Dear All,
Baytalkitec is the company that Mr. Bala represents and US company is Concerto softwares which was known as Davox.
Baytalkitec have developed their own software based on contactpro4.2 and have demonstrated the same for domestic use in Goa Telecom Deppt.However I will recommend the clients like minerva telelinks and trionline to ask them about how well this baytalkitec provides the after sales service in case of some failures in the software and how often does this happens and how badly it makes their work suffer.
regards
