I tried that already, but Asterisk throws the following error:

    -- Executing [h at default:1] Set("SIP/OpenSER-0831a618<ZOMBIE>",
"X-CHAN-NAME=SIP/OpenSER-0831a618") in new stack
[May 17 18:24:32] ERROR[6101]: func_global.c:106 shared_read: Channel
'SIP/OpenSER-0831a618' not found!  Variable 'X-DST-CODEC' will be
blank.

as OpenSER-0831a618 doesn't exist any more. Looks like maybe SHARED()
variables are not inherited by <ZOMBIE> channel?
