Keep the numbers and the workflows. Replace the box, the chan_sip stack or the suite you cannot extend.
This is the outcome for teams who already have a phone system and need it off the appliance, off chan_sip, or off a suite they cannot change. Services supply the engines. This page is the job: move production without losing the DID.
IT and operations who cannot buy another hardware IPPBX and cannot freeze the current vendor for five years.
A written move plan, a parallel SIP path and a cut that can roll back.
Replace hardware PBX, migrate to hosted PBX, office phone system modernization.
Inbound reputation does not reset because someone ‘got a new number’.
Reception, hunt, voicemail — then extras.
Software PBX you can SSH, not another locked appliance.
WebRTC, SaaS tenancy or AI voice when the path is stable.
Send the current architecture, call volume, carriers and the workflow you need to automate or productize. Discovery can start from a broken PBX or a blank product brief.
