The ending '-at' turns the word stem 'Telefon' (telephone) into a noun that describes a single event or process. So it refers to a single telephone conversation.

Especially in formal or business contexts, 'Telefonat' (phone call) is often combined with the verb 'führen' (to conduct): 'ein Telefonat führen' (to make/conduct a phone call).

To name the person you are speaking with, use 'mit' + dative. To name the reason, use 'wegen' + genitive.

conversation
Gespräch and Telefonat both refer to a spoken exchange, but only Telefonat specifies the telephone as the medium. Gespräch remains neutral about the medium. Use Telefonat when the fact that it was by phone is important, and Gespräch when the exchange itself is the focus.
