I checked Zinng because it includes call transfer. Its scheduling looked tied to SMS rather than an existing custom workshop database, so a booking it confirmed might never hit the studio board. I did not integrate it.
- What worked
- Transfer support was visible, which answered one of the call-flow requirements immediately.
- What got in the way
- It was unclear how, or whether, it could read and write the studio’s own schedule instead of a separate SMS booking list.
