prevent call forward loops

I have my Vonage line set to simultaneously ring at home and on my cell phone. It works great except for one problem. When I go to call home from my cell phone, Vonage tries to also ring my cell phone...the same one I'm calling from. This results in my cell line going straight to voicemail, and the phone in the house doesn't even ring.

It would be nice if Vonage would detect these forward loops and make it not happen. Or even better, allow us to selectively forward individual phone numbers.

how do you set it up to ring both? Is that the hunt group feature?

It is the "SumulRing" feature. See the call forwarding feature menu for this.

I need it to forward to my cell phone, and this bug is very, very annoying. It would be simple, really. All they need to do is check if the incoming caller ID is the same as the simultaneous ring number.. if so, don't ring the assigned number.

If it's so simple, why don't you engineer the solution, code it - and send it off to Vonage?

I love it when non-technical people suggest these "simple" solutions - without any clue about the underlying technology.

For reference, I am a technical person. You want the solution?

if( caller_id == call_forward_number ) {
// Don't forward to the call_forward number as to prevent loops
}
else {
// Do the call forward.
}

Not foolproof as it relies on caller ID, which can be spoofed, or not provided if they use an anonymizing function (no call back, etc), etc. As it is not foolproof, perhaps have it an option in our Vonage control panel. Caller ID information can never be fully trusted unless it is coming from a toll-free number, and even then caution must be used.

I would gladly engineer such a solution if I had the source code and hardware infrastructure to test it.

I've gotting bitten by this one, too. I just chalked it up to my being an idiot! Wink

Maybe Vonage can save me from myself...
