SX80 h323 call issue

[ziad nasr]

Hi,

I have a SX80 with software version CE 8.2.2 registered to my call manager v11.5 via sip.

i can call all internal extensions and can call external pstn numbers.

the issue is most of the VC out there uses H.323 so when i attempt to call and H.323 conference via ip the call is rejected , after checking the call log, it is using sip and not H.323 although h.323 is enabled and set to direct ( no gatekeeper),

in order to bypass this issue i informed my client to add the called address as a contact and manually select the control protocol for that contact.

But this is not a solution for my  client since it can only be done from the web interface and the conference users are high level management and don't have time for doing so.

Please i need solution as this is not acceptable for me. and yes i tried to use x*x*x*x  or x.x.x.x@domain with no use all using sip not h.323 

Best Regards

From the touch panel you can add h323: in from of the IP address, this will force the endpoint to dial using H323.

Example= h323:1.1.1.1

Other than that, you will need to deploy VCS/Expressway servers in order to do the interworking from SIP to H323, please check http://www.cisco.com/c/en/us/support/docs/unified-communications/telepresence-video-communication-server-vcs/118884-config-vcs-00.html

CUCM doens't support H323 or IP dialing, as it's a SIP only call control server.  To make H323 and IP calls, you'll need either a VCS or Expressway to interwork the SIP call to H323, and transform the called SIP address to an IP address.  See the document that Enrique linked to in his reply.

Thank you the trick did it it we get our vcs express way up.

but you know most of the VC out there uses H323 and Cisco must find a solution for this.
