The MOBOTIX IOT camera can establish an audio or audio/video sip connection with any SIP client.
This article describes the connection between the SIP client Linphone and a MOBOTIX Q25 that establishes the connection between the two devices based on a direct IP call (direct SIP call) in a local network without using SIP servers, SIP accounts or SIP registrars.
SIP Client used:
In the case described, the macOS variant was used.
A MOBOTIX Q25 was used as the SIB remote station.
The basic requirement for this setup is:
Camera has activated Sip Client
Camera has Micro and Loudspeaker activated
Camera and PC are in the same subnet
PC has Linphone installed
IPv6 is deactivated in the Linphone settings.
In my case the camera had the IP 192.168.1.149 and the PC 192.168.1.18 with the subnet mask 255.255.255.0.
- Install Linphone
Please ignore the suggested paths (buttons) displayed below!
- Deactivate IPv6 in the Linphone settings
Restart Linphone if necessary

Enter the address of the MOBOTIX Q25 in the middle input field at the top of the dialog in the following form:
Then press the camera icon to start the call.
Then the connection with the camera is established with image and sound.
