Hello,
I am new as a freelancer but I have been working with different asterisk based software like vicidial, elastix and freepbx for around 9 years. The work I have done includes (but not limited to) installation, maintenance, repairing of calling servers plus some different custom work depending of the customer that I am working with at the time. If you consider I can be of help to your project please do not hesitate to contact me.
Regards,
Franklin
