Operations¶

Operations for running a SIP-DMR portal.

Guide	Description
Scaling	Grow from 2 to 10+ concurrent calls
Troubleshooting	Common failures and fixes

Monitoring¶

Poll regularly from your monitoring host:

curl -sS https://your-portal.example.com/stats
curl -sS https://your-portal.example.com/bridges

Alert on:

Memory > 85%
calls stuck > 0 after expected hangups
Bridge count in docker ps exceeds /bridges length (orphans)

Capacity¶

Tune MAX_ACTIVE_CALLS in exchange .env to match VM size. PBX should play a portal-busy prompt when exchange returns 503.

Match DMR_PORTAL_MAX_ACTIVE_CALLS in phonebook config.php if using Everywhere phonebook.

Deploy hygiene¶

Prefer thin rebuilds for routine exchange/bridge updates
After exchange docker compose up --force-recreate, check for orphan bridge containers
Periodically docker system prune on small disks

FreeSTAR production¶

FreeSTAR Everywhere runs this stack in production with operator-managed allowlists and dedicated hosts. Internal runbooks (exact hostnames, extension lists) are maintained by the core team and are not published in this wiki.
