5.2.Make Phone call
5.2.1. Calling Phone or Extension Numbers
Dial the number directly and wait for 4 seconds (Default is 4 seconds. To change the
default, change the settings via the web configuration page under “No Key Entry
Timeout”). Or
Dial the number directly, and press # (assuming that “Use # as Dial Key” is set to “YES”
during web configuration of your Unicorn 3112).
Other functions available during the call are call-waiting/flash, call-transfer, and
call-forward. Your SIP gatekeeper/proxy server needs to support these features in order
for them to work.
5.2.2. Call Hold
While in conversation, pressing the “FLASH” button on the attached phone will put the
remote end on hold. Pressing the “FLASH” button again will release the previously Hold
party and the bi-directional media will resume.
5.2.3. Call Waiting
If call waiting feature is enabled, while the user is in a conversation, he will hear a special

Unicorn 3112 User Manual

stutter tone if there is another incoming call. User can press the flash button to put the
current call party on hold and switch to the other call. Pressing flash button toggles
between two active calls.
5.2.4. 3-way Conferencing
Unicorn3112 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 Unicorn3112 and other VoIP Device, have public IP addresses, or
2. Both Unicorn3112 and other VoIP Device are on the same LAN using private IP
addresses, or
3. Both Unicorn3112 and other VoIP Device can be connected through a router using
public or private IP addresses (with necessary port forwarding or DMZ).
Unicorn3112 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

Unicorn 3112 User Manual
Copyright © 2008 Hanlong Technology Co., Ltd Page 10 of 42
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
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 3112 has failed to receive the

Unicorn 3112 User Manual
Copyright © 2008 Hanlong Technology Co., Ltd Page 11 of 42
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 3112 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. Send and Receive PSTN Calls
Users can send and receive calls from PSTN. To receive PSTN calls, simply take the
phone off hook when the analog phone rings. To make a PSTN call, first press *00 (or
your own PSTN Access Code) to get the PSTN line dial tone and dial the PSTN number.
5.2.9. VoIP-to-PSTN Calls
To make a VoIP-to-PSTN call, users need to dial the FXO SIP account phone number first.
A ring tone is played once followed by a dial tone. At this time, users can dial a PSTN
telephone number or a mobile telephone number then # (or wait for 4 seconds). The call
will be established afterwards. If no PSTN number is entered after the dial tone, Unicorn
3112 will hang up automatically in 10 seconds.
In the web configuration page, if the Route to PSTN field is configured, the second stage
dialing is eliminated. That is, after users dial the FXO SIP account number, the PSTN
number will be called automatically.
5.2.10. PSTN-to-VoIP Calls
To make a PSTN-to-VoIP call, PSTN callers need to originate a call to the FXO port

Unicorn 3112 User Manual
Copyright © 2008 Hanlong Technology Co., Ltd Page 12 of 42
telephone number first. If no one answers the FXS phone after 4 (default value, can be
configured) ring tones, a dial tone is played. At this time, users can dial a VoIP telephone
number then # (or wait for 4 seconds). The call will be established afterwards. If no VoIP
number is entered after the dial tone, Unicorn 3112 will hang up automatically in 10
seconds.
In the web configuration page, if the Route to VoIP field is configured, the second stage
dialing is eliminated. That is, after users dial the FXO port telephone number, the VoIP
number will be called automatically.
5.2.11. Route Calls to PSTN
If configured, certain calls will be routed to PSTN line automatically. This call feature is
especially useful for emergency calls or local telephone calls. To use this feature, users
need to specify a prefix or a telephone number in the Route to PSTN field in the web
configuration page. If the dialed digits match one of the specified prefix, outbound calls will
be routed to PSTN port.
