I am following the instructions from this website:
It uses an OBI-110 and a Raspberry Pi with Asterisk/FreePBX to create a nuisance call blocker. I have followed the instructions and even reimaged the Raspberry Pi several times but 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:
(Yes I know the password is the generic password for now)
Near the end you will see the lines:
== Using SIP RTP TOS bits 184
== Using SIP RTP CoS mark 5
– 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 talked to OBI and they insist that the problem is my setup in Asterisk. 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.
Also, I have tried the setup with FreePBX 2.xx and FreePBX 12, with all modules updated.
Any help would be great. If someone has created a better tutorial for this setup, I would love to hear about it too.
Thanks for any help.
