The version of Asterisk installed on the remote host may be affected
by a denial of service vulnerability.
According to the version in its SIP banner, the version of Asterisk
running on the remote host is potentially affected by a vulnerability
that could allow a remote attacker to crash the server. The
vulnerability can be triggered by sending large audio packets (if the
internal_timing option is off), or by negotiating a media format with
a sampling rate greater than 32 kHz. Both attacks require that the
dialplan use the Milliwatt application with the 'o' option.
