Creating Junk Call Blocker with Obi110 and Asterisk returning Error 503

[sgarret3]

I am following the instructions from this website:

http://www.liquidstate.net/blocking-silent-and-nuisance-calls-with-an-obi110-raspbx-asterisk-pbx/

It uses an OBI-110 and a Raspberry Pi with Asterisk/FreePBX to create a nuisance call blocker.I always end up with the a situation where calling my home just rings (for the caller) and the home phone never actually rings.

I have posted a dump of the "rasp*CLI>" resulting when an outside call is placed and posted that to:

http://pastebin.ca/2865843

Near the end you will see the lines:

-- Called SIP/813
-- Got SIP response 503 "Service Unavailable" back from 192.168.0.72:5060
-- SIP/813-00000007 is circuit-busy
== Everyone is busy/congested at this time (1:0/1/0)

I have followed the directions for both the OBI and Asterisk, and even reset the OBI and reimaged the Raspberry Pi a couple times, but I always end up in the same place.

I did find out that if I call my house when the "LateNight" condition is met, I will hear the "Press One to Continue" recording twice in a row, but when I press "1" I get a fast busy signal.

I feel like I have something wrong in the Asterisk "Trunk" or "Outbound" call configuration, or maybe something that changed in the latest Obi110 firmware update that is making my setup different then the tutorial, but I can't figure it out.

Thanks for any help.

Have solved this problem. The tutorial had an error that needs to be corrected for OBI110 setup:

OBI110:
   VOICE SERVICE
      SP1 SERVICE
         Set X_InboundCallRoute: ph (Not LI as in tutorial)
