Cuba and the United States have re-established direct telephone communication links for the first time in 15 years.
"The re-establishment of direct communications between the United States and Cuba contributes to providing better infrastructure and better communications quality between the people and our two countries," the company Etecsa said in a statement, adding that the link would initially be only for telephone calls.
Etecsa's US counterpart, IDT Domestic Telecom, said: "Ultimately, the agreement will make it easier and more affordable for our customers to call friends and family in Cuba."
The agreement is the first signed since the two countries announced in December they would re-establish diplomatic relations.
