Telia allows service providers operating public telephone or mobile network whose network meets the Telia interconnection requirements to connect their network to Telia's telephone and mobile network.

In telecommunication interconnection means that different carrier's networks are connected to enable mutual traffic. It allows a customer of one network to communicate with a customer of another network.

An interconnection agreement is required, which basically means a corporate agreement between telecommunication organizations to connect their networks and exchange traffic.

Telia enables call origination, call termination and call transit to service providers operating a public telephone or mobile network with whom an interconnection agreement has been signed.
