Sending MF Tones to analogue station port

[NinjaUK51]

Hi there,

We have a requirement to be able to send MF tones to an anologue station port from IP Phones.
The analogue station port has a door entry system connected to it which will be programmed to go off hook and dial a hunt group number. When answered by an IP phone we will need to dial a string of digits (sent as MF tones) to the port in order to activate the door opening mechanism.
Is there a FAC or a button I can program on the IP phones in order to do this?

Thanks.

Program one of the IP stations buttons for auto intercom.

Build the target intercom station an analog port. Connect a Bodgen TAMB, which provides contact closure when ringing voltage is applied.

Set the COR for the analog station to only allow intercom calls.
