Since we did an update to the latest firmware (1.1.1.06) we have problems with our telephone system. A little checkup with our telephon provider (nfon - https://www.nfon.com) showed, that they see very often port changes of our telephones. They advised me to set the UDP-NAT timeout accordingly to their documentation (http://www.mynfon.com/en/leaflets/leaflet-plug-play/b-firewall-configurations/) to be more than 65 seconds.
But my problem is that I can't find any setting like this in the config of our RV320.
Please help, as these dropping calls and other problems are really annoying.
