We are replacing a nortel system. There is a buzzer at the front door that dials an extension. The system was digital and used 4 wires. What can I put here? My thoughts were to use a gateway at the other end so we can utilize the same cable.
Digital takes two wires, maybe the other pair was for power. You can put in asterisk/FreePBX only what you have, please be more explicit as to “what you have” . . .
… and what you’ll be comfortable with as a replacement.
I’d start with the “Viking” catalog and figure out what you want from there.
yes. The other two were for power. It was an old nortel system. It’s a buzzer / door unlock system. I was looking at the Viking E30-EWP but it is like over $500 in parts.
