Update to 1.2.9.1 which addresses a security vulnerability in the IAX2
channel driver (chan_iax2). The vulnerability affects all users with
IAX2 clients that might be compromised or used by a malicious user, and
can lead to denial of service attacks and random Asterisk server crashes
via a relatively trivial exploit.
