I'm running an Asterisk PBX with a nodejs module for listening to AMI events. One thing I'm trying to capture is sip messages. Watching the asterisk client I'm able to see the message and content but when listening to AMI events I do not see the message coming across. Is there a configuration that needs to be enabled to see sip messages via AMI events (similar to 'sip set debug on' in the asterisk client) or is there another way I would need to listen for SIP messages?
