DoorBird's video intercoms are built on top of standard IP video and audio technology, which means they can integrate with more than just the DoorBird app. For customers who want to tie their door station into a broader phone or intercom system, DoorBird supports SIP-based calling and a related concept commonly referred to as DoorBird Connect. This article gives you a general, non-technical introduction to what these features are for — full configuration is a job best handled by an experienced installer, and we'll explain why below.
What is SIP, in plain terms?
SIP (Session Initiation Protocol) is the industry-standard technology that powers most modern voice-over-IP calling — the same underlying concept behind office phone systems and many video intercom platforms. Because a DoorBird door station is fundamentally an IP-connected audio and video device, it can place and receive SIP calls, not just calls routed through the DoorBird app itself.
This matters for properties that already have (or want to build) a phone system, PBX, or intercom network that isn't just "a DoorBird app on a phone." Examples include:
- Multi-unit buildings where visitor calls need to ring an existing internal phone system rather than individual residents' personal phones
- Businesses that want the DoorBird to ring into their existing office phone infrastructure
- Properties using third-party SIP-compatible indoor stations, intercom panels, or IP phones instead of (or alongside) the DoorBird app
SIP Favorites
Within a SIP-based setup, a "favorite" is essentially a saved SIP number or address that a call button (or a set of call buttons) is configured to ring, similar to how the DoorBird app normally rings a saved user's phone. Instead of the button ringing a DoorBird app account, it rings a SIP endpoint directly — which could be a desk phone, a SIP-compatible indoor monitor, or another intercom station.
Setting up SIP favorites generally involves registering the DoorBird device with a SIP account or server, then mapping specific call buttons to specific SIP addresses so the right button rings the right destination.
What is DoorBird Connect?
DoorBird Connect refers, broadly, to DoorBird's approach for linking door stations into this kind of extended calling and intercom ecosystem — essentially the layer that makes SIP-based calling, favorites, and cross-device intercom communication work together as a coherent system rather than a collection of one-off SIP settings. It's the concept that lets a DoorBird device act as one node in a larger IP intercom or telephony deployment, rather than only functioning as a standalone doorbell tied to the DoorBird app.
Why we recommend involving a technical installer
SIP configuration touches several layers that need to work together correctly: network settings, SIP account credentials, codec compatibility, firewall and NAT traversal, and the specific requirements of whatever phone system or SIP server you're connecting to. Getting any one of these wrong typically means calls that don't connect, one-way audio, or a device that appears "registered" but never actually rings anything.
Because of that complexity, this is genuinely one of the areas where we recommend working with an experienced telecom or low-voltage installer who's comfortable with SIP/VoIP systems, rather than attempting a full deployment purely from general documentation. Think of this article as the map that tells you the feature exists and roughly what it's for — the turn-by-turn configuration for your specific SIP provider or phone system is best handled by someone who works with that system regularly.
