3CX 7.1 Issue
Posted by CyberData Administrator, Last modified by CyberData Administrator on 03 February 2015 02:56 PM

I upgraded my 3CX PBX server to 7.1 and now my Rev B CyberData VoIP IP Speaker and My VoIP Paging Amplifier do not stay registered with the server.

There is a 3CX version 7.1 registration / timing bug. To correct this problem, complete the following steps:

  1. Log into the 3CX PBX system, and select SETTINGS -> ADVANCED -> CUSTOM PARAMETERS.
  2. Scroll down to select the NONCEEXPIRATION parameter.
  3. Change the NONCEEXPIRATION value from 1 to 2 and save the changes.

Note: There are pictures of the 3CX PBX pages and parameters at the end of the document at this link.
