Ignoring incoming calls on an analog telephone interface in Tesira
A call feature which we've gotten used to, thanks to cell phones, is the ability to ignore an incoming call. This feature has been duplicated in VoIP telephone systems where pressing the "end" key will effectively end the incoming call before it's answered and stop the phone from ringing. Analog lines do not have that feature but with a small modification to your Tesira configuration we can duplicate that functionality.
Programming
- To add this feature, we will need a Mute block, a NOT Gate and a Preset Button block. Wire the NOT Gate block and the Preset Button block to the TI Control/Status block, and the Mute block to the TI Receive block as shown below:
- Create a preset to un-mute the Mute block that we just added
- Assign this new preset to the Preset Button block
Ignoring a call
To ignore an incoming call, simply mute the Mute block. The Mute block can be controlled via Tesira software, a Canvas control surface, or a third party controller like Crestron or AMX. When a call comes in, muting the incoming signal on the TI Receive block will make the phone stop ringing. Once the caller hangs up, the preset will automatically un-mute the Mute block, making it ready to receive another call.
