This service allows incoming voice calls, as well as internal connections.
The service host is configured via Debian VM, configured through git.hamburg.ccc.de/CCCHH/ansible-infra/.../resources/z9/yate/docker_compose.
We have three SIP providers that route incoming calls to us:
Emergency Numbers are routed to the public emergency numbers through the Fonial SIP line:
Four-digit numbers are routed through EPVPN.
No other outgoing calls are allowed.
We have a number of phones in our rooms:
We can easily add additional extensions/devices, either as SIP phones or as ATAs (for example Granstream).
The most stable way currently to do call routing is by setting aliases or “alternatives” on an extension to all numbers that shall make the extension ring.
