Nattapong,
his community does not provide technical support and is not staffed with technical support experts. I recommend you post this and future technical support questions to the Cisco Support Community (https://supportforums.cisco.com/index.jspa)--specifically in the Telepresence space under Collaboration Voice and Video--where our Cisco technical support experts provide assistance. Another option is to open a ticket with the Cisco Technical Assistance Center (www.cisco.com/go/support) to get expert assistance.
We do encourage you to participate in the Cisco Collaboration Community and to also join our Cisco Collaboration User Group program! In the community, we encourage your discussion/sharing around collaboration topics and Cisco Collaboration Solutions, including business and IT requirements, industry trends, process, culture/organization issues, how collaboration can be used to transform businesses, vendor selection, adoption, training, architecture, licensing, and product features/functionality. If you are a customer or partner, you can also join the user group program to be eligible for member-only events and influence product direction.
We hope to hear from you again.
Kelli Glass
Moderator for the Cisco Collaboration Community
