Has anyone tried to create a SIP trunk between Asterisk and a CUCM? If so has
anyone enabled tls on the trunk? Would the tlscafile field in the Asterisk
sip.conf be used to refer to the pem file provided by the CUCM? Is the purpose
of tlscafile to refer to the other call manager's pem file? Or would the
tlscafile field need to refer to the ca.crt file created for Asterisk using the
asterisk ssl tls scripts? Attempting to use self-signed certifications for both
Asterisk and CUCM. Does anyone know if the asterisk.pem file (created by using
the asterisk ssl tls scripts and provided to the CUCM) needs to have the Issuer
CN and Subject CN identical to avoid an Unknown CA error on the client key
exchange?
