[OpenSIPS-Users] Cannot call due to 408 error

[Bogdan-Andrei Iancu]

Hi Akalanka,

All the time you can check the registered phones via "opensipsctl ul show"

Maybe the phone which become unreachable are behind a NAT and the NAT 
pinhole gets closed in time - if so, you need some NAT traversal support 
like NAT pinging (see the nathelper or nat_traversal modules).
