In this small how-to we want to document how to implement a VoIP/SIP doorkeeper using the Snom PA1.
Audio Connections
- Connect Line OUT to the Door Phone Speaker
- Connect MIC IN to the Door Phone Receiver
Keyboard Connections
- Key 6 and 7 control Dial Pad Key 1, see also PA-1 Keyboard Matrix
- Connect Key 6 and 7 to the Door Phone Call Button
- From the PA-1 Web User Interface, configure a Speed Dial to an internal Extension and assign it to a Dial Pad Key
- Enable Auto Dial if you wish to dial the number configured under the Speed Dial automatically
Alternatively, you can use any combination of keys or single Dial Pad Key:
 Dial Pad Key  PIN  PIN 0 2 3 1 6 7 2 5 7 3 4 7 4 3 7 5 2 7 6 1 7 7 6 5 8 5 4 9 7 0
Electronic Door Strike Relay
Use I/O Connector 1 or 2 to supply voltage to an Electronic Door Strike.
I/O Connector 1

VDD & I/O Connector 2
Pins 1, 2, 3 and 4 are Normally Open contacts. They can be closed, supplying 3.3vdc, by using remote DTMF or the Web Interface.PIN 1: On 1#, Off 1* PIN 2: On 2#, Off 2* PIN 3: On 3#, Off 3* PIN 4: On 4#, Off 4*
