# Register SIP Devices for Voice Endpoints

> Register softphones and desk phones as SIP endpoints so Ringingo can route inbound and outbound calls to your users and managers.

SIP Devices are the registered voice endpoints linked to Ringingo user and manager accounts. Each device is a SIP-registered endpoint, typically a WebRTC softphone or a physical desk phone, that the platform uses to route inbound and outbound calls to the account holder.

<Warning>
  SIP device credentials (Username and Password) are sensitive. Never share them over plain-text channels. A compromised SIP credential can be used to place unauthorised calls on your account and incur unexpected charges.
</Warning>

<Tip>
  When creating a new user or manager, create and assign the SIP device before the account goes live. Without a registered SIP device, the account cannot make or receive calls.
