Tested With

This has been tested with the following third party solutions. Please let us know if we can add more systems to this list.

• 2N IP Verso (& Control4 DS2) - See the 2N user guide here
• Doorbird - See the Doorbird user guide here
• Akuvox
• Linphone

Configuration:

In many intercoms, it is possible for a button push to initiate multiple P2P SIP calls simultaneously, thereby allowing the intercom to ring on multiple Rithum Switch Pros.

The intercom unit will need to be configured to make a direct P2P SIP call to the switch, the address/phone number to enter being:

sip:<Switch IP address>:5060

Some systems may require a caller ID to be added, in which case you can use anything generic such as 123 in the following example:

sip:123@<Switch IP address>:5060

Note: It is recommended to bind the IP address of each of your Rithum Switch Pros within your router settings so that they don't change.

Example screenshots below are for configuration of a 2N IP Verso.

If possible, set a 'Display Name' for the SIP account in the intercom unit. This name will then be displayed as the caller on the Rithum Switch intercom screen. For example:

Configure 'Intercom' settings on Rithum Switch Pro:

• Initiate Demo Call: Press this to initiate a demo call which will cause the intercom screen to be shown
• Unlock DTMF Code: Enter DTMF digits to be sent when the intercom screen unlock button is pressed. The default code for 2N is 00*
• DTMF mode: Select RTP or SIP INFO depending on what options are available in the intercom unit
• Hang up after unlock: Enable this option to automatically end the intercom call when the unlock button is pressed
