We've released a callblasting package for Asterisk @ <a href="http://www.callblast.org" rel="ugc">www.callblast.org</a>. &nbsp;You could use a script like this along with Text-&gt;Speech software on an asterisk box to query your database and place calls like this.
</div>


<div>
If you have some experience with Asterisk Dialplan and Manager APIs you can do it easily. &nbsp;first create an dialplan in your asterisk extensions.conf which should look like this.<br />
<br />
[your_mssg]<br />
exten =&gt; mssg,1,Background(your_ema<wbr />il_is_reco<wbr />rding)<br />
exten =&gt; mssg,2,SayAlpha(${EMAIL_VA<wbr />R})<br />
exten =&gt; mssg,3,Background(your_pho<wbr />ne_recordi<wbr />ng)<br />
exten =&gt; mssg,4,SayNumber(${PHONE_V<wbr />AR})<br />
<br />
<br />
and in you web application. after establishing a connection to Asterisk Manager Interface. get the $number_to_call , $email and $phone variables form you DB. and issue an AMI command with following parameters<br />
<br />
Action =&gt; Originate,<br />
Channel &nbsp;=&gt; SIP/$number_to_call ,<br />
Exten &nbsp; &nbsp;=&gt; mssg,<br />
Context &nbsp;=&gt; your_mssg,<br />
Priority =&gt; 1,<br />
Variable =&gt; EMAIL_VAR=$email|PHONE_VAR<wbr />=$phone<br />
<br />
you have done.

<div>
Using Asterisk Can a different voice message be sent to different users?<br />
<br />
eg.<br />
Hi John, we like Scott's idea on Plan 43211<br />
and<br />
Hi Chris, we would like you to call us and let us know your thoughts on Plan 87136<br />
<br />
Is there a website where I can see Asterisk being used in real-time? I would like to make a call to myself.

If I have a certain status for a user record in the SQL Server database, I would like to make an automated web-based VoIP phone call to the user "your email address is X and your phone is Y ... etc".  If the user is not there, leave a voice message.   How can this be done?  Is there a software or software component that can do this already?

Automated VoIP Phone Calls

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).

Voice Over IP

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.

IP Telephony

Microsoft SQL Server is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.SQL Server is available in multiple versions, typically identified by release year, and versions are subdivided into editions to distinguish between product functionality.
