Ghana Telecom would soon complete the installation of a 35,000-line capacity Alcatel Switch System in the Kumasi Metropolis.
The new switch system would ease telephone congestion and increase subscriber from 22,000 lines to 55,000 lines.
Nana Kwakye Tannor, Ashanti Regional Director of Telecom, said the installation started about three months ago.
"The project is one of the major expansion works by the Company since 1994 and when completed additional 23,000 lines would be available for distribution."
Nana Tannor attributed the congestion to the constant use of the lines by subscribers, proliferation of communication centres and the effect of the Internet service operators in the Metropolis.
