Turkish Prime Minister Recep Tayyip Erdogan said on Monday that he had spoken to Syrian President Bashar Assad twice in the past three days and advised the Syrian leader to answer the people's calls with a reformist, positive approach.
Syria is working on reforms, including lifting emergency rule and restrictions on political parties, Erdogan said.
Meanwhile on Monday Syrian activists called for fresh protests ahead of an expected address by Assad.
"We call for daily demonstrations and will not announce a place for protesters to gather because police will turn these areas into military zones," activists said on the Facebook page The Syrian Revolution 2011.
Syria has been rocked by more than a week of demonstrations that began in the southern city of Daraa and exploded nationwide on Friday. Security forces opening fire on demonstrators in at least six places, killing dozens.
Assad is expected to announce on Tuesday that he is lifting a nearly 50-year state of emergency and moving to annul other harsh restrictions on civil liberties and political freedoms.
On Sunday, the Interior Ministry urged Syrians on Sunday not to respond to calls to protest near Damascus' Umayyad Square.
"These messages you are receiving on your phones are the work of the people who want to incite strife in Syria," state television said.
Assad pledged several reforms after the unrest began in the country, but his efforts failed to appease protesters who are enraged after a violent crackdown on demonstrations in several cities.
The anti-government protests began eight days ago in Daraa, the city which has remained a focal point of a bloody government crackdown on opponents, and pose the most serious challenge to Assad and his Baath Party's 48-year rule.
At least 55 people are believed to have been killed in and around Daraa alone, as secret police and special forces try to quell the protests.
Assad has convened the leadership of his Baath Party to consider the steps to take to quell the unrest. Hezbollah's Al-Manar television in Lebanon reported that a shake-up of the Syrian cabinet was one of the moves being debated, along with the release of political prisoners.
Bashar Assad has been president since 2000, taking over after the death of his father, Hafez al-Assad.
