between two active calls.
5.2.4 3-way Conferencing
Unicorn3101 supports 3-way conference in two styles: star code style or Bellcore style.
Star Code Style 3-way Conference
Assuming that call party A and B are in conversation. A wants to bring C in a conference:
1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a
dial tone.
2. A dials *23 then C’s number then # (or wait for 4 seconds).
3. If C answers the call, then A press “flash” to bring B, C in the conference.
4. If C does not answer the call, A can press “flash” back to talk to B.
Bellcore Style 3-way Conference
Bellcore style 3-way conference is also supported. To do this, user needs to enable “Use
Bell-style 3-way Conference” in FXS web configuration.
Assuming that call party A and B are in conversation. A wants to bring C in a conference:
1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a
dial tone.
2. A dials C’s number then # (or wait for 4 seconds).
3. If C answers the call, then A press “flash” to bring B, C in the conference.
4. If C does not answer the call, A can press “flash” back to talk to B.
5.2.5 Direct IP-to-IP Calls
Direct IP calling allows two parties, that is, a FXS Port with an analog phone and another
VoIP Device, to talk to each other in an ad hoc fashion without a SIP proxy.
Elements necessary to completing a Direct IP Call:
1. Both Unicorn3101 and other VoIP Device, have public IP addresses, or
2. Both Unicorn3101 and other VoIP Device are on the same LAN using private IP
addresses, or
3. Both Unicorn3101 and other VoIP Device can be connected through a router using
public or private IP addresses (with necessary port forwarding or DMZ).
Unicorn3101 supports two ways to make Direct IP Calling:
Using IVR
1. Pick up the analog phone then access the voice menu prompt by dial “***”
2. Dial “47” to access the direct IP call menu
3. Enter the IP address using format ex. 192*168*0*160 after the dial tone.
Using Star Code
1. Pick up the analog phone then dial “*47”
2. Enter the target IP address using same format as above.
Note: NO dial tone will be played between step 1 and 2.
Destination ports can be specified by using “*” (encoding for “:”) followed by the port

Unicorn 3101 User Manual

number.
Examples:
a) If the target IP address is 192.168.0.160, the dialing convention is
*47 or Voice Prompt with option 47, then 192*168*0*160.
followed by pressing the “#” key if it is configured as a send key or wait 4 seconds. In this
case,the default destination port 5060 is used if no port is specified.
b) If the target IP address/port is 192.168.1.20:5062, then the dialing convention would be:
*47 or Voice Prompt with option 47, then 192*168*0*160*5062 followed by pressing the
“#” key, if it is configured as a send key or wait for 4 seconds.
NOTE: When completing direct IP call, the “Use Random Port” should set to “NO”.
5.2.6 Blind Transfer
Assuming that call party A and party B are talking to each other on the phone. Party A
wants to transfer party B to party C:
Party A presses FLASH (on the analog phone, or Hook Flash for old model phones) to
get a dial tone.
Then party A dials *87 then dials party C’s number, and then # (or wait for 4 seconds)
Party A can hangs up the phone.
Note: Call features have to be activated during web configuration by selecting YES to
“Enable Call Features”. These features need to be supported by your
SIP gatekeeper/proxy server in order to work.
Party A can hold on to the phone and wait for one of the three following events:
1. A quick confirmation tone (temporarily using the call waiting indication tone) followed
by a dial tone.This indicates the transfer is successful (transferee has received a 200
OK signal from transfer target). At this point, party A can either hang up or make
another call.
2. A quick busy tone followed by a restored call (on supported SIP
gatekeeper platforms only). This means the transferee has received a 4xx
response signal for the INVITE and will try to recover the call. The busy tone is just to
indicate to the transferor that the transfer has failed.
3. Busy tone keeps playing. This means the Unicorn 3101 has failed to receive the
second NOTIFY signal from the transferee and decided to time out.
Note:this does not indicate the transfer has been successful, nor does it indicate the
transfer has failed. When transferee uses a device that does not support the second
NOTIFY signal, this will be the case. In poor or unstable network scenarios, this could also
happen, although the transfer may have been completed successfully.

5.2.7 Attended Transfer
Assuming that call party A and party B are in conversation. Party A wants to Attend
Transfer party B to party C:
Party A presses FLASH (on the analog phone, or Hook Flash for old model phones) to
get a dial tone.
Party A then dials party C’s number then # (or wait for 4 seconds). Party A and party C
now are in conversation.
Party A can hang
Note: When Attended Transfer failed and if party A hangs up, the Unicorn 3101 will ring
party A again to remind party A that party B is still on the call, by pressing FLASH or Hook
again will restore the conversation between party A and party B.
5.2.8 Make and Receive PSTN Calls
Users can send and receive calls from PSTN. To receive PSTN calls, simply pick up the
phone receiver (or use handsfree) when the analog phone rings. To make a PSTN call,
first press *00 (*00 is default. You can change the “PSTN Access Code” via the web
configuration screen) to get the PSTN line dial tone and then dial the PSTN number you
want to call.

Call Progress Tones
Using these settings, users can configure tone
frequencies and cadence according to their preference.
By default they are set to North American frequencies.
Configure these settings with known values to avoid
uncomfortable high pitch sounds. ON is the period of
ringing (“On time” in ‘ms’) while OFF is the period of
silence. In order to set a continuous tone, OFF should be
zero. Otherwise it will ring ON ms and a pause of OFF ms
and then repeat the pattern.
Example configuration for N.A. Dialtone:
f1=350@-13,f2=440@-13,c=0/0;
Syntax: f1=freq@vol, f2=freq@vol,
c=on1/off1-on2/off2-on3/off3; [...] (Note: freq: 0 - 4000Hz;
vol: -30 - 0dBm)

NAT Traversal
This parameter defines whether the Unicorn 3101 NAT
traversal mechanism will be activated or not. If activated
(by choosing Yes) and a STUN server is also specified,
then the Unicorn 3101 will behave according to the
STUN client specification. Under this mode, the
embedded STUN client inside the Unicorn 3101 will
attempt to detect if and what type of firewall/NAT it is
sitting behind through communication with the specified
STUN server. If the detected NAT is a Full Cone,
Restricted Cone, or a Port-Restricted Cone, the Unicorn
3101will attempt to use its mapped public IP address
and port in all its SIP and SDP messages. If the NAT
Traversal field is set to “Yes” with no specified STUN
server, the Unicorn 3101will periodically (every 20
seconds or so) send a blank UDP packet (with no
