Ylopo leads already in Follow Up Boss? Ylopo pushes each lead there in real time, so you can route them from Follow Up Boss instead.
Ylopo's AI Voice works through Follow Up Boss, so the same lead could get a call from both AIs, and one is plenty. Point Callingly at the leads Ylopo's AI isn't calling, or use Ylopo's own rules (by CRM stage, assigned agent or tag) to keep its AI off the leads Callingly calls.
