I have the same problem and have to reset it so it will be ok again.
Still don't know what to do to solve it.

Does anyone know how to solve this problem?

I think is the last version, I have the same.
Specifically in my case I have enable the Sip_alg with incoming call working fine.
Another clue in this issue is when i got the nat issues it doesn't affect at all the Sip_alg, the Sip_alg continue working fine
I think I got a problem with mapping port between NAT and SIP .
Any idea???
