QUESTION Active Calls and Channels

[Peebs]

Hi All,

I have a weird issue where I'm seeing lots of active calls and channels in use but no one is logged into the system and no actual calls are being made.

FreePBX Statistics
Total active calls
2
Internal calls
0
External calls
0
Total active channels
2
FreePBX Connections
IP Phones Online
0
IP Trunks Online
1
IP Trunk Registrations
1

The calls and channels and randomly going up and down between 0 and 14 active at any one time but sill no internal or external calls are being made.

Core Show channel verbose gives me: *Replaced External IP with XX*
Channel Context Extension Prio State Application Data CallerID Duration Accountcode PeerAccount BridgedTo

I've tried disabling the trunk and doing full reboots of the system, clearing the channels but I just can't figure out what is causing this.

Can anyone help identify what the issue is?

Many Thanks,
Peebs

Since we know nothing about your particular installation, and how you have it configured, it would be simply a guess on our part. But it would appear that you are allowing external connections to your PBX, and "someone" or something is trying to gain access from the WAN side.

This would be a clue:

Executing [801743972598652749@from-sip-external:1] .... "Received incoming SIP connection from unknown peer"
