Hi i'm having an issue with phones (iphones/softphones/handsets) getting outbound connection from my office to my 3cx selfhosted on AWS. I have a sonicwall in the office and it seems to be blocking connection/provisioning to the AWS 3cx server. Although i can telnet to SIP ports, can access the management portal remotely. The 3cx firewall checker is all green ticks and if i use a different internet connection that the office the phones connect fine. So i know the 3cx AWS setup is ok and fairly confident the office sonicwall or something is blocking outbound connection to the remote 3cx. Have had a look through the sonicwall and there are no outbound rules blocking anything. LAN > WAN is Allow All. I even put in a specific rule for LAN > Remote 3cx Allow All. any ideas?
