Class of Service
A Class of Service is used to group PBX extensions. This simplifies the process of assigning telephony functionality,
such as dial plans, to extensions. Each set of telephony options is applied to a Class of Service instead of individual
extensions. The PBX allows you to create up to 9 classes of services. More than one Class of Service can be applied to a
single extension.

For information about applying a Class of Service to an extension, see the Analog Extensions and VoIP Extensions
sections.
For information about assigning a Class of Service to a dial plan, see outgoing calls routing section.
To create a new Class of Service:

Hunt Groups
The L13 PBX features H
unt Groups
for automatic distribution of incoming calls to two or more extensions. This allows
you to set up groups of extensions to handle different types of operations. In this case,
Transfer to Hunt Group
is
added as a menu option in the Edit Incoming Call Routing screen (see section
3.7.3.3).
To define a hunt group:
1.
In the main IP-PBX screen (
Services
Voice
), click the
Hunt Groups
tab. The Hunt Groups screen appears.

Click the
New Hunt Group

Set the parameters as follows:
Parameter
Description
Name
Specify a name for the hunt group.
Ring Mode
Select whether to ring all extensions at once when a call arrives,
(where the first extension that answers, accepts the call), or to ring
one extension at a time. Selecting the second choice will refresh the
screen.
Extensions to Ring
Select the extensions to include in this hunt group. The drop-down
menu displays all available extensions. Note that this step is
mandatory; otherwise the hunt group is empty.
If you chose to ring one extension at a time as your ring mode, by
default the ring will be routed between the extensions in their order
of appearance in this table. When adding multiple extensions, the
and
action icons appear. Use these icons to move the
selected extension up or down in the list. If you chose simultaneous
ringing, the order of extensions is not relevant.

Advanced Telephony Options
This section (
Services
Voice
Advanced
) provides advanced options intended for a technician or a system
administrator.
To Enable / Disable Voice Services(administrator only):
In the
Voice Services
section, set the checkbox in accordance with the required functionality.

To set the local SIP port for IP mini PBX (administrator only):
The local SIP port is the port on L13 that listens to SIP requests from the proxy. By default, port 5060 is used for
SIP signaling of phones connected to the gateway. A common problem occurs when using a SIP agent on the LAN
Page 79 / 122

User’s
Guide
79
(for example, an IP phone). A SIP agent requires port forwarding configuration (refer to Section Port Forwarding,
which uses the same port
—
5060. This multiple use of the port causes failure of either or both services. Therefore,
when configuring port forwarding for a SIP agent, you must change L13 SIP port value (for example, to 5062).
Note that the calling party must be made aware of this value when initiating a direct call (not using a proxy).

SIP
Set SIP related parameters:
Parameter
Description
Local SIP Port
L13 SIP protocol signaling port.
SIP Reconnect Timeout
The timeout for reconnecting the L13 SIP server
from each VoIP extension.
Use Strict SIP Message Checking
By default, L13 uses strict SIP message checking,
which includes checking of tags in headers,
international character conversions in URIs, and
multiline formatted headers. There are cases in
which this option should be disabled to ensure
interoperability with certain service providers or
third party user agents (SIP endpoints).
Enable Silence Suppression
Enables optimization when no speech is detected.
With this feature enabled, L13 is able to detect the
absence of audio and conserve bandwidth by
preventing the transmission of "silent packets" over
the network. By default this option is selected in
L13.
To change the RTP start port (administrator only):
The voice stream is transmitted in Real Time Protocol (RTP) packets, which require a range of open ports. If the
default ports are required for another application, you can enter a different start port, thereby creating a new
range.
Under the
Local RTP Port Range
, specify the first port in the range of 16 ports to reserve for Real Time Protocol
(RTP) voice transport.

RTP
To configure the QoS parameters (administrator only):
Quality of Service (QoS) is aimed at improving the quality of voice traffic over VoIP external line.
In the
Quality of Service
section, configure the following options:

Figure 106: Advanced

Quality of Service
Type of Service (HEX)
This is a part of the IP header that defines the type
of routing service to be used to tag outgoing voice
packets originated from MBR. It is used to tell
routers along the way that this packet should get
specific QoS. Leave this value as 0XB8 (default) if
you are unfamiliar with the Differentiated Services
IP protocol parameter.
Use MSS Clamping to Reduce Voice
Delay
When using Maximum Segment Size (MSS)
Clamping, TCP streams routed via L13 when a voice
call is active, will have a smaller segment size. This
will cause RTP to receive better priority, and will
help prevent high voice jitter that is caused by slow
upstream transmission rate, and which is common
with most WAN connections (DSL, DOCSIS, etc.).
When checking this option, the
Maximum Segment
Size (MSS)
field appears. Change the maximal
segment size as necessary.
To manage voice CODECs (administrator only)
Figure 107: Voice-Codecs selection
To add a codec(administrator only):
The
CODECs
section enables you to add a voice codec for VoIP connections and specify the priority level of each
codec.
1.
In the CODECs section, at the lower left, open the Add CODEC dropdown menu. All available voice codecs
that were not already selected appear in the menu.
2.
Select the codec you want to add. The codec is added to the list of supported codecs.
To change the order of priority of the supported codecs (administrator only):
Use the arrow action icons.
To remove a codec from the list of supported codecs (administrator only):
Click the
action icon.
