What do you like best?
I love the simple layout. Jabber is more responsive than Skype for Business. Jabber offers comparable features to Skype for Business, such as voice calls, video messaging, screen sharing with remote control. Has the ability to change fonts/colors/styles. Conversation history can be saved. Ability to add avatar. Ability for Windows, Mobile, and MAC applications. It does handle Voice Mail if you have supported features, and does integrate with outlook for upcoming meetings, and will change your availability status if you're in a meeting. Ability to call into Cisco Webex meetings
What do you dislike?
The inability to search prior conversation history. You can only scroll through the past conversations, unlike Skype for Business that if enabled, sends conversations to a folder in your inbox that you can use to search through with Outlook.
Also having multiple Webcams (integrated vs external) and mic types confuses Jabber at times and even though defaults are set many times the application forgets them. Screen share quality at times seems less quality than running Skype For Business.
Recommendations to others considering the product
Skype for Business is hard to beat at $5/month if your company utilizes Office 365 Subscriptions.
What business problems are you solving with the product? What benefits have you realized?
Ability to quickly communicate with colleagues. Users can have video conversations with any employee around the world as long as they have a somewhat stable internet connection. Ability to get simple questions and requests answered and taken care of without composing an email. Screen sharing allows IT to see error messages, or allows end users to share presentations with others, again without having to attach the powerpoint, send it via email, and then clutter up your mailbox.
