[Observium] Adding a SNOM 320 VoIP Telefon failed

Hello,

i tried to add a SNOM 320 VoIP Telephone. I saw that Observium has an include for snom devices. As a first test a bare snmp request from cli with v1 succeded, with v2 i got no response.

But Observium does not discover the device with v1. DNS / host name service is working.

I have read in the web that SNOM SNMP support is awful. They have their own mib, a request for "system" does not give an answer from cli.

Does anybody have SNOM Devices monitored in Observium and if so, what could be the error that the device could not discovered and added?

thx, ecaroh
