There are two different SIP channel drivers. If using chan_sip then "sip
set debug on" will show you the SIP traffic, if using chan_pjsip then
"pjsip set logger on" will. After confirming it you then look at the
configuration. You would need to ensure that you are matching the incoming
traffic against either a peer for chan_sip (host= in a peer), or an
endpoint in chan_pjsip (identify section). You'd also need to confirm that
you haven't configured it to challenge those calls for authentication
(insecure=very in chan_sip, and not having auth or inbound_auth set on
endpoint in chan_pjsip).
