Im trying the sample code provided for the Jabber web SDK (the softphone that you can use from a web browser) but it cannot connect with the devnet sandbox CUCM (a week ago I tried and it was working). Let me explain the details:
I reserved the Collab Endpoint sandbox lab and created a Jabber windows client, so I received an email with the user name and password.
When I run the sample code (the web browser softphone) I click on start discovery and when it ask for an email I enter my user firstname.lastname@example.org
Then it asks for username and password so I enter again my user email@example.com and the password.
Then I can see my device CSFxxxxxx9F32, so I choose it and click on connect.
Then an error message is displayed saying "Unable to sign in or connect: Cannot connect to CUCM server DeviceRegTimedOut"
I tried disabling the firewall and antivirus but it didn't make any difference.
It works if I connect to the VPN with anyconnect but unfortunatly I need to make it work with the expressway.
Is the expressway working in the Collab Endpoint lab?
