For business / Structure / Many branches
We don't switch every branch at once.
Verify at one, then expand.
We add one line while keeping your existing lines, so even if something goes wrong during verification, the phones you are using are not affected.

OPERATIONS
How it actually runs across many branches
Each branch can use a different setupExisting branches keep their phones, while new branches and those due for new handsets switch to SIP or PC phones. The only difference is whether you buy new handsets.
Adjust concurrent calls without new wiringPhysical lines take only as many calls at once as there are lines. With ZeroCall's SIP setup, concurrent call capacity is a setting.
See totals by branchCheck call activity and totals for each branch on the headquarters screen, by branch rather than by individual agent.
Keep using your PBXYour existing lines and forwarding routes stay in place, and only a SIP line for integration is added. Phones behind the PBX stay where they are.

COSTBranch phone costs depend on the line structureCall forwarding is charged on every forwarding leg; number porting has no such leg. The one-branch measurement from education company A is on the business overview page.See the measured case →
CHECK FIRSTDirect numbers may move as a blockDepending on the carrier, the direct numbers under a main number move together as a block. We check the number ranges you hold before proceeding.See the porting process →
Start by checking your current structureFrom your call logs and phone bills, we show where the money goes and how much on each leg.
