How to distribute numbers

1 fixed number per rep

Each rep has their own number. Simple but risky: if the number burns, the rep is blocked.

For small teams only

Shared pool

Numbers are shared among reps. Rotation is automatic and protects each number.

The most common choice
RECOMMENDED

Hybrid: individual + pool

Each rep has their main number + access to a shared pool for intensive calling.

Best risk/efficiency balance
