I have successfully planned and migrated a Theatre in nottingham to a VoIP telephone system, I reconfigured 3 Mediatrix ATAs to keep the original telephone wiring for 60 analogue telephone, and in the offices I reconfigured Polycom IP phones to enable advances features such as call control and CIT/TAPI, I also configured there call center for the booking office to take calls in queues and to integrate with there EPR systems for automatic screen popping and selected data entry.
