How to configure 2N® IP intercom?
As a very first step go to the section 
"Directory – Phone Book", enable the desired position in the Phonebook and set the "Phone Number" to be dialled once you press an appropriate button of the intercom. If you want to call to the 2N® IP Mobile application, the number has to be filled in a format: "device:name". In our example the device name “ipad” is being used, please see the picture below.
In the next step you can set the intercom to automatically pick up the incoming calls in order to easily reach it at any time. Go to the section 
"Services – Phone – Calls" and enable Automatic Pickup for incoming calls for both SIP1 and SIP2, see the picture below.
As a next step go to the section "Services - Phone - SIP 1" and fill in the "Domain" field. For direct calls from the 2N® IP Intercom to 2N® IP Mobile application it is recommended to fill in the IP address of intercom as shown in the picture below (IP address of the intercom in this example is 192.168.50.10).
How to set 2N® IP Mobile?
To be able to receive calls on the 2N® IP Mobile you need to set the device name first. The device name is used by the intercom for the call routing instead of the IP address. Please go to Section "Settings - Settings" and edit field "Device name". We choosed name "ipad".

Door Lock details
The door lock can be triggered by the lock button at any time - during the preview or during an active call as well. If you would like to trigger some other lock than the default Lock 1, simply hold your finger on the lock icon for a while and all 4 locks will appear.
There is also no need to set any lock code, the communication with the 2N® IP Intercom works on a proprietary HTTP command basis.
