hey, see link below, i am using Home Assistant for domotica, i started that thread sometime ago, i update it sometimes, when i find some usefull info to share with other users... i also linked a dropbox with all isapi... BUT, i see you already have the latest firmware 2.2.52 , thats sucks

The firmware i use is a custom one, and you cant downgrade anymore, so ISAPI for alertstream + callsatus doesnt work for you
What works, is that you can send a remote open door with isapi , that wll work...
If you you also want events, like, door opened by user .... , callstatus, you can use that python script, i have that one now running too... another guy is also converting it to a java module....

anwyay, back to SIP

i just created some chan_sip extensions, based on UDP, port 5160 , enabled video, and make sure h264 is selected for video, as for audio only ulaw/alaw
my doorstation = extension 2000
my indoor + some linphone clients are like 2001 , 2002 , 2003 , ....
created a follow me group 2100 with members (2001 , 2002 , 2003 , ....)
from the outdoor i just call 2100 as number setting...
thats all, i use freepbx, no diaplans, no trunks , quite a basic config
but i want to know more about conference, i never setup that, is that an extra free module?
what files do i need to change? how would the code look like, with the extension numbering above?
thnx!
