We're currently searching for the possibility of embedding speed dial feature in Cisco Jabber for Windows.
We tried using Custom Tab but had difficulty making it work.
Thanks so much!
This is a little late, but as of 11.9, you can use the custom tab for speed dials by pre-pending the number in the url field with "sip://". This will initiate a SIP call, opposed to an HTTP request.
Hope that helps!
Where exactly do you configure the custom tab for speeds dials. Do you have any documentation that show you this?
