SIP via TCP/TLS (encrypted signaling)
Outbound-Proxy (Send data via session border controller)
Door Bell Setup
On the PASCOM admin web interface, go to Devices > Device List and click Add. In the next window select the template for generic Doorbell.

Below you will find an overview of door bells that have been tested by PASCOM during the implementation. In general, you can use any SIP-enabled door bell. The following URL addresses must be set up on the door bell itself and also on the PASCOM telephone system. For the configuration of the door bell, also have the manufacturer's documentation available as a useful aid.

Door Intercom usage
The door intercom establishes a normal call when the bell is pressed, which can be received via SIP/SRTP from anywhere. The PASCOM App does not have to be in the same network.
Door opener usage
To open a door, the PASCOM App sends a DTMF code during the active call. The PASCOM App does not have to be in the same network and the door opener can be operated from anywhere.
Useful Information
Why do Iphone devices have a black image when streaming video?
If the door bell delivers the image/video data via HTTPS with a self-signed certificate, no image may be displayed on iOS devices. This is an iOS security policy. To get a picture, either a trusted certificate must be installed or the door bell must be switched to HTTP.
