<p class=MsoNormal>Hi Ujjval <br>
<br>
I have had this problem also with malicious hackers attacking my voicemail
boxes and making outbound calls to International destinations (Usually the
Phillipines).<br>
<br>
For the time being - I have disabled all outbound dialing through the Voice
Portal. If my subscribers want a function such as this they can either use one
of two things.<o:p></o:p></p>
<ol start=1 type=1>
<li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;
mso-list:l1 level1 lfo3'>Remote Office<o:p></o:p></li>
<li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;
mso-list:l1 level1 lfo3'>BroadWorks Anywhere.<o:p></o:p></li>
</ol>
<p class=MsoNormal style='margin-bottom:12.0pt'>Also increasing the password
policies for Voice Portal/Voice Mail Passwords does help, No longer do I allow
passwords which are shorter than 5 characters (As most attackers use the
default 0000, 1234, 7890 password combinations). <br>
<br>
I am in Canada and I haven't found anything I can do besides that. <br>
<br>
Thanks<o:p></o:p></p>
