UDP Session timeout parameter?

I just installed a hosted PBX VoIP solution at one office. There is a software receptionist console that required a UDP port to be opened to the hoster's network. All good so far. But they said on most firewalls you have to expand the UDP session timeout to avoid having to constantly reconnect the software console. I don't see anywhere on the ASG120 V7.5 to set a parameter like that.

# cat /proc/sys/net/ipv4/netfilter/ip_conntrack_udp_timeout
30
# cat /proc/sys/net/ipv4/netfilter/ip_conntrack_udp_timeout_stream
180

You can change those settings with sysctl, but Astaro may reset them again.
Keep in mind that increasing these timeouts increases the # of connections Astaro has to keep track of, increasing RAM usage.

What would the default time out be for Astaro?

For UDP, it looks like it's 30 seconds, and 180 seconds for UDP streams.
