[asterisk-users] Howto grab back call transfered from SIP phone

[Russell Brown]

Once in a while, someone mis-dials when transfering a call on their Snom
SIP phone (using the Transfer button).

Instead of sending them to, say, 1940; they mistype and enter 194 or 190
or somesuch.  This ends up on the PSTN (for which three digit calls are
valid); not what anyone wanted.

On our old PBX (Network Alchemy Argent Office) there was a dialcode that
grabbed back the last call that went through your extension - very
useful when you realised what you'd done.

Is there any way of programming this in Asterisk?  I've googled to no
avail :-(
