----------------------------------

    Resolution: Workaround Available

This functionality can be accomplished in 11 and above using pre-dial handlers[1]. They should not suffer the same problem.

>             Project: Asterisk
>          Issue Type: Bug
>          Components: Applications/app_dial
>    Affects Versions: 1.8.4
>            Reporter: Vadim Mikhnevych
>            Severity: Minor
>
> Upon calling Dial() with U() parameter, called channel seems to stay in app_dial_gosub_virtual_context , because if called person tries to make a transfer (using codes from features.conf , like #1), and is asked to enter number to transfer call to, only one digit is read, as Asterisk immediately looks for the extension to transfer to in app_dial_gosub_virtual_context.
> If there is no U() used in Dial(), transfer works great.
> So, it's impossible for called party to perform attended or blind transfer in this way, because transfer number can't be entered.
> Dialplan for called subroutine:
> [SET_MOH_VOLUME]
> exten => s,1,GotoIf($["${ARG1}" = ""]?not_moh)
> same => n,Set(CHANNEL(musicclass)=${ARG1})
> same => n(not_moh),Set(VOLUME(TX)=${ARG2})
> same => n,Set(VOLUME(RX)=${ARG3})
> same => n,Return
> Asterisk log:
