I have a request from a customer and was wondering if anyone has set up something similiar. The customer is a call centre. They want to provide the facility to agents, that when they answer a call and if this call is a complaint, they agent can press a key on their phone to keep a record of a complaint call. They then want the facility on CMS to be able to report how many complaint calls a particular agent has taken. Any suggestions or advice would be much appreciated.
