[asterisk-ss7] chan_zap.c:9844 zt_ss7_error: !! Unable to handle message of type 0xd on CIC 2002

[Veneraldo Apelo]

Hi List,

I encountered the following error when I made a test call from a SIP 
extension: chan_zap.c:9844 zt_ss7_error: !! Unable to handle message of 
type 0xd
But the call can get through, although there was no caller-id. Hereunder 
is the trace and my configuration:
