Salisu is yet to win a cap for his country after turning down previous call-ups in order to concentrate on his career with his Premier League club but met with Ghana Football Association officials this year over his availability for the World Cup finals in Qatar.
Brighton and Hove Albion right back Lamptey is included after switching his allegiance from England, where he was capped at junior level, while Williams has also agreed to play for Ghana despite a single cap for Spain in a friendly in 2016.
The Athletic Bilbao striker last season broke the Spanish league record for the most consecutive appearances and has extended it to an unbeaten 237.
Ghana take on Brazil in Le Havre on September 23rd and then Nicaragua in Lorca, Spain on September 27th as they round off preparations for Qatar, where they have been paired with Portugal, South Korea and Uruguay in Group H.
Ghana coach Otto Addo also named two former German youth internationals Stephan Ambrosius (23) and Ransford-Yeboah Konigsdorffer (20), who the Ghana FA also said had switched international allegiances.
