The debug stops here, cause for over than 20 seconds it remained with the
last line displayed and no activities.


on the CLI it remains the voice " CLI> called g1/803121"

Usually, when the number is really ringing and answered, after the "Called"
line, appears the "ZapX-X is ringing" line, that doesn't appear here.

Thanks again,

Stefano Finetti
