OK, good to know.

Do you access $ci and use other dialog module functions when processing
the xmlrpc command (inside the xmlrpc event route callback function)?

But still RTPEngine keeps sending that event message for three more times. Kamailio has to respond to it with call-id not found. Which is overhead. Not recommended for production environment.
