Intercoms and SIP Integration: The Future of Access Control
Today, intercoms are much more than a doorbell with a camera. For installers, the question is no longer “which intercom should I choose?” but “how do I integrate this intercom into my customer's wider communication system?” And that's where SIP integration comes into play.
What is SIP and why is it important for intercoms?
SIP (Session Initiation Protocol) is a global protocol used for VoIP telephony. In concrete terms, this means that an intercom with SIP support can communicate directly with:
VoIP phones
PBX systems
Softphones and apps on smartphone or laptop
The big advantage No closed systems or expensive licenses, but open integration with existing infrastructure.
The benefits of SIP intercoms for installers
Project flexibility A SIP intercom can be linked directly to an existing VoIP exchange or cloud PBX. This makes it easier to implement intercoms in offices, businesses, and apartment buildings without additional complex cabling.
Cost savings for the customer Because SIP is an open standard, fewer extra modules or licenses are required. This is a strong selling point for customers who are often budget-conscious.
Remote management and updates Many SIP intercoms are easy to configure and update via the network. Less time on-site means more efficiency for you as an installer.
Scalability From single-family homes to large office buildings: SIP makes it easy to expand systems with multiple indoor stations, telephones, or even complete call routing.
Concrete applications of SIP intercoms
Office buildings
Forward incoming calls from the intercom to the front desk or security VoIP phones.
Apartment buildings
Each resident can connect their own device (smartphone, softphone, VoIP device) to the intercom.
Work from home scenarios
Entry calls from the intercom can be forwarded to the user's smartphone or laptop, no matter where they are.
