Red marks in dashboard

[gbusoni]

So I have a few red marks in my dashboard:
1)firewall. if I run the test, i get
In SIP Server
detecting SIP ALG....detected sent .... received ...
and then many mapping does not match errors, for 5060 5090 and all media ports.

Note that ports 5060 and 5090 are actually set to be mapped...some of the media prots too, not all, as I only need 4....

How to fix this? The server is working at the moment anyway, just annoyed to get this red mark

2)sip trunks
I have 3 sip trunks, all made with custom provider, as they were made long time ago. Now, 2 out of 3 are from actually certified providers. Do I need to do anything to ensure that they are actually using the best settings? Is there any way to update them to match the provider trunk templates? Or I do ned to delete and recreate them?
The third provider is not certified though, so I think I won't get rid of this red mark anyway...

3)System extentions
Voicemail (99) is red...is this because I am using Exchnage for voicemail? If yes, how to get rid of this? Or this means that thare is some misconfiguration with the exchange unified messaging?

On the SIP trunks which are now certified providers - you will need to delete / recreate them using 3CX templates

On the firewall test, have you disabled SIP-ALG on the firewall ? Configured the firewall with the correct ports - https://www.3cx.com/docs/manual/firewall-router-configuration/

What version of 3CX are you running as 16.0 had issues with the firewall test, which has been fixed with 16.0 Update 1

The 3cx server is behind windows NAT. Does Routing and remote services have sip-alg? How to disable it?

Version is up-to-date

ok, it seems like windows RRAS statically maps incoming connections to ports external 5060, 5090 and media ports to internal 5060, 5090 and media ports. However, outgoing connections starting from local 5060, 5090 and media prots are not mapped to external 5060, 5090 and media ports. I don't know how to configure this in RRAS
