A Palace officials confirmed on Wednesday that President Rodrigo Duterte and National Democratic Front (NDF) chief political consultant Jose Maria 'Joma' Sison talked over the phone at dawn last Tuesday.
Presidential spokesman Ernesto Abella said President Duterte and Sison agreed to pursue the peace process.
"It did go on. It went through at about 3 a.m. dawn of that particular day. From the sources, it was a warm conversation between old friends," Abella said.
"But there were no details, there were no political issues that were covered. However, both were agreed that the peace process must move forward," he added.
In his Facebook post, Sison confirmed the conversation which he described as "friendly and productive."
Sison said the unilateral ceasefire declarations of the GRP and NDFP will stand during the Christmas and New Year holidays.
He added: "Bilateral ceasefire agreement and the amnesty and release of the political prisoners listed by the NDFP can be discussed and agreed upon before, during and even after the third round of formal talks in Rome from January 18 to 24."
