Having a Skype (video/voice) in public in Paris

There are two logical answers - one a lot cheaper than the other:

• office hire. If this is an important call, you could look at hiring office space for a half a day. There are various companies that offer this service. A very quick search showed me companies like instantoffices.com - http://www.instantoffices.com/en/fr/office-space/paris?for=0-3&size=1
• headset. I have successfully used this option in busy locations, such as internet cafes. A good headset will pick up your voice and very little else, and only you will be able to hear the person speaking to you

Both will need wifi, but that should be relatively straightforward.

Sharedesk lists a couple options for hourly coworking within your budget of under 15 euro/hour, depending on the time.

You can try heading for a hostel to use their chillout room. You might need to ask for the WiFi password, and if you fell guilty about the fact that you're not a guest there you can always buy something at the hostel bar, if any. Moreover some hostels do not have passwords protected WiFi networks.

One example hostel where this might work is the St Christopher Canal's Inn in the Crimée neighborhood. For starters they have a bar you can use without being a hotel guest, hence you can purchase something and ask for the WiFi password. They also have a calm chillout room where you can sit and talk.

Whichever option you should chose, remember to bring along a serious headset, and avoid using the inbuilt laptop microphone since that will pick up all the ambient noises.

If the weather is good, one of the outside free options might do for you, depending on how good your computer/phone is in connecting. I remember sitting near the east end of Notre Dame cathedral in a relatively quiet garden. Use a headset with a good mike and you can talk in very low tones.

Besides, I have seen many a person do skype type calls in internet cafes, again using a headset. Bring your own headset as I doubt the internet cafes do supply them. Paris internet cafes are not cheap, at least I have never found a cheap one when I was still traveling without my own computer and used wifi.
