5. System Configuration
The Voice Gateway / Pocket Voice Gateway can be configured in many
ways such as using telnet, Web browser, telephone keypad, or SNMP control. Although there are many VoIP protocols, Voice Gateway currently supports H.323 protocol and MGCP protocol.
For H.323 protocol, it can support both version 2 and version 3.
For MGCP protocol, Voice Gateway can support most major profiles to
achieve maximum interoperability . This includes RFC standard profile (RFC
2705, MGCP 1.0), NCS standard profile (for Packet Cable, NCS 1.0), and
some proprietary profile (MGCP 0.1, NCS 1.0).
The following sections describe all methods for controlling Voice Gateway.
5.1. Console Control

5. System Configuration
5.2. Telnet Control
The Voice Gateway can be controlled by Telnet applications. This capability is disabled when the voice gateway is already controlled from the console. Users may access all console commands using Telnet.
5.2.1. Establish Connection
T elnet can be used to enter the console control mode. The parameters of the
factory default are shown below. The default values using Telnet are:
IP Address = 192.168.100.100
Netmask = 255.255.255.0
Default Gateway = 192.168.100.254
You have to also enter a username (default “voip”) and password while you
use T elnet to connect to the system. The default password using T elnet is the
same as the console control input (last 6 lowercase characters of the Ethernet MAC address). The console mode using the console cable has a higher
priority than using Telnet. Therefore, the Telnet user cannot enter control
mode while another computer has control through the console port. If a
currect T elnet session is active, it will be disconnected when a connection is
started through the console port. Except priority levels, there are no differences in commands when accessing through Telnet or the console port.
5.3. Web (HTTP) Console
Users can use browsers to setup or
show the information of the voice
gateway . For example, they can use
Internet Explorer to configure the
telephone number of VoIP phone.
The IP address of the Web console
is the same as the IP address used
by Telnet.
The web page is divided into several frames, each of which is related to a
VoIP module. It includes system settings, H.323 or MGCP settings, and
About. Users can follow the procedures listed below to set up Voice Gateway.

5.4.2. Supplemental Services Commands
Currently, the VoIP products of support the following basic supplemental
services.
Automatic Callback (**66)
Automatic Callback allows a subscriber to initiate a call set up to the last
directory number that was dialed from the subscriber’s line so that the number is dialed automatically without the subscriber having to redial.
Automatic Redial (**69)
Automatic Recall allows a subscriber to automatically call back the last
number that called the subscriber’s directory number , whether the subscriber
answered the call or not. To activate the AR feature, the subscriber needs to
go off hook, waits for a dial tone, and dials a feature activation code (**69).
Speed Calling (**74 + one digit (2 – 9))
Speed calling permits the subscriber to dial selected directory numbers using fewer digits than normally required. This is accomplished through the
assignment of one-digit code to frequently called directory number. Subscribers are allowed to assign eight directory numbers to the Speed Calling
List (2 through 9).
Distinctive Ringing (**61)
Distinctive Ringing allows the subscriber to manage incoming calls by designating special directory numbers that may be identified using distinctive
ringing patterns. Currently the VoIP gateway supports Fast/Normal/Slow
Ringing. The Ring On/Off Patterns are On-1s, Off-1s (Fast mode)/On-2s,
Off-1s (Normal Mode)/On-1s, Off-2s (Slot Mode).
Inner Conference Call (***1-4)
The VoIP products of with multiple phones can support an extra service for
inner phones conference. Each user under the same Voice Gateway can call
each other without any Internet connectivity. For example, the user in the
phone 1 can dial ***3 to the user in the phone 3 directly.

