SX10 to CMR cloud

[Jean Paul Enerst]

Hi Gents,

Hope you fine gentlemen can help me out here... I am trying to get an SX10 which is registred with CUCM to call to webEx CMR using the IP address as one of our devices does not support SIP. But i keep getting: SIP/2.0 400 Bad Request - 'Malformed/Missing URL'

Call Flow is: SX10 >>>> cucm >>> Expressway

But calls never make it to expressway, drop by CUCM. Here is what i get from the SDL file

SIP/2.0 400 Bad Request - 'Malformed/Missing URL'
Via: SIP/2.0/TCP 192.168.87.87:39019;branch=z9hG4bK00bd3d8686fbcad28e5039c6333d467f;rport

I'm confused on your description of the problem:

"I am trying to get an SX10 which is registred with CUCM to call to webEx CMR using the IP address as one of our devices does not support SIP. "

If you have an SX10 registered to CUCM, it's registered as a SIP client, and if you have Expressway setup for internet/B2B calling, that should be a URI call to Webex, typically the nine digit meeting number @yourcompany.webex.com

For IP address dialing to work from CUCM registered endpoints, you usually will use some kind of trigger - at my company we dial the address with a suffix of "@ip" - so for example 1.2.3.4@ip, then in CUCM there's a route pattern to send it to Expressway and it works.

Thanks, JPMack... I appreciate your input.

Here is the deal, internal i have no issue to dial to WebEx.  And yes, we dial the meeting ID follow by the IP address as our UC platfor is fully SIP supported. However, our Parent Computer which is in Asia, their Vid Conference devices do not support SIP, they support H323. I do CUCM can dial H323, I have added a SIP route pattern with Webex external IP address which is also add in the meeting invite,still CUCM rejects the dial with : SIP/2.0 400 Bad Request - 'Malformed/Missing URL'
