> Given the following dialplan:
> {noformat}
> [default]
> exten = 123456,1,NoOp(CHANNEL function demo)
> same = n,Set(CHANNEL(userfield)=something)
> same = n,NoOp(exten: ${CHANNEL(exten)})
> same = n,NoOp(context: ${CHANNEL(context)})
> same = n,NoOp(userfield: ${CHANNEL(userfield)})
> same = n,NoOp(channame: ${CHANNEL(channame)})
> same = n,Hangup
> {noformat}
> When I call 123456
> Then I see in the console:
> {noformat}
> Executing [123456 at default:1] NoOp("PJSIP/caller-00000001", "CHANNEL function demo")
> Executing [123456 at default:2] Set("PJSIP/caller-00000001", "CHANNEL(userfield)=something")
> WARNING[0001][C-00000001]: func_channel.c:463 func_channel_read: Unknown or unavailable item requested: 'exten'
> Executing [123456 at default:3] NoOp("PJSIP/caller-00000001", "exten: ")

> WARNING[0001][C-00000001]: func_channel.c:463 func_channel_read: Unknown or unavailable item requested: 'channame'
> Executing [123456 at default:6] NoOp("PJSIP/caller-00000001", "channame: ")
> {noformat}
> Expected: I don't see warnings, and I can see the value of exten, context, userfield and channame.
