ostel.co sip service is down
Judging from your munin graph, the root partition is full
Is the project still alive ? Its bug tracker (ostel) is closed.
Offline from here too.
This service is much valuable, although I understood it is not amongst Guardian's project anymore.
Any way to re-enable it ? Would be much appreciated.
If no action is possible from here, would it be possible to forward the bug-report to the actual maintainer ?
