Today I am going to share with you, my dear readers, some experience of working with Cisco cloud telephony - Cisco Webex Calling. One of my customers received his own tenant in Webex Calling and started using it. So, they received access to Webex Control Hub, they configured some users with extensions for testing, etc. The users could normally login to Webex Application with their accounts and see their extensions.
However, they were surprised to discover that when they try to make an internal call from Webex App to Webex App and dial extensions of each other, the call just fails. They can hear the message from Webex Annunciator like ""We're sorry, but your call can not be competed at this time..." This not what our customer expected from the newest cloud telephony system, right? ))) Let me tell you, how it was solved.
