Foreign Minister Mohammad Javad Zarif made the announcement in a phone call of his Azeri counterpart Jeyhun Bayramov on Thursday, IRNA reported.
During the conversation, Bayramov briefed Zarif on the latest developments of the Nagorno-Karabakh tension.
The Iranian top diplomat reaffirmed Iran's principled stances on Nagorno-Karabakh issue emphasizing the significance of Azerbaijan's territorial integrity.
The two foreign ministers also stressed the importance and major role of the regional initiative in resolving the several-decade-old crisis.
Clashes over Nagorno-Karabakh – where Armenia-backed separatist fighters are battling Azerbaijani forces – have been largely confined to areas in and around the region since a fresh outbreak of fighting started last month.
It has originally started in 1988 and led to a military conflict in 1992.
The heavy clashes erupted late last month, with both sides blaming the other for the biggest outbreak in violence since a 1994 ceasefire left the status of Nagorno-Karabakh in limbo.
Iran has repeatedly expressed readiness to help settle the escalating tension which has become one of the most enduring problems left after the fall of the former Soviet Union (USSR).
On October 10, President Hassan Rouhani told his Russian counterpart in a phone call, that Iran “is ready to assist and cooperate in resolving the dispute between Azerbaijan and Armenia through negotiation based on international law and with respect for the territorial integrity of the countries.”
Two days ago, Armenian and Azeri foreign ministers through Russia's mediation agreed on a ceasefire but the violation of the ceasefire suggests the truce agreement is fragile.
