"The hotline has been operational since yesterday (Sunday)," the official said on condition of anonymity but noted that the presidents have not used it yet.
"It is designed to help communication among the three capitals in times of crisis," the official added.
The presidents of Afghanistan and Pakistan are due to hold talks in Turkey on Tuesday and Wednesday in a bid to resolve a row after Kabul claimed an attack against its spy chief was planned in Pakistan.
The assassination attempt on National Directorate of Security (NDS) chief Asadullah Khalid was carried out Thursday by an attacker who claimed to be a Taliban peace envoy but had a bomb hidden in his underwear.
Afghan President Hamid Karzai did not directly blame Pakistan for the attack but said the Taliban alone would not have been able to carry out the bombing and that "bigger hands were involved".
The Pakistani foreign ministry rejected the claim and said it was ready to help investigate what it called a criminal act.
Turkish President Abdullah Gul will host his Pakistani counterpart Asif Ali Zardari and Karzai during a dinner on Tuesday.
The summit in Ankara will be the seventh in Turkey, a Nato member, since the regular consultation mechanism was established in 2007 to encourage both countries to cooperate against extremism.

Yeah the 3 of them got together and noticed they all had the latest version of the iphone - decided to call it a "hotline".
Peace is unachievable with the two corrupt and powerless presidents Afghanistan and Pakistan. Talks should be held between Dostam, Kayani and the Americans. These are the guys running policy in both the countries.
These all talks,lines and efforts will serve USA/NATO purpose to prolong their stay.Now Iran,China and Russia will sort out AF-PAK because these two have no self respect,nothing will change much.
This won't stop the Afghans from tossing empty smears on Pakistan without evidence because they absolutely must do that to divert attention from their own failure to keep their house in order. Turkey, Pakistan and Afghanistan formed a joint investigative commission to get to the bottom of Burhanuddin Rabbani's assassination but a year later it reached no conclusion but the Afghans still blame that incident on Pakistan even though the only evidence they presented was a single A4 sized sheet.
