The VoIP phone works fine most of the time, but when it has some problems I find these informations in the system log:

1) "can not find any account forthe incoming call"

2) "prefix 'x', you enabled this rule for some endptbut didn't indicate the destination". This string is at "Warning Level".

What do these errors refer to? And how do I fix them?

I'm using TIM (Italy) Fiber FTTC with Public Dynamic IP with PPPoE and VLAN ID needed. I need your help, because I searched on the internet and I didn't find much, thanks.
