Freepbx chan_iax2.c:3592 __attempt_transmit: Max retries exceeded to host XX.XX.XX.XX on

Heelo

Today my Freepbx 5.2.11 with Asterisk 1.8 crashed. I only see these multiple messages on the Logs. I have two boxes connected via an IAX trunk and both of them aare connected to the PSTN with T1/E1 cards. I cannot make nor receive outbound calls. Internal calls work just fine. Please Help!!!
