Hi, I got a small question.
Suppose I connect the PSTN port of the Sipura to a CO in a PABX.
Is it possible to forward VoIP calls to the PSTN port so the PABX gets the call and delivers it to the operator extension?

It should work with a hotline cutover DP for the VoIP to PSTN functionality. However, hotline cutover means you give up the ability to hop on via VoIP - it takes any dialled number and routes it to a predefined number on the pbx. Here's how the VoIP caller DP should look:

(<:111@gw0>) where 111 is the operator extension on your PBX.

Thanks for your reply, humba3.
Your idea seems OK to me, but I don't understand what do I lose by implementing it.
Isn't it possible to just forward the VoIP call so the phone port rings on the PBX and the preattendant of the PBX is heard, asking the caller to dial an extension or wait for the operator to answer their call?
(I think this can be done with a PAP2 device, can this be done with the SPA3000?)
Thanks again!

That's what my solution does.

However, some people get an SPA3k, then call their PSTN number from their cellphone, and then dial out again via VoIP. If you now forward all the calls to your PBX, you won't be able to dial out again via the SPA3k's VoIP line (but of course you could program your PBX to offer dialout functionality (assuming your PBX supports that feature).

Thanks again for your reply, humba3.

Please tell me if I'm wrong.
With this DP, when a VoIP call is received the SPA picks up the extension port of the PBX that is connected to the PSTN port, and dials 111 which supposedly is the operator extension.

If that's true, then it is not what I need. To simplify things lets forget about the PBX and change the question to:

I want to connect a standard phone to the Sipura and have it ring when a VoIP call is received, and be able to answer it from this phone. Is it possible?

TIA

But that's something totally different from your first post???? Of course you can do that, it's one of the basic functions of an SPA3k (and any ATA).. but it has nothing to do whatsoever with a PBX.

No, that's not different. I am just not mentioning the PBX in the last post

I will explain a bit more:
Now what I have is the PBX connected to the standard PSTN line. When someone calls, the PBX gets the call at the first ring and says "Thanks for calling, please enter the extension # or wait for the operator", and the user can wait for the operator or dial an extension.
I want exactly the same but instead of connecting the PBX to the PSTN line, connect it to the SPA3000 and answer the VoIP calls in the same way.
Is it possible?
Hope it is clear now

You can't do that.. yes you could call in and yes, you could dial a number and would be connected to that number (via voip) - but there's no way to get the autoattendant.

Understood, I think I should go for a PAP2 then...

Thanks for your help, humba3!!!

[humba3]

I'd be very surprised to hear that the PAP2 has an autoattendant that does more than the one in the SPA3k (there's one.. it allows you to get and set basic system parameters like the system's IP address - and it can only be called from a phone connected to the FXS port) The PAP2 is a dual FXS port ATA box after all.. you call in, and an analog phone answers.
