Mr Bush planned to make a brief statement about the attacks upon his return to the White House later on Saturday after spending the holiday weekend at the retreat in Maryland.
Among those participating in the secure video-teleconference were Secretary of State Condoleezza Rice; David Mulford, the US ambassador to India; Paul Folmsbee, consul general at the US consulate in Mumbai, India; and members of Mr Bush's national security team.
'President Bush thanked our ambassador and our consul general for all the work they've done to help Americans affected by the terrorists,' White House press secretary Dana Perino said.
President-elect Barack Obama called Indian Prime Minister Singh on Friday night to offer condolences and said he was monitoring the situation.
The terror rampage that left at least 195 people dead, including six Americans, in India's financial capital ended Saturday when commandos killed the last three gunmen inside a luxury hotel.
A previously unknown Muslim group with a name suggesting origins inside India claimed responsibility for the attacks. Indian officials said the sole surviving gunman was from Pakistan and they pointed a finger of blame at their neighbor and nuclear rival.
