andy Posted February 6, 2017 Report Share Posted February 6, 2017 Our Vodia PBX worked fine until a couple of days ago. For some unknown reason all Snom phones can't contact the PBX any more (Snom message: Network failure). All of our softphones are working fine. The Snom phones are registered and can be called by the PBX (incoming calls), but not the other way around (outgoing calls). There have been no updates or changes to the network infrastructure, there is no firewall involved. We checked the traffic with wireshark and found this line: <Server IP> to <Snom IP> SIP 547 Status: 401 Authentication Required The Snom phones then CANCEL the sip request. Could this be the cause of the "network failure" and what setting is involved? Quote Link to comment Share on other sites More sharing options...
