[asterisk-dev] Zap channel loses DSP after channel moving

[Edwin Groothuis]

Greetings,

I have found an interesting issue where a call loses its DSP after
the channel has been moved:

A call gets setup from a call-file towards a Zap channel on a PRI:

    -- Attempting call on Zap/g4/0409227633 for 0409227633 at barnet-callback:1 (Retry 1)
    -- Requested transfer capability: 0x00 - SPEECH
    -- Moving call from channel 95 to channel 112

So somewhere on the move it loses its DSP. "zap show channel"
confirms this:

Channel: 95
Owner: <None>
Real: <None>
DSP: yes

Channel: 112
Owner: Zap/4:112-1
Real: Zap/4:112-1
DSP: no

The original Mantis bug is at http://bugs.digium.com/view.php?id=11917,
the last note (entered 03-04-08 06:36) gives the current status.

I am not sure how to fix this: I tried re-assigning in
pri_fixup_principle() to move the DSP field to the new channel but
that didn't work.
