I have installed 3CX on to multiple Windows 2016 Servers all behind a sonicwall but they all failed on detecting SIP ALG, and testing port 9000 full cone test failed, although all other ports pass. I have followed the 3CX sonicwall guides to the letter, I have modified them to suggestions made by others on these forums but nothing makes my firewall check go green. I saw back in Dec 18th 2018 that there was an issue on 3CX side for SIP ALG, is this the case today?
Any help / suggestions please.
