There are currently two methods to make an extension number call:

Or:
2. Dial the number directly, and press # (assuming that “ Use # as dial key ” is selected in the web configuration).

services.
3.1.4.2 Direct IP calls
Direct IP calling allows two phones to talk to each other in an ad hoc fashion without a SIP proxy.
VoIP calls can be made between two phones, if:
 Both VOIP Client ATA and the other VoIP device (i.e., another VOIP Client ATA or other SIP products) have public IP
addresses, or
 Both VOIP Client ATA and the other VoIP device (i.e., another VOIP Client ATA or other SIP produces) are on the same
LAN using private or public IP addresses, or

Both VOIP Client ATA and the other VoIP device (i.e., another VOIP Client ATA or other SIP products)
can be connected through a router using public or private IP addresses.
To make a direct IP call, first pick up the analog phone or turn on the speakerphone on the analog
phone, then access the voice menu prompt by dial “ *** ” or press the button on the HT286, and dial
“ 47 ” to access the direct IP call menu. User will hear a voice prompt “ Direct IP Calling ” and a dial
tone. Enter a 12-digit target IP address to make a call.
