Subject: Avoid trying to pickup a parked extension before the park operation is completed.
X-Git-Tag: 1.4.35-rc1~9
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=20c9dd4aef85d5d069edcd69a4fc8d5dc7f641d7;p=thirdparty%2Fasterisk.git

Avoid trying to pickup a parked extension before the park operation is completed.

A crash could occur if the extension is picked up while the parking extension is
being announced. Testing pu->notquiteyet while searching for a parked extension
resolves this crash.
