[asterisk-users] cause 66 - Channel not implemented

[Vieri]

Hi,

What can I make of the following log messages? Extension 7114 tries to reach 6035 but gets an "unknown channel type". What does it mean? (supposedly, 6035 was not busy...)

Apr 12 13:01:01 VERBOSE[30989] logger.c:     -- Executing Dial("SIP/7114-b4fe1ef0", "/6035|300|") in new stack
Apr 12 13:01:01 WARNING[30989] channel.c: No channel type registered for ''
Apr 12 13:01:01 NOTICE[30989] app_dial.c: Unable to create channel of type '' (cause 66 - Channel not implemented)
Apr 12 13:01:01 VERBOSE[30989] logger.c:   == Everyone is busy/congested at this time (1:0/0/1)

Thanks

Vieri
