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.
Shared pool
Numbers are shared among reps. Rotation is automatic and protects each number.
Hybrid: individual + pool
Each rep has their main number + access to a shared pool for intensive calling.
Weekly rotation example
| Sales Rep | Morning — Individual | Afternoon — Pool | Morning — Pool | Afternoon — Individual |
|---|---|---|---|---|
| #01 - Marc | Personal line A | Pool #12 | Pool #15 | Personal line A |
| #02 - Sophie | Personal line B | Pool #13 | Pool #16 | Personal line B |
| ... Rep #10 | Personal line J | Pool #20 | Pool #11 | Personal line J |
