Initiation Protocol) is the standard technology used to set up and manage voice calls over IP networks. A SIP interconnect uses SIP to link two carrier networks so they can exchange voice traffic directly.
In practice, this means your network sends calls to ours over the interconnect, and we carry them onward over Tier-1 routes to fixed and mobile numbers across the United States and Canada.

SIP interconnect vs SIP trunking
The two terms sound similar, but they describe different services.
SIP interconnect
A SIP interconnect connects two carriers so they can exchange wholesale voice traffic. It is a network-to-network relationship between businesses in the voice industry.
SIP trunking
SIP trunking connects a business phone system, such as an office PBX, to a voice provider. It is a retail service, and it often comes with phone numbers included.
Altaris offers SIP interconnects only. We do not provide SIP trunking, DID numbers or dialer services, because our focus is purely on wholesale voice.
