Time Zone Specify the time zone that the handset uses to compute its
local time. Select the use current server setting if the port
expander is in the same time zone as the server. For a
remote port expander, you may want to use the time zone of
its actual location.
Daylight Savings Time Specify if the port expander will use Daylight Savings Time
(DST) to compute its local time. Select use current server
setting if the port expander is in the same time zone as the
server. For a remote port expander, you may want to use the
DST setting of its actual location.
Jitter Buffer Size Alter the size of the jitter buffer. Jitter is a variation in network
audio packet latency experienced by the port expander,
resulting in a reduction in audio quality. The port expander
uses a jitter buffer to maximize the audio quality when jitter
occurs.
13.5.2 Configuring FXO and FXS Ports
After installing an Allworx Port Expander, the Allworx Server Administrator can
configure the FXS and FXO ports on the Handsets and Outside Lines pages, just like
the server’s own ports. On the Dial Plan page, the system adds port expander FXO
ports to the default service groups. The system enables creating new custom service
groups or modifying existing groups to include the port expander’s FXO ports.
13.6 Outside Line Call Routing
Each outside line (CO Line, DID Line, SIP Proxy, SIP Gateway, or a Digital Line) has a
call route associated with it. Go to Phone System > Outside Lines and click the
Modify link on one of the CO lines. The Outside Lines page displays.
The Call Route section in the figure above directs the call coming into the system
through Digital Line 1 channel 01.
Call route Description
Extension Routes incoming calls to a User or System extension.
Using a System Extension provides more call routing
flexibility and enables using a common route for multiple
lines.
Auto Attendant Routes an outside line to an Auto Attendant, it goes to
the designated Auto Attendant that defined in the Default
Auto Attendant section.
Voicemail for user Calls that come into the System would go directly to a
voicemail box for a User.
Routed using DID Block(s) When using DID blocks for incoming calls, the DID block
has to be enabled for the outside line or each desired
channel, if using digital lines (See Chapter 22, Direct
Inward Dialing (DID). for more information).
