News, Notes, & Miscellaneous Fun Stuff

  • CC video update - Yes, they are actually coming! Thanks to quentusrex for x-coding
  • I'm slowly getting caught up on changelog. Here are some new items:
    • minor improvement to mod_voicemail
    • add threaded-system-exec param and fsctl (set it to false to use fork) (r:910f5364)
    • change -hp to -rp, add -lp and -np, no priority flags means auto which will do -rp if you have > 1 cpu (r:c1dd008b)
    • Add application flag zombie_exec so registered applications can apply to be executed on channels that are already hungup, like the inline exec this is only limited to a small family of apps that do not use the channel for audio. (r:637a5ed8)
    • make app to turn on new zombie exec instead of always doing it (r:3a2f8183) (API=uuid_zombie_exec, app=set_zombie_exec)
    • fs_cli: implement configurable prompt, input, and output coloring (We'll let TC give us the lowdown)
      • In .fs_cli_conf, set:
      • prompt-color => blue
      • input-text-color => red
      • output-text-color => yellow
    • add _continue_ value for fifo orbit exten that just means exit back to the next dp instruction (r:4d6ee827)
    • add ivr_menu_terminator variable you can set to none or the dtmf chars you want to terminate input (r:0a3e5d2f)

Featured Presentation

Suggestions For Future Meetings & Future To Dos

  • Math: Sofia internals
  • Eliot Gable: mod_ha_cluster
    • What is mod_ha_cluster?
      • In short: N+X (N Masters + X slaves) HA replacement for "Pacemaker + Corosync managed FS"
    • What is planned for mod_ha_cluster?
      • In short: manage interfaces, IPs, firewall rules, master/slave status; eventually, share registrations and call states without shared DB and do 'sofia recover' on failover
    • When will it be available?
      • In short: Master/slave, interface, IPs, and firewall management within the next couple of months (if I have the amount of time available that I expect to have)
    • For additional details, or if you would like to beta test, be on the call
  • Jeff Lenk: developing for FS in Windows environment
