2N IP Intercom

|Secure RTP (SRTP)|
This guide shows how to setup direct calling between Yealink T58A/V and our IP Intercoms.
If you configure everything according to this guide you’ll be able to automatically see video preview from up to 99 intercoms when a call is received on the phone as well as activate switches on intercoms. Additionally you’ll be able to call every 2N IP Intercom in the same network.
IP addresses used
- 2N IP Intercom 192.168.50.129
- Yealink T58A 192.168.50.188
Firmware versions tested
- 2N IP Intercom 220.127.116.11.4
- Yealink T58A 18.104.22.168
Both devices were in factory defaults.
After you log in to the intercom, go to Directory.
Add a new user.
Name the user and enter a new phone number in this format: sip:yealink’s IP/1. In my case it’s sip:192.168.50.188/1. Entering the /1 is very important to identify the intercom properly.
Delete 111 from the Phone Number (ID) field and leave it empty, then change Domain to the intercom’s IP address – in my case 192.168.50.129. This will allow you to call the intercom directly from the phone’s call log.
If you’d like the intercom to pick up calls (from the phone) automatically, change Call receiving mode (SIP1) to Automatic.
The Yealink offers an “Open Door” button function. To use this you should enter the intercom’s Switch Code into the phone’s configuration to open doors without having to enter this switch code manually. Firstly; this code has to be defined in the intercom’s configuration: Hardware>Switches>Switch#>Switch Codes or in Directory>Users>User#>User Codes.
Configuration of the phone is very straightforward. Pick one of the DoorPhones from the Door Phone List and set it as follows:
Device Type: 2N
Display Name: according to your preference
Phone Number: intercom’s IP
Unlock PIN: 00* – Don’t forget the asterisk. This PIN has to be a valid code set in your intercom in step 6 of the intercom setup
Full Screen: Disabled
Send Audio: Enabled
Send Video: Enabled
Video Preview: Enabled
Auto Preview: Enabled
This is all that needs to be done in order to get video preview, activate switches and be able to call both ways without a SIP proxy.

After you log in to the intercom, go to Services and then HTTP API. Locate the Camera API row and change Connection type to Unsecure (TCP) and Authentication to None.
If you’re getting poor framerate or would like to save some bandwidth, you can decrease JPEG quality in Streaming>JPEG down to 50.
Log in to the phone’s web interface and go to DSSKey tab. Choose one of the Line Keys, click on its Type dropdown menu and select Video Monitoring. The most important field here is Value, this is where you put the address of the intercom’s HTTP API camera stream in the following format:
The remaining fields are Label and Extension. Label is the name which will identify the intercom’s camera on the display of the phone. Extension is not important in this scenario, but you can enter the intercom’s IP.
The following picture shows that I have assigned two intercom cameras to the phone’s DSS Keys using their respective IP addresses.
How it works
DSS Keys are accessible on the right side of the phone’s home screen.
Once you tap on them, they immediately show your intercom’s camera feed.
