Our friend David over at Penny Tone has an article out on call Quality.
Many Wireless Internet Service Providers (WISPs), especially newer startups, struggle with nat issues and having enough public Ip addresses to go around. Invariably, you start running into double nat issues pretty quickly. Then you get the dreaded gamer call:
Many times they don’t know why they are even calling. They just know the magic box is saying this is bad. This is related to how many layers of nat between your edge and them. Many times you are natting at the edge, then you are natting at the customer router. If you have multiple customers behind the same nat at the edge this compounds it even more.
So what is the fix? Give the customer public addresses. But IPv4 is hard to get! I didn’t say IPV4 I said public addresses. IPv6 is a public address. When given the choice between v4 and v6 most modern streaming and gaming platforms will prefer v6. Xbox has supported a protocol called Teredo for a long time. You can learn all about Teredo in this PDF. Basically, it is a tunnel in which the Xbox speaks ipv6 over the tunnel. The ISP does not have to support v6, which does away with the above-mentioned nat issues.
Great! I don’t have to worry about IPv6, Microsoft has it taken care of for me. There are two problems with this statement. Problem number one. There are more companies out there than Microsoft. Sony Playstation Online, Apple gaming, and Steam are just a few. Second, you have overhead of tunnels. In the world of who can pull the joystick quicker, milliseconds count. You don’t want them wasted in tunnel overhead. Plus, v6 is beneficial for other service such as Netflix.
Any other service that runs into port issues behind nat can be solved with Ipv6, This can be voip, cameras, and other type services. This is providing the product or service supports v6 addresses.
So what is an ISP to do?
Awhile back I put together a resource guide for ISPs. You can find it at https://blog.j2sw.com/networking/ipv6/ipv6-planning-and-implementation-resources-for-the-xisp/
Recently I sat down and did a podcast with Daniel White of Atheral (https://atheral.co/). We talked about how WISPS can use VOIP to prevent overbuilding, Unified communications, and some of the forms and procedures for getting started with VOIP.
If you want to contact Atheral about their products you can do so at the following:
Lately, I have had folks asking about telephone service and who I recommend. Many questions stem from people working from home and cell phones have weak signals or battery life is an issue after a day of calls.
We have relationships with two different companies
if you need voice or unified communications check both of these out. Tell them Justin sent you.

Why should a WISP care about VoIP?
- Government Funded Competition – Offering VoIP with your awesome broadband experience protects your ISP from being overbuilt by government-funded competitors or enables you to apply for government funding to expand your coverage area.
- Customer Stickiness – Customers that purchase value-added services are more likely to stay customers, especially when they are satisfied with those services.
- High Margin – While phone service in the home may be declining, VoIP is growing by leaps and bounds in the business community with the VoIP industry seeing ~21% annual growth through 2025. All those added users equal high margin for you – the average VoIP reseller sees margins in the 40%-65% range.
