Note: Own VoIP telephone system behind Centro Grande

Hello everyone

If someone ever has a project similar to mine, you shouldn’t get the idea of ​​forwarding a large UDP port range (10000-20000) to the PBX (RTP ports), because the Centro-Grande refuses with such great rank, they tacitly give up their service. Smaller ranges (like 60 ports) are fine.

Has anyone had similar experiences? In any case, if I had known that, I would have been spared a lot of troubleshooting…

In what context do you need such a system as a private person?

I can well imagine that this wouldn’t have been a problem with Centro Business.

Why do you need a Ferrari? Because you can 😉 No joking aside, it was an experiment for learning purposes.

It’s clear to me that you can play with it :-) I was just wondering why a “private person” would do that…

But maybe you can experiment further by testing this on an SME Anschluss with Centro Business.

I managed it, just had to split it up into smaller ranges. And whether I’ll ever get to a Centro Business where I can “experiment”…
But there are a few cool extras that a PBX offers, such as follow-me functions, a real voice mail system, “internal” telephony over several floors and mobile with SIP client 🙂

Hello Tobias

I’m very interested in your solution, I’m planning to attach a Rasperry-PI and Astersisk.

How did you manage that, which adapters do you use, generally, what does your solution look like?

There are many reasons why you would want to have your own telephone system. For example, advertising calls annoy me, which is why I currently have the callid blocker, but I would like to be protected beyond that.

So when I make a call, I want to search for the number with my contacts (already happens today), but if it can’t be found, I ask on the internet who the caller is and show them. If it can’t be found, I won’t let the call go through, if the number is reported on Tellows (you can enter telephone terror numbers there, in this forum these numbers are rated from 0=serious to 9=telephone terror.

If swisscom doesn’t manage to protect me despite the star entry, I’ll just do it myself.

Depending on the software’s assessment, I can then play different texts to the caller, such as:

They are a call center and are trying to harass me despite the star entry

or

Even if marketing surveys are allowed to call (legally) despite the star entry, they still annoy me but I know how to protect myself.
