    Hello,

    I've had the SBC working, now it's stopped and I have no idea why. There has been some work done on the 3CX server by a third party but they're insisting it couldn't have had an issue.

    I've tried the SBC for Windows and Raspberry Pi without any luck.

    The output I'm seeing on windows is:
    And the RPi one shows a similar output.

    My config file is:
    Code:
    [Log]
    Type=file	# cout, cerr, file, syslog
    File=C:\ProgramData\3CXSBC\Logs\3cxsbc.log
    Level=ERR	# NONE", "EMERG", "ALERT", "CRIT", "ERR", "WARNING", "NOTICE", "INFO", "DEBUG", "STACK", "ERR", "VERBOSE"
    [Bridge/123456]
    Name="SBC"
    Password="IOBRkULwz17MN"
    ID=123456
    SecurityMode=0
    #LocalSipAddr=0.0.0.0
    #LocalSipPort=5060				# local SIP (UDP/TCP) address (def: 5060)
    TunnelAddr=1.2.3.4
    PbxSipPort=5060
    TunnelPort=5090
    PbxSipIP=10.201.18.10
    [General]
    PrintStatsInterval=30
    ReconnectInterval=30
    
    (obviously I've changed the public IPs)

    The error log shows:

    The one thing which stands out to me is the 169.254.180.133 IP address, where would this be coming from?

    Thank you

    Go to 3CX SBC config file on the program data.

    And delete # to localip adress of 3CX SBC and set your local ip of SBC. Restart service.

    I'm filled with mixed emotions. On one hand I'm so happy this solved the problem. On the other hand I'm so annoyed it was so simple!!!!

    Is this because the computer running the SBC has a couple of NICs in it?

    Thank you for saving my sanity.
