Doubts regarding VoIP system

@Himura1 said in Doubts regarding VoIP system:
If an IP PBX like Asterisk/Freepbx is used along with IP Phones, would internal calls still be charged? I'm confused on this part since I would still be assigning the DID numbers from the PRI lines to the extensions.
No, even on normal legacy systems internal calls are not charged. The old Siemens system there is probably not a true PBX, as normally internal calls can't be seen by the telco.
With FreePBX or any VoIP PBX, the internal calls are internal only, no way for any outside entity to even know that they are happening. They are definitely free.

But you do not need to dial the DID to call them internally. And if you do, you'd make the PBX connect you directly, not call out over the PRI just to receive the call over the same PRI.

Thanks @scottalanmiller and @Breffni-Potter for the clarification.
@scottalanmiller Could Indian telcos use any specific tool/technology to monitor internal calls? Or is it something impossible?
Current PABX is Siemens Hipath 3550. Is this a proper one?

It's impossible. No different from them not being able to charge you for talking to people in the office in person. It's not part of the phone system, it doesn't leave the building, it's totally private and owned by you.

You sure that that is a PBX and not a gateway?

No PBX will have the issue that you describe, something is very wrong if your telco has any means of seeing your calls, even on a 50 year old PBX. Either they have access into your facilities that they should not have, or your calls are leaving the building without being handled by your PBX, or you have the device shown and you have no PBX.

I haven't visited the client site yet scott, all this information is gathered through phone conversation with the prospect.
I will be visiting them tomorrow. I would need to identify if its an PBX in the first place! -

A PBX would make what is happening impossible (unless it was completely screwed up and not set to work as a PBX) so pretty safe to assume that the actual switching is being handled by the telco.

What would be the function of gateway? How is it different from a PBX?

Different in every way. A PBX is a switch and does not imply a connection to the outside world. A PBX is how you switch calls between extensions or trunks. You can put in a PBX and put extensions on desks and people can call each other. Same as having an Ethernet switch and computers on desks and people can send files to each other. Neither requires an outside line.
A gateway like this is for converting VoIP on one side to a telco line on the other - they should not exist in the modern world because things like POTS and PRI "should" have all been replaced decades ago. But many companies keep these old, expensive vestiges. A gateway takes internal calls and hands them directly to the phone company, just like your Internet gateway does.
So...
PBX: No way for the telco to see internal calls.
Gateway: No such thing as internal calls. -
@scottalanmiller Siemens HiPath 3550 is a telephone system, as they call it, and basically it is PBX.
The only way telco could charge for internal calls would be to rent PBX to customer and charge it as part of service. -

Only inbound or external calls should be visible.
@scottalanmiller it is a PBX, a really old one.

The device that I linked was not a PBX. If you search on that name, several totally different items come up.
-
If it's a hosted/rented system, the vendor will have access to see inside the system and can therefore charge based on internal calls.
-
If the users are calling a DID instead of an extension, then of course the provider sees it and charges for it.
Sounds like the system is either misconfigured or the users were incorrectly instructed.
