Chapter 3. ITSP and Voice Codecs Optimization

This chapter reveals the most important things to consider when connecting voice traffic to FreeSWITCH — what you want to check out in an Internet Telephony Service Provider (ITSP) to get the best resulting quality and more bang for your bucks.

In a fiercely competitive market, many operators are floating different products and offers, targeted to the general public, to companies of a specific size, or to vertical markets.

In this chapter, we will cover:

  • ITSPs – what they do
