ALTERNATIVE MODELS in our DS-Range for Analog Extension or FXS Port connection

Model DS4 – Is designed to go 'Off Hook' when triggered by ANY NATCOMM Door Phone Intercom, so that the PBX can 'Hot Dial' the Intercom call to any Telephone Extension or Extension Group. DS4 will then terminate the call on detection of hang up tones, which occur as soon as the user hangs up.

Model DS5 - Has all the features of Model DS4, plus it has an Internal Relay to allow the User to Open a Door or Gate by pressing ** on their keypad. The Door or Gate will open for a user programmed amount of time.




For Residential Use OR for use with a 'Closed Cloud PBX Service' where 3rd Party Equipment is not supported


The Smart Cloud Internet Service' will work with ANY Cloud PBX because it does not connect to it in any way. It connects to a totally separate ‘Smart Cloud’ INTERCOM service, which is provided for NATCOMM users by a 3rd party service.

In this situation, the DS-SIP Controller is completely configured here at the factory and sent to you for ‘Plug N Play’  installation. You just need to connect it anywhere on your Internet Network and it will connect to the ‘Smart Cloud’ Server by DHCP (or Static IP if you prefer).

DS-SIP will be configured by us to Dial direct into your Closed Cloud PBX service as an incoming call. Ideally a DID number should be setup by you, so that DS-SIP can call specified PBX Extensions.


The cost of this complete service is just $2 per month, plus $0.10 per Intercom Call.
This will be billed by the 3rd party provider of the ‘Smart Cloud’ INTERCOM service.
