The LORD Himself is the One that Calls His Prophets; and Sends them (The Genuine Prophets of The LORD) to Serve Him. They don't "Call" themselves.
Zechariah 1: 2-4 ‘“The LORD has been very angry with your fathers. Therefore say to them, ‘Thus says The LORD of hosts: “Return to Me,” says The LORD of hosts, “and I will return to you,” says The LORD of hosts. “Do not be like your fathers, to whom the former prophets preached, saying, ‘Thus says The LORD of hosts: “Turn now from your evil ways and your evil deeds.”’ But they did not hear nor heed Me,” says The LORD.”’
