Door phone dialer compatibility with 3CX

[teldata1]

We're proposing a 3CX system to a client with a door-phone dialer that dials a 10 digit phone number, the 10 digit phone number is routed to the phone system and the user presses a digit on the keypad to create a DTMF tone to unlock the door strike at the front door. Will this dialer be compatible with 3CX? We're proposing Yealink T4x series phones as well.

Yes. As far as 3cx is concerned it's just a regular phone call coming in. If that doesn't work, that same system would have dtmf issues in conference bridges and ivrs as well ..

Any incompatibility issues would arise because of the ATA chosen, or it's configuration. There should not be problems, but some "tweaking" may be required. There are a number of VoIP Door control units available. If you are staring from scratch and not adapting to an in use system, you might want to investigate.
