IWF: H.323 endpoint with no registration to SIP - Lack of Destination number in SIP message

Hi friends,

I'm trying to configure IWF for H323 to SIP video (h264) calls in an access scenario with no endpoint registration.

Endpoint --(H323)--> SBC --(SIP)--> MCU

When I made a H.323 call with called number 999 to SBC, the SBC converted to SIP message, while in the SIP message there is NO 999 presented in either TO header or request-URI.

I checked the H.323 side, the number 999 did show in the H.323 message as “url-ID: h323:999”.

Any suggestions? Many thanks!

H.323 Message:
