8.3.2.3 QoS&VLAN
The VOIP phone support 802.1Q/P protocol and DiffServ configuration.
VLAN functionality can use different VLAN IDs by setting voice VLAN and
data VLAN. The VLAN application of this phone is very flexible.
Page 33
User Manual
SPEEDYTEL Technology CO Ltd
In chart 1, there is a layer 2 that switches without setting VLAN. Any
broadcast frame will be transmitted to the other ports except the send port.
For example, a broadcast information is sent out from port 1 then
transmitted to port 2,3and 4.
In chart 2, red and blue indicate two different VLANs in the switch, and
port 1 and port 2 belong to red VLAN, port 3 and port 4 belong to blue
VLAN. If a broadcast frame is sent out from port 1, switch will transmit it
to port 2, the other port in the red VLAN and not transmit it to port3 and
port 4 in blue VLAN. By this means, VLAN divide the broadcast domain via
restricting the range of broadcast frame transition.
Note: chart 2 use red and blue to identify the different VLAN, but in
practice, VLAN uses different VLAN IDs to identify.

8.3.3.4 DIAL PEER
This functionality offers you more flexible dial rule, you can refer to the
following content to know how to use this dial rule. When you want to dial
an IP address, the entry of IP addresses is very cumbersome, but by this
functionality, you can set number 156 to replace 192.168.1.119 here.
When you want to dial a long distance call to Beijing, you need dial an area
code 010 before local phone number, but you can also dial number 1
instead of 010 after we make a setting according to this dial rule. For
example, you want to dial 01062213123, but you need dial only
162213123 to realize your long distance call after you make this setting.
To save the memory and avoid abundant input of user, add the follow
functions:
1. Increase in x matches any single digit, for example:
If user makes the above configuration, after user dials 11 digit numbers
started with 13, the phone will send out 0 plus the dialed numbers
automatically.
2. [] Specifies a range that will match digit. It may be a range, a list of
ranges separated by commas, or a list of digits.

If user makes the above configuration, after user dials 11 digit numbers
started with from 135 to 139, the phone will send out 0 plus the dialed
numbers automatically.
Use this phone you can realize dialing out via different lines without
switch in web interface.
DIAL PEER
Field name
explanation
Phone number
There are two types of matching conditions: one is
full matching, the other is prefix matching. In the
Full matching, you need input your desired phone
number in this blank, and then you need dial the
phone number to realize calling to what the phone
number is mapped. In the prefix matching, you
need input your desired prefix number and T; then
dial the prefix and a phone number to realize
calling to what your prefix number is mapped. The
prefix number supports at most 30 digits.
Destination
Set Destination address. This is optional config
item. If you want to set peer to peer call, please
input destination IP address or domain name. If
you want to use this dial rule on SIP2 line, you need
input 255.255.255.255 or 0.0.0.2 in it.SIP3 into
0.0.0.3
Port
Set the Signal port, the default is 5060 for SIP.
Alias
Set alias. This is optional config item. If you don’t
set Alias, it will show no alias.
Note: There are four types of aliases.
Page 53
User Manual
SPEEDYTEL Technology CO Ltd
1) Add: xxx, it means that you need dial xxx in front of phone number,
which will reduce dialing number length.
2) All: xxx, it means that xxx will replace some phone number.
3) Del: It means that phone will delete the number with length
appointed.
4) Rep: It means that phone will replace the number with length and
number appointed.
You can refer to the following examples of different alias application to
know more how to use different aliases and this dial rule.
Call Mode
Select different signal protocol, SIP or IAX2
Suffix
Set suffix, this is optional config item. It will show
no suffix if you don’t set it.
Delete Length
Set delete length. This is optional config item. For
example: if the delete length is 3, the phone will
delete the first 3 digits then send out the rest digits.
You can refer to examples of different alias
application to know how to set delete length.
The following describes how to configure the number IP table to achieve the
configuration of multiple accounts simultaneously:
9T means when you configure the SIP1 server and register, then the user
through all SIP1 call to dial a 9 before the number；
8T means when you configure the SIP2 server and register, then the user
through all the numbers before calling SIP2 dial 8；
2T means when you configure the IAX2 server and register, then the user
through all the IAX2 protocol number before the call can dial 2.
Note: For compatibility with 1.6 functions in the 1.7 version of the
configuration file, add "Dialpeer With Line:" This field indicates whether to
enable the on-line inquiry function, 0 is not enabled, 1 means enabled. The
default is 0.
Differences are as follows:
1. Not enabled on-line inquiry
The function and the 1.6 version of the function is the same.
Type: This rule indicates what protocol needs to go.
Destination: indicates the destination address.
0.0.0.1 represents go sip1 line
0.0.0.2 represents go sip2 line
0.0.0.x represents go sipx line
(For compatibility with old code 0.0.0.0 means go sip1 line, 255.255.255.255
Page 54
User Manual
SPEEDYTEL Technology CO Ltd
indicates go sip2 line)
Configuration examples are as follows:
If the phone dial 21111, the fact is through SIP2 and called number is 1111.
If the phone dial 32222, the fact is through IAX2 and called number is 2222.
2. Enable on-line query capabilities
Enable on-line query function on the premise that: The phone must be
multi-line products, you can choose when dialing protocol and line. So that
each end of the dial, and also selected protocol and line.
Dialpeer table in the query, the first comparison dialing protocol is selected in
the table and dialpeer agreement, if the same, continue down the match,
otherwise, check the next one.
Step match line information, comparing the selected dial-up line is a line in the
table and dialpeer is the same, if the same, continue down the match,
otherwise the next query.
The third step is for a prefix or exact match.
Mode: to sip, it means that this rule is only used for sip protocol calls; iax2, it
means that this rule is only used iax2 protocol calls.
Destination: indicates the destination address.
0.0.0.1 Indicates that the rule only calls for sip1 online
0.0.0.2 Indicates that the rule only calls for sip2 online
0.0.0.x Indicates that the rule only calls for sipX online
0.0.0.0 Indicates that the rules used in all online calls
Configuration Application examples
The handset off-hook exhale (if SIP1 registration is successful, the default is
SIP1) If the dial 21111, then exhaled directly through SIP1 and the called
number is 21111
If the phone off-hook exhale (if SIP1 registration is successful, the default is
SIP1) If dialing 32222, directly and through SIP1 outgoing called number is
32222
To make the configuration take effect dialpeer function,
Only when the handset off-hook exhaled choose SIP2, and dials 21111, the
corresponding rule is matched by SIP2 exhaled and the called number is 1111
Only when the handset off-hook exhaled Select IAX2, and dials 32222, the
corresponding rule is matched by IAX2 outgoing and called number is 2222

In order to make some intranet equipment support better service for
extranet, and make internal network security more effectively, these
equipment open to extranet need be separated from the other equipment
not open to extranet by the corresponding isolation method according to
different demands. We can provide the different security level protection
in terms of the different resources by building a DMZ region which can
