Solved Email and Phones

[Phil OE]

I am having trouble with both android and apple phones outside of the network being able to connect to make calls. Something also changed as the system is no longer sending voicemails to email. I did update to the latest version 16.0.8.9. When I test the smtp server I get 5.7.0 denied. Nothing on our system has changed.

Hi Phil,

Regarding the calls, you should run your firewall checker first, and the check your firewall port forwards to confirm they are still working https://www.3cx.com/docs/ports/

As for the SMTP test, it can also potentially fail if the PBX cannot access the internet, so both issues put together sounds like 3CX is having trouble reaching the outside world.

Guess that will be an afterhours check for the firewall.

Also if you use some kind of WAN failover, check whether your system is now connecting online from a different IP than the one it was originally.. The 3CX SMTP will fail if your FQDN IP does not match the current WAN IP

Amazing I never got notification our comcast went down. All is well.
