2 Call Appearance with 1 SIP Account
GXP1100/1105 can support up to two lines “virtually” mapped to a SIP account. By picking up the handset,
the GXP1100/1105 will be in off-hook state and the dial tone will be heard. To make a call, dial out the
number with the current line. During the call, users can press the FLASH button to hold the current call and
make/answer another call. Users can switch the two lines by pressing the FLASH button.
Completing Calls
The GXP1100/1105 allows you to make phone calls by picking up the handset. There are four ways to
complete calls.
1. D
IAL : To make a phone call.
•Take handset off hook
•The line will have a dial tone
•Enter the phone number
•Press “#” or SEND button to send
2. R
EDIAL :To redial the last dialed phone number.
•Take handset off-hook

Grandstream Networks, Inc. GXP1100/1105 User Manual Page 9 of 29
Firmware version: 1.0.1.80 Last Updated: 07/2011
•Press the SEND key.
3. VIA SPEED DIAL:On the GXP1100/1105, the Multiple Purpose Key (programmable hard key) has to
be configured as Speed Dial and with the correct name and user ID under Web GUI->Basic Settings
configuration.
•Take handset off hook
•Press the configured Speed Dial key
4. VIA CALL RETURN:On the GXP1100/1105, the Multiple Purpose Key (programmable hard key) has to
be configured as Call Return under Web GUI->Basic Settings configuration. No user name and user
ID has to be set on the Multiple Purpose Key for Call Return. After pressing the Call Return key, the
last answered number will be dialed out.
•Take handset off hook
•Press the configured Call Return key
NOTE:
1. Dial tone occurs after the handset is off-hook. After dialing the number, the phone waits 4 seconds (by
default; No key Entry Timeout) before sending and initiating the call. Press “#” button to override the 4
second delay.
2. If there are digits pressed, the SEND key will work as SEND instead of REDIAL.
Making Calls using IP Addresses
Direct IP Call 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 phones have public IP addresses, or
•Both phones are on a same LAN/VPN using private or public IP addresses, or
•Both phones can be connected through a router using public or private IP addresses (with necessary
port forwarding or DMZ)
To make a direct IP call, please follow these steps:
•Take handset off
•After hearing the dial tone, press “***” to enter the IVR menu
•Enter “47” for Direct IP Call. After hearing “Direct IP Calling”, the dial tone will be heard again
•Enter the target IP address. (Please see example below)
•Wait for about 4 seconds and the phone will initiate the call
For example: If the target IP address is 192.168.1.60 and the port is 5062 (e.g. 192.168.1.60:5062), input
the following: 192*168*1*60#5062. The “*” key represents the dot “.”; the “#” key represents colon “:”. Wait
for about 4 seconds and the phone will initiate the call.
The GXP1100/1105 also supports Quick IP Call mode. This enables the phone to make direct IP-calls, using
only the last few digits (last octet) of the target phone’s IP-number. This is possible only if both phones are in
under the same LAN/VPN. This simulates a PBX function using the CMSA/CD without a SIP server.
Controlled static IP usage is recommended.
To enable Quick IP calls, the phone has to be setup first. This is done through the web-setup function. In the
“Advanced Settings” page, set the "Use Quick IP-call mode” to “Yes”. Then take the handset offhook and dial

Grandstream Networks, Inc. GXP1100/1105 User Manual Page 10 of 29
Firmware version: 1.0.1.80 Last Updated: 07/2011
#xxx where x is 0-9 and xxx <=255. A direct IP call to aaa.bbb.ccc.XXX will be completed. “aaa.bbb.ccc” is
from the local IP address regardless of subnet mask. The numbers #xx or #x are also valid. The leading 0 is
not required (but OK).
For example:
192.168.0.2 calling 192.168.0.3 -- dial #3 followed by #
192.168.0.2 calling 192.168.0.23 -- dial #23 followed by #
192.168.0.2 calling 192.168.0.123 -- dial #123 followed by #
192.168.0.2: dial #3 and #03 and #003 results in the same call -- call 192.168.0.3
NOTE:
1. The “#” will represent colon “:” in Direct IP Call instead of Send key as in normal phone call
2. If you have a SIP Server configured, a Direct IP-IP still works. If you are using STUN, the Direct IP-IP call
will also use STUN. Configure the “Use Random Port” to “No” when completing Direct IP calls.
ANSWERING PHONE CALLS
Receiving Calls
1. Incoming single call: Phone rings with selected ring-tone. Answer call by taking Handset off hook.
2. Incoming multiple calls: When another call comes in while having an active call, the phone will
