This section provides a step-by-step guide to install the MTA8328 and setup the system for connecting to a
broadband network. Before starting the Installation, make sure your broadband Internet access device is
powered on and your connection is up (chek ou Iteet seie poides douetatio.

1. Plug the supplied power adapter into the MTA8328. The power LED will show steady green.
2. Connect your phone into the PHONE port on the MTA using the supplied Phone Cable.
3. Setup the MTA to connect to your Home Router. Connect the yellow Ethernet cable (supplied) into
the WAN port on the MTA and connect the other end into an available Ethernet port on your router
or LAN network.
4. If you have a device with Wifi, use the Captive Portal method to configure the the Wifi portion of the
device and connect it to you home router.
a. Press the round button on the device for more than 5 secs
b. Use your mobile device o laptop to disoe the ““ID MTA hee the  ae
last 4 digits of your device MAC address
c. Connect to that SSID and configure your device with the appropriate pass phrase and
complete the Wifi setup of your device
5. Confirm that the MTA is successfully connected to the router and has acquired an IP address by
checking that the WAN LED shows green for a 100BT connection, or amber for 10BT.
6. Once the MTA connects to the voice service provider network, and completes the registration and
service provision process, you should see a solid green PHONE LED light displayed.

outbound proxy server setting.
SIP Domain
The MTA uses this setting to (1) compose
the host part of SIP request URI strings (2)
perform NAPTR/SRV queries.
Access Network
Info
This header is useful in SIP-based networks
that also provide layer 2/layer 3 connectivity
through different access technologies. SIP
User Agents may use this header to relay
information about the access technology to
proxies that are providing services.
Allowed for Reg.
Retry
Treat the configured return SIP error codes
as successful SIP OPTIONS responses. If
multiple error codes are allowed, use a
comma (,) to separate them.
SIP Ping Proxy
MTA sends SIP OPTION ping messages to an
assigned server as a keep-alive message.

100rel Support
Enable 100rel response support.
Enable Switching
Proxy in Response
to DNS SRV Priority
Change
When this item is enabled, whenever the
MTA is ready to send a REGISTER request
and the SRV TTL has expired, it performs an
SRV query and the MTA will switch to the
most preferred SIP server (lowest priority) in
the SRV query response.
If this item is disabled, the MTA stays with
the currently registered SIP proxy and only
saves the SRV query results. However, if the
current SIP proxy is unreachable, or the MTA
reboots and starts a new DNS query process,
the MTA will then register to the most
preferred SIP server (lowest priority) in the
SRV query response.
Disable rport
Support
Do not append rport (response port
number) in the Via header.
Using Notify for
Flash Support
Send a SIP NOTIFY hook flash event message
during the call when a hook flash is
detected.
Using Info Flash
Support
Send a SIP INFO hook-flash event message
during the call when a hook flash is
detected.
Short header
Support
Send SIP Headers in short format (compact
form) to reduce message packet size.
Enable Re-
registration
Credential
Enable Re-registrations to carry the previous
successful authentication credentials.
OutOfBand DTMF

Use SIP INFO to send DTMF.
RFC2833 DTMF
Use RFC2833 for sending DTMF digits.
Available options:
 Negotiated –MTA and SIP Server
negotiate if 2833 is enabled or not.
 Always off –2833 is never used.
 Always on –2833 is always used.
Send UA Header
Allow MTA to send User-Agent Header in SIP
message.
UA Header Format
User-Agent Header sent out is modifiable.

When this feature is enabled, the MTA
checks all incoming SIP request messages for
their source IP addresses. If the source IP is
not in the SIP Server list, the MTA rejects
or drops this message.
The MTA creates a SIP Server listwhich
