Troubles with follow me to mobile in two pbx structure

Hi guys, I have next configuration.
Two freepbx servers(pbx1, pbx2) connected with trunk. Only one (pbx1) have provider trunk to the city. If I call from pbx1 to pbx2 to extension with redirect on mobile phone call returned to pbx1 so trunk doesn’t know what to do. Is it possible to configure these scheme to work, o i need to do providers trunk on each server.
