Hi,
When I am on my cell phone in Ireland and my friend is on his cell phone in the UK it is expensive to call each other. To get around this I would like to do the following:

My SIP account has a SIP-IN landline number in the UK. If my UK friend dials this number it connects to my SPA3000's VOIP1 port. At the same time I want to be able to call my SPA3000's FXO port and for the SPA3000 to answer both my call and my friends call and connect the two calls together so we can talk.

Is this possible?

Cheers,

Irwin.

I am not quite sure what you are asking. The SPA 3000 can be setup so that an incoming PSTN call can be tranferred to voip or vice versa,

[Irwin]

Thanks for your reply. I will try to clarify:

I want an incoming PSTN call and an incoming VOIP call to be connected together automatically by the SPA 3000.

Hmm.. that would be a VoIP1 -> VoIP2 -> PSTN call.. I don't see this listed as a supported scenario.. on top of that you'd actually not go that route but VoIP1 -> <- VoIP2 <- PSTN.. even some large PBXes have problem with such a scenario and you can only go one way (so when you want to transfer a call, you have to press the transfer button, then dial the number you want to transfer the call to, rather than e.g. receiving another call, and press the transfer button to connect your existing call to the call in ringing state).

Irwin,

As you do your research by reading through the previous threads here, you will find that not only is this not a supported scenario in the SPA3000, but that there are several workarounds that other members have developed. This includes one thread that was last addressed just four hours ago.

If you choose one of these solutions for your own, feel free to post a comment in that thread if you run into trouble implementing the advice you find there.

You can set the 3000 (I think) so that if it sees an incoming call from a particular source it will immediately transfer it to a particular voip number (if from PSTN) or to a particular PSTN number if from voip. Is this what you want?

I can't seem to locate it.. would you mind sharing the url please?

That would be VoIP1 -> VoIP2 -> PSTN.. while that obviously does work, it's likely to be more expensive (calling a cellphone from a landline generally is more expensive than calling a landline from a cellphone) and he said he wants to come from both sides, not pass through the device from one side. You are correct insofar that the passthrough solution is feasible without any workarounds.. it's one scenario the device was built for.

The thread I was referring to is this one. There are several more at the end of a Search for "strap", which I tend to mention each time someone opens a new thread on this topic.

[humba3]

Ahh.. that's what's meant by strap.. I immediately thought of guns. But either way, strapping isn't the way to go here.. it's still a one way deal and he wants to come in from both sides.

I see no way in getting the two sided entry to ever work.. even the one scenario where the two voip accounts are interconnected, this is initiated by one side and it goes through the device from one end to the other.

The only way the scenario would work is if once he calls the FXO port and the device picks up, he can somehow get the device to do a blind transfer from the call in ringing state on voip1 to the active call on the FXO port. And afaik the only thing you can do when the device picks up your FXO call is authenticate, then dial out again.. not control an call on the VoIP 1 account. Even when you look at large business PBX's, you can initiate a transfer if the person doing the transfer is part on both calls. Other than that the only way is to have a CTI app listening to certain DTMF commands and interconnect calls programmatically. But since there's no CTI for the SPA3000, unless Sipura adds support for such a transfer scenario I don't see it happening.

You're right. Irwin is looking for a MeetMe conference service inside his SPA3000. That's not in its bag of tricks.
