Reliable SIP‑based interconnection
With interconnection traffic between interconnected networks you can connect to our telecommunications network and mobile network services. This enables you to offer Telia's customers access to your services and as well provide your own subscribers with connectivity to Telia’s services and those of all other telecommunication companies operating in Finland. We provide operators in Finland with high‑quality interconnection solutions and communication connectivity.
Domestic interconnection traffic is implemented using SIP connectivity (Session Initiation Protocol) with the SIP‑I extension, which is used to establish, maintain, and terminate services such as voice calls, video conferencing, and instant messaging in the network.
