CCSS Warnings help

Hello

I have two servers, a primary and secondary (Asterisk 11.14.2). Today after a reboot of the primary I started seeing the following messages on sip to sip calls. On rebooting the secondary I dont see these messages. Can they safely be ignored, why would they appear on one server and not the other?

Check your config on /etc/asterisk/ccss.conf

General Overview

A new feature for Asterisk 1.8 is Call Completion Supplementary Services.

What is CCSS?

Call Completion Supplementary Services (often abbreviated “CCSS” or simply “CC”) allow for a caller to let Asterisk automatically alert him when a called party has become available, given that a previous call to that party failed for some reason. The two services offered are Call Completion on Busy Subscriber (CCBS) and Call Completion on No Response (CCNR).
