[ Corrected: verbose won’t work, either ]

I think you will need to use “core show channels concise” to get the full channel name. There are more than four digits in the suffix.

The official 18.4 has a 20 character limit for the simple command:

whereas the concise version has no limit, and is designed for machine use:

or use the latest version, which has a 64 limit:

You can also use tab completion to get the full channel name for the command.

*CLI> core show channel PJSIP/flowroute-00000018
*..detail provided via console, as expected...*

core show channels concise worked!

It also says “concise” is depreciated which I am sure you know.

Thank you very much!

to view command , you can type some and TAB, asterisk will suggest you what to enter next

in your case, command is " core show channel PJSIP/flowroute-0000 "

Is core show channels concise really being deprecated?!? Pity, because it is handy for returning channel details in an easily parseable format. Here is a Python function for creating a list of dicts, each containing the info for one currently existing channel:

    async def get_channels(self) :
        "gets information on all currently-existing channels."
        result = []
        fields = \
            (
                "channel",
                "context",
                "exten",
                "prio",
                "state",
                "appl",
                "data",
                "cid",
                "accountcode",
                "amaflags",
                "duration",
                "bridged_context",
              )
        response = await self.do_command("core show channels concise").split("\012")
        for line in response :
            line = line.split("!")
            if len(line) >= len(fields) :
                result.append(dict(zip(fields, line)))
            #end if
        #end for
        return result
    #end get_channels
