I like how easy it was to setup my calls using our TeamSpeak server; there were no issues at all! The sound quality through Teamspeak isn't terrible either - but you can do better if your budget allows. If we need an open line when working remotely, then switching over to Skype would be ideal so that everyone has audio available without having dedicated phones/lines for each person. We use Cloud Talk mainly because most people have access to computers while out & about which makes communication easier overall.
