This doesn't meant that all premium services are expensive. Systems are being disrupted at such a rapid pace you can often find incredible services – like a free virtual fax machine – completely free.
- Hangouts is not reliable for phone calls. They have a great dial out feature, but I've been on a couple calls where the call connection kept dropping out. It was embarrassing and made me lool sloppy.
- Calling someone's cell, or having them call you, often creates a coordination problem. What if you or they are a couple minutes late? You then have to call again, text them, email, etc to adjust coordination. Using a conference line eliminates this problem completely.
I've also found that a call is often more effective than trying to use a video conference, especially if it's a one-off conversation or if it's more of a prospecting call. Phone calls are low friction and globally compatible: everyone has a phone and can use it from anywhere. Video conferencing software still frequently fails and can make the start of a conversation awkward and jerky while you both try to get your conference software working.
