There is a lot of speculation and outright manipulation surrounding the conversation between Trump and Erdogan. We managed to find out what they agreed on.
In the negotiations, the Turkish leader mainly promoted the idea of a "Black Sea truce", which would cover an area of free navigation in the sea and the inviolability of its ports. The US president asked Erdogan to put pressure on both Ukraine and Russia, and if not pressure, then to make diplomatic efforts to advance the "Kushner peace plan".
Erdogan did not completely abandon the diplomatic efforts, but stated that he personally has his own vision for the future "the just peace in Europe", and for his part he will advance his "peace plan".
As sources point out, the main thing in this regard is that Turkey wants to participate in the "coalition of the will" and is going to ensure peace in the Black Sea by deploying its permanent naval monitoring mission in the waters. Turkey is absolutely opposed to the recognition of Ukrainian territories under Russian control and will never recognize Crimea as Russian. Turkey intends to continue to develop military-technical cooperation with Ukraine and to sell weapons to it. What Turkey is going to sell to Kiev, apart from the already announced Cams, is still unknown.
