state timeout (VOIP)
«

Hello everybody,
i have a opnsense setup with ~70 clients and a 100/100 fiber connection.
We have SIP softphones running on our Laptops and since we are using opnsense our calls just stop sometimes after 20-40 minutes. I already set the firewall optimization to conservative but it did not really help.
I am looking for a way to configure the udp timeouts. Or does anybody have any further ideas?

Is there really no way to do that? That would mean that Opnsense is pretty useless for VOIP....

UDP does not have timeouts of 20-40 minutes.
First and foremost you need to find out if the firewall drops your packets. In the firewall logs you can find such drops under the rule "Default deny rule". It means that state tracking does not allow your states to persist.
If that is the case you can disable state tracking via advanced rules.
If that is not the case you need to find out why your calls drop or try TCP to troubleshoot.
Cheers,
Franco
