Hi,
Everytime the UC560 installed in my network is restarted, the IP phones fails to make external phone calls. All phones and directory are registred and can make calls between the local directories.
When someone tries to make an external call, the call is not connected to one of the voice port and dont go out.
The image installed in the UC560 is:
uc500-advipservicesk9-mz.151-2.T4
Any ideas and ways to fix this issue please
