Let's hope this fixes it for good and doesn't introduce new problems.

FS3245 move pid var in redhat/centos init file to /var/run/freeswitch/freeswitch.pid, as it gets instaleld to do so

Remove pri_destroycall() in on_hangup() and
use pri_hangup() instead of the deprecated pri_release().

NOTE: The original patch used PRI_CAUSE_NORMAL_CIRCUIT_CONGESTION for the cause
      code, which (without pri_enable_hangup_fix() enabled) emits a RELEASE COMPLETE
      message. This version of the patch uses PRI_CAUSE_NORMAL_CLEARING (-1). (stkn)

Additionally, use ftdm_set_state() instead of ftdm_set_state_locked() because the channel
is already locked. (stkn)

FS-3276 --resolve please attach the diff next time, do not paste it into the comment.  It ruins the formatting.  Also I changed the patch so the variable names refelect what is being harvested namely sip_bye_content_type and sip_bye_payload

default timer to run slower and increase as needed, Run the timer at 20ms by default and drop down as needed unless you set 1m-timer=true which was previous default

FS-3277 --resolve There are actually really only 2 places where it needs the real hostname, the hostname command and the header on the events.  I changed everything to the switchname because there were some more sql stmts etc in the core.

ftmod_libpri: ignore missing call_data in on_hangup() and use the call handle passed in the pevent structure (still needs more love...)

add bridged timestamp and hangup_complete_with_xml=true to add xml_cdr to the body of hangup_complete events

mod_crd_sqlite entry limit and sqlite segfaults on triggers

mod_callcenter: Apparently, it by design that only 1 of the 2 leg can continue the dialplan.  So member are always A leg and agent are B leg.  If you want to continue after hangup a call for the agent like in uuid standby mode, use the transfer_after_bridge feature. Sample example usage is on the mod_callcenter wiki page.
