• Administration web page is little bit hard to understand at the beginning specially if you are not familiar with naming convention and GU Interfaces.

• Voicemail handling for queues and groups can't have their own shared voicemail box.
• They recently starting limiting how many greetings you can have per user, so you have to do some annoying workarounds by setting up additional users to accomplish it when you have a number of ACD.
• Does not yet support texting.
• I wish they had built in text to speech to quickly build new greetings or phone tree options when needed.
• You can't just assign a phone number to a call queue or group. You have to use a specific user. Fortunately, the cost is reasonable per user so its not a big problem, but annoying none-the-less.
• The Salesforce integration could be better, I hope they improve it. For example, voicemails and call logs don't show up in the native lightning case feed, but as tasks.
• When callers call, I wish it would pop up how they called and what tree they went through. So we could see what number they called into and perhaps what menu options they used.
• I'd love to be able to ask them questions to gather info for reps answering phones when appropriate.
