Many thanks for sharing the great project.

There is a small error in your docu. Instead of

docker run --name issabel \
-p 25:25 -p 82:80 -p 465:465 -p 2122:2122 -p 5038:5038 \
-p 5060:5060/tcp -p 5060:5060/udp -p 5061:5061/tcp -p 5061:5061/udp \
-p 8001:8001 -p 8003:8003 -p 8088:8088 -p 8089:8089 \
-p 9900:9900/tcp -p 9900:9900/udp -p 10000-10100:10000-10100/tcp -p 10000-10100:10000-10100/udp \
-v issabel-etc:/etc -v issabel-www:/var/www \

-v issabel-home:/home -v /etc/resolv.conf:/etc/resolv.conf:ro \
--cap-add=NET_ADMIN --restart=always -d technoexpress/Issabel-PBX

you need

docker run --name issabel \
-p 25:25 -p 82:80 -p 465:465 -p 2122:2122 -p 5038:5038 \
-p 5060:5060/tcp -p 5060:5060/udp -p 5061:5061/tcp -p 5061:5061/udp \
-p 8001:8001 -p 8003:8003 -p 8088:8088 -p 8089:8089 \
-p 9900:9900/tcp -p 9900:9900/udp -p 10000-10100:10000-10100/tcp -p 10000-10100:10000-10100/udp \
-v issabel-etc:/etc -v issabel-www:/var/www \
-v issabel-log:/var/log -v issabel-lib:/var/lib \
-v issabel-home:/home -v /etc/resolv.conf:/etc/resolv.conf:ro \
--cap-add=NET_ADMIN --restart=always -d technoexpress/issabel-pbx

with uppercase repository name at least I get an error.