7. System Operation
Voice Gateway / Pocket Voice Gateway products can be operated in two
modes: H.323 voice gateway and MGCP voice gateway. The system requirements are different in H.323 and MGCP environments.
7.1 H.323 Notes
Yes?
Dial IP or E.164
through GK
Yes?
Dial IP or E.164
through GW
H.323 is a peer-to-peer connection protocol for VoIP . In an H.323 environment,
you can make a phone call to the destination directly, or though an H.323
gatekeeper and/or a trunk gateway . Then,
you can make a phone call by either an
IP address or a telephone number (E.164
number). Therefore, in our configuration,
users have to setup the strategy to make
a phone call. The criterion follows the
rule:
GK?
No?
GW?
No?
Dial IP only
Make an H.323 phone call to other H.323 VoIP terminal (if H.323 firmware
exists)
1. Call to pure VoIP (non-E.164 telephone) terminal
a. Pick up phone. After hearing a dial tone, dial the IP address of the
peer terminal. Here you have to use star (*) as dot (.), and then press
hash (#) to end. For example, if the IP address of the peer terminal is
192.168.100.2 then you have to press 192*168*100*2#
2. Call to E.164-addressed telephone terminal
a. In this environment, you have to connect to an H.323 Gatekeeper or
Gateway to support E.164 address or IP Address.
b. You can use one of the user interfaces to configure the IP address of
the H.323 Gatekeeper or Gateway. Refer to Chapter 5 for the configuration interface.
After you setup the IP address of the Gatekeeper and phone number of each
line, you can dial to the peer terminal as in a standard telephone. For example, if you want to dial to 7123456 then you just press 7123456# to make
this phone call.

7. System Operation
7.2 MGCP Notes
MGCP is a client-server connection protocol of V oIP technology . In an MGCP
environment, it is compulsory for a server (named Call Agent or Call Manager) to manage and control all MGCP clients. Different Call Agents may
employ different MGCP profiles, which define the procedures and parameters of a VoIP phone call.
Voice Gateway / Pocket Voice Gateway can support RFC standard profiles
(RFC2705, MGCP 1.0), NCS standard profile (Packet Cable), and some
proprietary profile (MGCP 0.1, NCS 1.0).
While the operator will set up the call agent with IP phone information,
users have to set up the Voice Gateway with a valid IP address, the IP address (or domain name) of the Call Agents, and the corresponding MGCP
profile.
In an MGCP environment, all clients need to use E.164 number to start the
connection. The mapping of an E.164 number and IP address is handled by
the MGCP Call Agent, then a user can call a peer VoIP terminal by the
E.164 number . You can simply make a phone call as in standard telephones.
For example, if you want to dial to 7123456 , you press 7123456 to make
the phone call.
7.3 Application Examples
The voice gateways can be configured to perform many roles to support
various demands from customers. Here, it presents some application examples for customer to know how to configure the voice gateway.
7.3.1 VoIP Voice Gateway to VoIP Networks using IP address
The first simple example shows the use of the Ethernet WAN port to connect to a VoIP network. The other LAN port connects to another computer.
One or more telephone directly connects to the FXS interfaces (P1, P2 …
or Phone). This example provides you simple VoIP phone to another VoIP
phone (VoIP to VoIP).

You can check the following items to make sure your configuration setting
is correct. If you cannot have the correct result, please check the User Menu
to see more details about system setting. Or you can connect to our customers support to inquire the setting.
a. Use inner conference call to make phone call between each phones on
the voice gateway:
- Pick up one of telephone set, you will hear the dial tone.
- Then dial ***1 to ***4 (for 4 ports) to make phone call to another one.
- If the one is on-hook, voice gateway will ring the telephone. Pick up
the phone, then the phone call establish well.
- If the one is already in use then you will hear busy tone.
b. Make the VoIP phone to VoIP Networks
- Pick up one of telephone set, you will hear the dial tone.
- Then the IP address of called party. For example, if you want to dial
VoIP phone to 192.168.100.102, you have to dial 192*168*100*102#.
- If called party is available then you will hear ring back tone. And if
he accept the call, the phone call establish well.
- If the one is already in use then you will hear busy tone.
c. For H.323 phone in this case, you cannot dial E.164 telephone number
(the traditional telephone number, like the one as your cell phone). And
for multiple ports voice gateway , you cannot make VoIP phone to specified port. For example, you cannot dial to P2 directly without any setting. The P2 will receive the call only when P1 is already in use. But you
can use other port (P2, P3, P4) to dial out without any limitations.
d. For MGCP phone, you need Call Agent to control the MGCP phone.
Therefore, you cannot dial IP address in this example.

