How To Set Up A 2N Intercom Without Using An IP PBX

Now that you have the IP address of the intercom, you can set up a direct call from it to an extension. (Note that these instructions apply to 2N intercoms running firmware v. 2.24.0 or later.)

  1. In the intercom’s web interface, go to Directory > Users
  2. Click the Add User button
  3. Enter a Username for the intercom
  4. Under Phone Number, enter the IP address of the device you want the intercom to call, using one of the following formats (depending on SIP device):
  5. sip:ip_address
    sip:x@ip_address
    sip:x@ip_address:port
  6. If you want the intercom to initiate the call from a specific button, go to Hardware > Buttons
  7. Assign User to desired button

And you’re good to go!
