怀疑是SIP scanner造成的:

命令行打开以下命令试试看:
xConfiguration SIP ListenPort: Off
xConfiguration SIP Profile 1 Outbound: On
SymptomGhost call. It appears that the codec is calling itself automatically. Placing a codec on a public IP will cause calls from SIP scanners. These scanners (e.g. SipVicious) are used to detect possibilities for exploiting PSTN trunks. Solution is upgrade to TC6.2.0 or later and execute the following configurations:
xConfiguration SIP ListenPort: Off
xConfiguration SIP Profile 1 Outbound: On
ConditionThe system is on public IP or reachable from the outside and not protected well enough. This makes it possible to initiate SIP calls over direct IP.
WorkaroundMake sure the system is well protected and that it is placed in DMZ if you need to have it on public IP. It is possible to only allow calls from the VCS by disabling the listenport on 5060/5061, but then SIP outbound needs to be enabled so that the VCS can reach the endpoint.
xConfiguration SIP ListenPort: Off
xConfiguration SIP Profile 1 Outbound: On
