===== Seven Digit Dialing =====

{{ :voice:ata:spa3102.jpg?300|SPA3102}}

If you use a SIP trunk provider that requires 10 digits, modify the Dialplan in the Line1 (or Line2) settings by inserting ''<:520>'' to the 7-digit section:

<file>
|<:520>[2-9]xxxxxx|
</file>

:!: In this example, we need ''520'' (our local area code) added to dial 7-digit calls.

<file>
(*xx|[3469]11|0|00|<:520>[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.)
</file>

===== Audio Quality and CODEC =====

For maximum bandwidth savings, use ''g.729a''.  Otherwise, choose (the default) ''g.711u'' (uncompressed) for best audio quality.  It's roughly 24Kbps vs. 92Kbps.

:!: Be sure to set the ''RTP Packet Size'' to ''0.020'' on the SIP tab.

===== Paging =====

In our limited experience, paging amplifiers are usually connected to an FXO port of a PBX.  **The SPA3102 includes an FXO port**.

==== Overview ====

  - Configure a SIP Trunk and Outbound Route in FreePBX
  - Configure the SPA3102
  - Determine "Line-In-Use Voltage" of the FXO port and adjust it to match
    - Otherwise inbound calls in will result in a busy signal (SIP response 503 "Service Unavailable")



===== Enable the Web Interface on WAN =====

{{ :voice:ata:spa3102_connections.jpg?300|SPA3102 Connections}}

Whereas the **WAN interface is used to connect to the SIP trunk provider**, the **web management of the SPA3102 is only available on the LAN interface** of the unit.  If your SPA3102 is completely behind another firewall, you will find it more convenient to enable the web management on the WAN interface.

:!: Do **not** make the web interface accessible if your WAN interface is internet-accessible.

The default settings will leave the SPA3102 in an un-managable state if you only connect the WAN port to your internal network...a common configuration.  One would have to connect a portable PC to the LAN interface to administer the unit.

These steps will enable the web interface on the WAN port:
 
  - Plug in an analog phone or 'butt set' into the Phone port
  - Dial ''****'' (four asterisks) for the (audible) main menu
  - Dial ''110#'' for the IP submenu
  - Dial ''7932#'' then
  - Dial ''1#'' to confirm