7.3.2 V oIP V oice Gateway to V oIP Networks using E.164 telephone number without VoIP Server
Since there are some limitations in the first example, our Voice Gateway
supports another features to provide E.164 numbers’ call without server. If
another party (caller/called) of VoIP phone can support this feature also,
then the both parties can use this function to dial the VoIP phone as the
traditional telephone servers. Please refer to user menu to setup the H.323
telephone number mapping (show_maptab and set_map_tab commands in
H.323 command directory)

a. This example can support all features in the previous example. It means
you can dial VoIP phone using IP address and E.164 number co-existed.
b. Y ou have to configure the mapping table according above in both caller/
called parties. For example, you have already setup the following mapping table:
Index Telephone IP Address
0 1011 192.168.100.101
1 1012 192.168.100.101

3 1014 192.168.100.101
4 1021 192.168.100.102
c. From another VoIP phone, you can dial 1012# to make the phone call to
the second port of Voice Gateway. You can dial to second port directly
even port one is also available for the call.
d. Here, we mention again. For MGCP phone, it needs Call Agent to control
it. Therefore, you cannot dial VoIP phone to others. The voice gateway
can support inner conference call only without controlling from Call Agent.

In order to dial out to PSTN world, the VoIP system has to connect to trunk
gateway to PSTN controlled by VoIP Server . For example, you have to connect to Call Agent or Gatekeeper. Then you can dial to PSTN using VoIP
phone.
a. You have to setup the VoIP phone is controlled by Sever first in this
example.
b. For H.323, you have to enable Gatekeeper function in the H.323 com-
mand directory . And setup the IP address of Gatekeeper. Some vendor’s
trunk gateway supports E.164 numbering function but does not support
Gatekeeper functionality, please enable trunk gateway and disable
Gatekeeper in H.323 command directory.
c. For H.323, the voice gateway has to setup the telephone number itself.
Please use the set_phno command in H.323 command directory to set
them.
d. For MGCP, you have to setup the IP address of Call Agent. Then you
have to setup the DNS name of the voice gateway. The similar setting
have to support in setting of Call Agent. Then the voice gateway can
make phone call well.
e. If the voice gateway cannot connect to server well, you still can use the
function of inner conference call. So, you can hear the dial tone also
while you pick up the phone. By the way, if you want to dial out, you
will hear busy tone since it cannot connect to VoIP server.
f. For H.323, you can also dial to VoIP phone using IP address without
connecting to VoIP server.

7.3.4 VoIP Voice Gateway to VoIP Networks with PSTN line
The voice gateway of also support FXO interface to PSTN world directly.
Three models of voice gateway support this function. AVG6001BA and
AVG6001BD support one FXO interface. AVG6004BA support four FXO
interfaces. Here is the example to support PSTN line and you can dial to
traditional phone using our VoIP voice gateway.
Due to the variety of telephony specification, the FXO interface of voice
gateway has to commit the specification very well. For example, you have
to setup the call progressive tone of the PSTN line from Telephone companies or PBX. Please contact to our Technical Service to inquire the details
specification of PSTN line in different countries and different PBX.
a. The function of P2 (or P3 and P4 in 4 ports model) is as same as all the
examples above.
b. To provide PSTN backup functionality, you can use inner conference
call to make a PSTN phone out. Just dial ***1, you can hear the second
tone. Then you can dial the E.164 telephone number to real PSTN world.
User can also configure the PSTN line port using E.164 number, for
example 1011. Then after all other VoIP phone dial to 1011, the second
tone can be hear . Then user can also dial the telephone number to PSTN
world. Here, this voice gateway can be treated as a translation (so called
gateway) between VoIP phone and PSTN phone.
c. Vice verse, the user at PSTN world can dial to this PSTN line. After
second ring, the voice gateway will pick up the phone and send the second dial tone again. Then user can also dial to VoIP phone using IP
address or E.164 telephone number that is described in previous section.
