I am trying to create a phone dialer exactly like what you find here: http://www.leads360.com/products/integrated-dialer.aspx  I want to be able to collect all of the information you see in the example link as well.  Call start time, length of call, end time, etc.

I use shell command through VBA with x-lite.

'dial the number
Shell (g_strXLitePath & " -dial=" & txtLeadPhone), vbMinimizedNoFocus
'minimize x-lite
SendKeys "%{ }{n}"

The other option would be to have the server initiate the call....and send the call to a meetme() application upon connection.  You could also make asterisk an auto dialer with using call files.

I preferred not to use the server to initiate the calls, because there was a lot of work involved with using the AMI, or other, in order to control the callflow and recieve/process events.  Since i'm not using asterisk as an auto dialer..it wasn't necessary for me.  My CRM is an ms access .ade application with SQL backend.

There's really a lot of ways to do it...and it all depends on your needs for controlling/reporting call flow, and the programming language you are using.

xuserx2000,
thanks for your response.  Not sure where to start though.  My application is written in ASP with MS SQL backend.  I am pretty good with ASP and VBScript, but not as savy with other programming languages although I can usually figure things out with some guidance and example code.  

I would like to add a Click-to-Dial link to all the phone numbers in my CRM.  Click-to-Dial mode, would instantly connect the agent and begins dialing the prospect, automatically handling the dialing and call disposition. It eould also provide a complete audit history with built-in reporting to aid in client teams management.  I hope this helps you understand what I am looking to do.

Any chance you could guide me into a more specific solution based on this comment?

For an ASP page, you could create a //file: URL ....   to point to x-lite path... with -dial 5555555555
Of course the display of the URL would simply be the phone number, which users click on to execute x-lite with the -dial switch.

You will have to check permissions for launching an executeable from a webpage.....probably add the site to trusted sites and lower security for trusted sites for it to work.

Here is a an executeable file, that you can use serverside to execute a call against the AMI.
This is done in vb.net, so just compile it as an exe, and use it on the site.

USAGE: call.exe -c:{numbertocall} -p:{calleridnumber} -g:{agentgroupname} -t:{tablename} -a:{account} -r:{recordid} -u:"{agentname}"  -ai:{asteriskipaddress} -ap:{managerportnumber} -au:{asteriskmanageruser} -as:{managersecret}


You will notice that some variables are set on this command....these can be useful to reference the exact customer record, or agent information tables...from the dialplan.

variable: callednumber=" & phonenumber & "|groupname=" & groupname & _
        "|tablename=" & tablename & "|record=" & record & "|account=" & account

These will be accessible from the dialplan as channel variables....

${groupname} - group id or name the agent belongs to.
${tablename} - tablename the record was retrieved from.
${account} - account type name or id that the the record belongs to.
${record} - record ID number for the customer record.
${agent} - agent name or ID number.
