Confirmed live: on a box also running Asterisk from this repo,
`docker network connect caddy_net traccar` failed with "failed to bind
host port 0.0.0.0:5038/tcp: address already in use". Asterisk runs with
network_mode: host (services/asterisk.sh), so its AMI (port 5038,
hardcoded in services/sms-inbound.sh) binds directly on the host's
network stack — no Docker NAT involved. Traccar's docker-compose.yml
published the entire 5000-5150 range for device protocols, which
needs Docker to also bind host port 5038 for its own port-forwarding,
directly colliding with Asterisk's AMI on any box running both
services from this repo.
Split the TCP range into 5000-5037 and 5039-5150 to skip that one
port; left UDP as a single 5000-5150 range since AMI is TCP-only.
