[asterisk-users] Sine Dialer, GNU dialer, VICIDial and others slightly OT?

[John Millican]

Hello All,
I have a requirement to setup a predictive dialer for a customers call center. 
I am asking for pros and cons of the different dialers available for 
Asterisk.  If you are going to send marketing material send it to my  e-mail 
directly please and not to the list.  I was hoping to get the opinions of any 
one using any of these dialers and what they liked and didn't like, ease of 
integration with asterisk, stability, and such.   
Thank You for any help
