[...] Would you say it's possible to install several intercom phones on the same line, both ringing at the same time (but only one of them being able to answer) ? If positive, is it possible to connect one intercom line to asterisk and let an asterisk user talk or watch visitor before opening the door (through a DTMF sequence, for instance) ?
Sure you can. Any intercom can be connected using a IP gw connected to asterisk. You then install an IP camera and it's done :-) Opening the door is done by sending the code using asterisk sendDTMF command.
That's what we do when using existing intercom. For new installations we use Mobotix products (IP doorphone in SIP).
