STATUS SIP TRUNK

[ToniGarcia]

Hi, I have made a SIP Trunk against another external PBX and it marks it green, but I don't really know if it is established, although it sets up an incorrect IP it is always green, how can I know that the trunk is established?

To be able to transfer calls to another PBX that does not have a bridge, is the way with SIP Trunk?



thank you

Hi there.
If your settings for "Type of authentication " are set IP-based, it will always be green as it is not checked for authentication.

Thanks, it's correct, I have IP authentication configured, but I need to know somehow that the trunk is up.

If it's not registration "Register/account base" you won't know. Only using logs of the system/network captures.

thanks,
Where can I see the logs commented by system/network?

in activity log and events I have not seen anything

Couple of things you could do:
- in the Dashboard > Troubleshooting section > Connections, you can see if your Provider IP is there and connected
- to use 3CX System logs, you will need to get the support info file in verbose and then you binlog viewer tool.
- run networking Capture, use Wireshark and then filter with the IP of your provider

great, thank you very much for your help

You are welcome.
Have a nice day

sorry, I have v18, I don't See Troubleshooting section / connections

 

[OlegR_3CX]

Oh, i see, is because you are on V18 and I was referring to V20.
So in V18, you have a terminal (PBX Status section), where you can also run the commands.
If you open it, you can use the command: netstat -tun
or other netstat command

 

[ToniGarcia]

Thanks for the information, I have other links working that are not sip trunk, they are bridge and they do not appear with the netstat -tun and netstat command.

 

[OlegR_3CX]

Oh yeah, it's because there's no state/status for UDP connections and the trunk uses UDP.
Use the other options.

 

[ToniGarcia]

OK thanks.

 

[ToniGarcia]

I have downloaded the 3CXPhoneSystem.bldef log and there is no trace of the TRUNK that I created, I only have wireshark left, but I see that it is too cumbersome to only see the status of the trunk and possible errors.

 

[OlegR_3CX]

If the System was verbose, you could use IP to filter with. Wireshark should show you also if the system if sending data and if the other end reply to it.

 

[ToniGarcia]

Okay, I also think that it should be easier to see this information, let's see if when we update to v20 we have clearer information.

 

[OlegR_3CX]

It will be no difference there the moment you use IP-based trunks.
