I have an SX20 registered in CUCM and only can call to URI or extensions. How can I call to H323 endpoint from SX20. Do I have to configure a SIP route pattern to another device? How?

CUCM is a SIP call control server, so the call would need to go through an Expressway-C/E so it can be interworked to H323.
