I’m new to asterisk. My asterisk version is 22.214.171.124. I found similar post in this forum, but the recommended solutions did not work for me. I have disabled the SIP ALG in the firewall (FortiGate). Please find the below debug when I make a test call from 0123534328 to 5612 extension (DID: 043761112).
