 ===== 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:

 For maximum bandwidth savings, use ''g.729a''.  Otherwise, choose (the default) ''g.711u'' (uncompressed) for best audio quality.  It's roughly 24Kbps vs. 92Kbps.
-Also, be sure to set the ''RTP Packet Size'' to ''0.020'' on the SIP tab.

-===== Web Interface on WAN =====
+==== 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 =====

+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.
-Normally, the web interface of the SPA3102 is only available on the LAN interface of the unit, even though the units are usually completely behind another firewall.
+:!: Do **not** make the web interface accessible if your WAN interface is internet-accessible.
-Since the WAN interface is used to connect to the SIP trunk provider, the default settings will leave the SPA3102 in an un-managable state...you would have to connect a portable PC to the LAN interface to administer the unit.
+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:
