Nww that I have everything configured to send messages between Mobicents
and Asterisk via SS7, I have the following problem, Mobicents sends SCCP
messages to Asterisk and Asterisk outputs this error:
[1] Len = 111 [ 81 85 3f 03 03 40 00 30 09 01 03 0e 19 0b 12 08 00 12 04 29

I have been looking online for a way to get Asterisk to interpret the SCCP
messages but can only find references to Cisco phones. Can anyone suggest a
way I can read SCCP messages in Asterisk?
