I just installed the FreePBX Distro BETA-3.211.63-1 (which is running FreePBX 2.11.0.0beta1.3) with Asterisk 11.1 and I noticed that when my extensions are set to use the Default ring time they ring indefinitely. I looked into this issue and discovered that the default ring time is being saved to /etc/asterisk/extensions_additional.conf as "RINGTIMER", however all of the extensions reference "RINGTIMER_DEFAULT" which isn't set to anything. I have attached a patch, which seems to resolve this issue by naming the global variable RINGTIMER_DEFAULT instead of RINGTIMER.
