2.4.9.2 Point-to-Point Configuration
When the device is set to not register with a SIP server (see
), it is possible to set the
device to dial out to a single endpoint.
In this case, the dial-out extension should be the IP address of the remote device. The device can
also receive Point-to-Point calls. The delayed DTMF functionality is available in the Point-to-Point
Mode.
Note
Receiving point-to-point SiP calls may not work with all phones.

2.4.9.3 Delayed DTMF
On the

pauses and sending additional DTMF tones (using rfc2833). The first comma will pause three
seconds after a call is first established with a remote device. Subsequent commas will pause for 2
seconds. A pause of one second will be sent after each numerical digit.
