If you use audio optimization settings or receive calls from other IP addresses than the Voxalot server where you have your phone registered, you need to use stun server or redirect IP ports on the router (maybe you should use both). When you see 'mapped sip ports 41898 and PSTN to 31678', that is done by your router NAT. What happens is that your router hidden all your IP devices in your LAN on one WAN IP connection. For example: in your LAN you have several devices (computers, IP phones, etc.) with IP addresses such as '192.168.1.251'. On the other hand, your WAN address is, for example, '82.155.26.153'. What NAT does is assigning one IP Port to each device connected on your LAN but with the same WAN IP address. In the above example, you phone devices would be, on the WAN side, '82.155.26.153:41898' and '82.155.26.153:31678', but on the LAN side, they would be, for example, '192.168.1.251:3060' and '192.168.1.253:5060'. So, what you see is the normal behaviour of your router which connects all your internet devices on the same WAN IP connection.
