[asterisk-users] Help - call recording being cut short if transferred

[Julian J. M.]

Add /n to you Local dial string, i.e.:

Dial(Local/1234/n)

>From http://www.voip-info.org/wiki/index.php?page=Asterisk+Local+channels :

Adding "/n" at the end of the string will make the Local channel not
do a native transfer (the "n" stands for "n"o release) upon the remote
end answering the line. This is an esoteric, but important feature if
you expect the Local channel to handle calls exactly like a normal
channel. If you do not have the "no release" feature set, then as soon
as the destination (inside of the Local channel) answers the line, the
variables and dial plan will revert back to that of the original call,
and the Local channel will become a zombie and be removed from the
active channels list. This is desirable in some circumstances, but can
result in unexpected dialplan behavior if you are doing fancy things
with variables in your call handling.
