Hi Dipanjan,
 
Thanks a lot for your response.
 
your comments are really great help to me for further processing on this issue.
 
However I was wondering if, is there any open-source alternative for this solution??
 
Best Regards,

Easiest way is you can buy one simple ATA (analog terminal adapter). E.g. Cisco ATA or D-Link SIP voice terminal adapter. Connect your phone to this adapter with normer phone cable (RJ-11) other end, device to Asterisk server/PC would be an ethernet. the ATA shall take care of understanding analog events coming from the phone and converting them to standard SIP message and vice-cersa. thanks, Dipanjan
