The NSF, the country's main opposition bloc, cautiously welcomed the offer.
Abdel-Ghaffar Shukr, a NSF member and vice-chairman of Arab Research Center, said the Front would not join the national dialogue unless it is certain about its topics and the participants.
Shukr said "Egyptians are fraught with anger because people's demands of better living condition, freedom, social justice and human dignity have not been met, although two years have passed."
The NSF demanded Morsi to sack the current cabinet, appoint "a national salvation government" and form a panel to amend the recently-drafted controversial constitution, threatening to boycott the upcoming parliamentary elections if their demands were not met.
In a recent statement, the opposition bloc held the president responsible for the victims of recent protests, urging mass peaceful demonstrations next Friday to halt the constitution and plan for early presidential elections.
However, Amr Darrag, a member of the executive bureau of the Muslim Brotherhood's Freedom and Justice Party, said that "The Defense Council's invitation for a comprehensive national dialogue is the best solution for the current crisis."
Darrag described the opposition's persistence on constitutional amendments as "a waste of time," arguing that suspending national dialogue over the constitution issue was "unrealistic."
