• All entered digit sequences have known lengths - 2 digits for menu option and 12 digits for IP
address. Once all of the digits are collected, the input will be processed.
• Incorrect keyed entry cannot be deleted or undone. The GW0221 will prompt you to start over by
telling you that you made an error.
5.2 Make Phone Calls
5.2.1 Calling Phone or Extension Numbers
a) 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
b) Dial the number directly, and press # (assuming that “Use # as Dial Key” is set to “YES” during web
configuration of your GW0221).
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 Direct IP-to-IP Calls
Direct IP calling allows two phones (a GW0221 and another GW0221 or another VoIP device), to call
each without a SIP gatekeeper or proxy server. VoIP calls can be made between two phones without
a VoIP service provider if:

GW0221 User Manual
6/24
• Both GW0221 and the other VoIP device (i.e., another GW0221 or another SIP device) have public
IP addresses, or
• Both GW0221 and the other VoIP device (i.e., another GW0221 or another SIP device) are on the
same LAN using private or public IP addresses, or
• Both GW0221 and the other VoIP device (i.e., another GW0221 or another SIP device) 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 use the handsfree button), and follow
Section 5.1 using menu option “47”. When you hear the voice say, “Direct IP Calling”, enter the
12-digit IP address of the VoIP device you want to call. Destination ports can be specified by using
“*4” (encoding for “:”) followed by the encoded port number. Following is a table of the encoding
scheme for the most commonly used characters:
Input Meaning
00 0
01 1
02 2
03 3
04 4
05 5
06 6
07 7
08 8
09 9
*0 . (dot character)
*4 : (column character)
5.2.2.1 IP-to-IP Dialing Instructions
If the IP address of the device you want to call is 192.168.1.107, then the dialing method is:
Get voice prompt (“Direct IP Calling”) by pressing “***” and then selecting option 47, OR press
the light button twice. Then press 192168001107 followed by pressing the “#” key (if “#” is
configured as a enter/send key during web configuration) or wait 4 seconds. In this case, the
default destination port 5060 of the device you are calling is used if no port is specified.
If the target IP address/port is 192.168.1.107:5062, then the dialing method would be:
Get voice prompt (“Direct IP Calling”) by pressing “***” and then selecting option 47, OR press the
light button twice. Then press 192168001107*45062 followed by pressing the “#” key (if “#” is
configured as a enter/send key) or wait 4 seconds.
5.2.3 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:

GW0221 User Manual
7/24
1. Party A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial
tone.
2. Then party A dials *87 then dials party C’s number, and then # (or wait for 4 seconds)
3. Party A can hang 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:
• 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.
• 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.
• Busy tone keeps playing. This means the GW0221 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.
5.2.4 Attended Transfer
Assuming that call party A and party B are in conversation. Party A wants to attend transfer party B to
party C:
1. Party A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial
tone.
2. Party A then dials party C’s number then # (or wait for 4 seconds). Party A and party C now are
in conversation.
3. Party A can hang up.
Note: When Attended Transfer failed and if party A hangs up, the GW0221 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.
5.2.5 3-Way Conference Calls
Assuming that call party A called party B, and now they are in conversation. Party A wants to let party
C to attend the conversation:
1. Party A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial
tone.
2. Party A then dials *23, then press party C’s number then # (or wait for 4 seconds). Party A and
party C now are in conversation.
3. Party A presses FLASH again, now the 3 parties are all in conversation.
Note: The gatekeeper needs to support this function for this feature or the phones to work.
5.2.6 Make and Receive PSTN Calls

GW0221 User Manual
8/24
Users can send and receive calls from PSTN. To receive PSTN calls, simply pick up the phone
