In 2005, MTT was mainly focused on expanding its own network throughout Russia. 44 local switching centres were launched that year; MTT was able to connect regional operators to MTT’s transit network in all Russian regions. That year the nationwide network infrastructure was completed. The network was built based on state-of-the-art equipment that facilitated the addition of new services. In 2005, all mobile operators connected their networks to MTT.
The new stage of the company’s development was characterized by upgrading the network and by getting a “long-distance operator” license in order to provide service to end users, i.e. fixed-line subscribers. By September 2005, MTT was completely ready to render long-distance service in the whole territory of the Russian Federation. While preparing to render international voice service as an international operator, MTT had signed a set of agreements with the largest international and Russian telecom companies. Among the voice traffic transmission partners of MTT were MCI International, T-System, TeliaSonera and TDC Teledenmark; new agents in Russia appeared: MTT signed a partnership agreement with Zebra Telecom. In December the company received carrier selection codes and telecom network terminal category indices needed to provide access to long-distance and international voice service rendered by Multiregional TransitTelecom JSC.
In 2005, WLAN roaming (roaming in Wi-Fi networks) an internationally popular service with great potential, was launched. The organizational and technical interaction between operators within this service was tested within a pilot area organized by MTT together with KomStar-United Telesystems, VympelCom, PeterStar and RTKOMM.
