Tips: Cost reduction

Cell phone vs. TU extension

When to use your business mobile phone, when (if possible) to call from the TU extension?

Conversations with the business mobile phone abroad

With the exception of the USA, Canada, Australia and New Zealand, it is generally the case abroad that incoming calls are about half cheaper than active calls. Due to this large difference, it is recommended - if feasible - that employees who are abroad are primarily called from the TU.
