Our management has been very lenient with mobile phone issuance to our staff and now we are suffering from sudden increase in telephone bills. There are so many unauthorized calls made by most staff and now, we wanted to immediately implement a procedure for all going calls. Aside from this, we would also want to do some further analysis and evaluation on our telecommunication invoices to be able to help us cut down the cost. I'm heading this project and I am really eager to present any effective solution as soon as possible. I'd like to know your common practices at work and let me see if I could also apply those to our firm. Thanks in advance.
