>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Channels/chan_local
>    Affects Versions: 1.8.15.0

> Marked as regression, because this still works in 1.6.2.x.
> Consider the following dialplan:
> {noformat}
> [default]
> exten => s,1,Dial(Local/fax at default)
> exten => fax,1,NoOp()
> ;     same => n,Answer()
> ;     same => n,Playback(silence/1)
>      same => n,ReceiveFAX(/tmp/abc.tiff)
>      same => n,Hangup()
> {noformat}
> with the following sip.conf:
> {noformat}
> [general]
> t38pt_udptl=yes
> {noformat}
> If you attempt to send a fax to extension 's', you get this:
> {noformat}
> [Aug 14 17:21:34] ERROR[28450]: res_fax.c:1071 set_fax_t38_caps: channel 'Local/fax at default-962f;2' is in an unsupported T.38 negotiation state, cannot continue.
> {noformat}
> If you send a fax to 'fax' directly, things work as expected.
> A patch that fixes the behaviour is attached, and reviewboard item will be created.
> (If we enable the Playback, we get a warning: "file.c: Unexpected control subclass '24'"
> but that doesn't alter the rest of the behaviour.)
> Kind regards,
