Warm transfer is honestly the thing I use constantly. Before, transferring a call meant the next person had zero clue what was going on, customer had to repeat their whole story again which is just annoying for everyone. Now I can actually talk to the person I'm transferring to first, give them the quick rundown, before the customer even joins. Feels way less clunky. Also the mobile app is decent, I checked queue status from my phone once when I stepped out for lunch, worked fine. Review collected by and hosted on G2.com.
Honestly the multi-language IVR menu setup was a headache. Wanted Spanish and English options and it took forever to get the routing logic right so people didn't end up in the wrong queue based on which language they picked. Review collected by and hosted on G2.com.
