Generate SIP call with switch

We have a client for whom we’ve installed phones. They have doors with a buzzer button on their old system. Because of construction/wiring issues, it’s best if we reuse the existing door buzzers, which are simply two-wire push buttons. Is there such a device that will generate a SIP call when a contact/swtich is closed? There are many models of door buzzers that will do this, but all we’ve seen would require network cabling to the buzzer, which isn’t feasible.

Thanks!

What do you expect to happen when de buzzer is pushed…?

Setting up a voip call to the buzzer… which has no mic/speaker…?

Or do these buzzers have a mic and speaker?

Check out the Algo 8180, it has a relay input you can use to trigger a call.

Looking for the same…
