This has been disaster

When I got collaborate it disconnected my voicemail. This is extremely slow, hard to use, and you can’t delete an email without the whole thing playing at least half the time. I’ve tried to get ATT to turn it off and go back to voicemail without success.

I’ve been an ATT customer for many years, have several lines , and am considering dropping them as a carrier solely because of Collaborate.

Works fine for me

Gotta say, these reviews gave me pause, especially since this is a work thing for me. Gotta say I haven’t had any issues with mine. Calls dropped until I allowed WiFi calling - it was cell coverage. I haven’t had any issues with voice mail, and I stay logged in. I’m really happy with the app, and clients don’t get my personal number any more.

Worst app in existence

This app is awful, constantly lags and voicemail never works. Tells everyone who calls that voicemail box is full when it’s definitely not. Have to uninstall then reinstall every few hours or else voicemail doesn’t work at all. There’s got to be a better app for business voicemail and phone directory???
