Hi,
I have 13 year experience with CTI (computer telephony integration), further I have lot of experience with Asterisk, FreePBX and FreePBX dialplan. It will be an easy task for me.
I am ready, if you want to start right now. If you select me, I will provide complete activity and changes logs, for your future reference.
Note: you have to provide server ip, root password for ssh access, and web admin access
Regards
