We get the following phenomenon:
A terminal makes an ISDN connection to the AS5350 with an ISDN line that does'nt send its CLID (q931).
The terminal gets connected but the AS5350 cann't route ip packets back to the terminal.
'Debug ip packets' gives as information 'encapsulation failed'
When we redo the same exercise but with a ISDN that presents its CLID we have no problem.
Has somebody an idea what's the reason for this behaviour.
