3CX intercom solutions

[lewang]

Hello,
I am looking for some choices for outdoor intercom hardware compatible with 3CX. So far I only found the following:

Valcom VIP-172L SIP Intercom
CyberData SIP-enabled VoIP intercom

I would appreciate it if anyone could suggest some other vendors that provide similar intercoms.

Also, I am considering the use of PSTN based intercom and use an ATA device for integrating into 3CX system. This solution would offer more choices for intercom hardware but with added cost. So far this is the only difference I can see between a PSTN based intercom and a PoE based intercom. If anyone could offer some advice in this area I would appreciate it.


Thanks and Regards,
Lei

we use a door intercom from 2N http://www.2n.cz/en/products/communicators/doors/ with 3 CX and it works fine.

We also use an analog ATA (Linksys SPA2102) with a traditional analog door entry panel on another part of our building which also works fine

I use a 2N system as well, with a PSTN connection to a FritzBox, which in turn links it to the 3CX system.

I toyed with a pure IP system, but frankly most of them cost an awful lot still, and for a home I thought it was overkill.

Don't forget to block incoming external calls to the entry phone if you go for one of these; potentially, if someone can dial the extension directly, and enter the release code, they could open your door.

Thanks very much for the comments and suggestions.

In our application, we would like to direct calls made from the intercom in realtime (and vice-versa) so that everytime someone pushes the call button on the intercom we will be able to dynamically direct the call to certain extensions. I think there may be more than one way of implementing this, such as the call control API. If anyone has experience in this area I would appreciate it if you could share some of your thoughts in this area, specifically in what is the simplest way to implement the call control for an intercom and softphone system.

Thanks and Regards,
Lei
