Once connected, you can dial other devices directly from the application Dial Pad or create a SIP Proxy device, click it to display the device card and start calling. Click 
to start calling. Click the 
icon to send the set DTMF code to the device.

Tip
- Press and hold the lock button to display the lock list (locks 1–4) to control all the locks (not only the default one).
Caution
- It is impossible to send the DTMF code from the application outside a call for technical reasons. Therefore, if you press the lock outside a call in the SIP Proxy mode, a call is set up first during which the DTMF is sent automatically.
- If the 2N IP intercom and the application are in one and the same LAN, the incoming call is always identified as a LAN call even if it goes via a SIP Proxy server. If you require SIP Proxy identification and the application and 2N IP intercom share one and the same LAN, set a different Access Key password in the application.
Tip
- Refer to faq.2n.cz for more details on SIP Proxy server calls.
