From 0a22a515254856fc8cd0e5fe35be8b2849b44fa4 Mon Sep 17 00:00:00 2001 From: Russell Bryant Date: Fri, 6 Jul 2007 23:01:22 +0000 Subject: [PATCH] If a sip_pvt struct has already registered an extension state callback, remove the old one before adding a new one. If this isn't done, Asterisk will crash.
