IX Workplace and ISPs

[kgoth]

We are using IX workplace for remote workers. Is going great, only downside it seems one of the ISPs that a lot of users use for home internet is not working. So on cellular data the app works perfectly. When connecting to their WIFI that the ISP is CenturyLink it works fine! For me on the other hand I use Spectrum for my ISP. The app opens and will sometimes connect and if it does I can try to make a call but no audio. Or it won't even make the call.


Is there certain ports that the ISP themselves have turned off that won't allow this connection?

Any thoughts will be appreciated!

Probably they have some kind of application layer gateway to detect and block voice.

I assume you don't use encryption?

Derfloh thanks for the response.

To my knowledge no we don't use TLS if that's what you mean. I was kind of thinking the same thing about Spectrum blocking something. I am trying to get with their National tech support about going over things with them and see what we can do. Will update thread once I can find something out!

Over the internet it's strongly recommended to only use TLS. It's not too hard to be honest. I can help.

That was my next goal once I have accomplished being able to use this app on outside wifi connections. After this Spectrum discussion I will be putting my efforts into setting up TLS for sure! Thanks!!

The good thing with using TLS is, that no one will be able to look into the packets to adjust things or to use the packet content to block something. They will just see them as encrypted packets.

The can interpret it as SIP by the used port 5061. If that's the case you can change the ports as well.

Good to know! Thanks for that information.
