In reply to Amit.

@Amit, thanks for reading. Webex has 24x7 support globally via email, chat, or phone in our Collaboration Help Portal available to customers anywhere in the world. I’m not sure what issues you are having but users can click for help from within the product, your site, or an email; then your request is automatically queued and routed. You may want to contact support outside of the meeting to troubleshoot the issues.
