Hi,
We have a C20 Cisco Tandberg which has a recent strange behavior. Basically, it calls himself every ten seconds when on without visio. During a visio, the C20 disconnects every five minutes.
Do you have any ideas of what is happening ?
Thanks.
Fabrice.

For the "calls itself" issue - that's likely a misconfiguration somewhere in your infrastructure on on your endpoint that is allowing a SIP or H.323 probe to come through and appear as a call. Have a look at
https://community.cisco.com/t5/telepresence-and-video/unknown-incoming-calls-on-codecs-sx20-c40/td-p/2730561 for some ways to prevent this.
For your "drop every 5 minutes" issue - that is almost always a firewall timeout issue. You will need to investigate your firewall settings.
It's also worth mentioning that the C20 is an end of support endpoint. The last date of support was 31 August 2018. You should consider replacing it with something more modern and supportable.
