Usefulness of Mobile call back?
Technically this is a great feature but I struggled to find a practical situation where I would want to use this.
Imagine this scenario where I am at a public hotspot, take out my E61, log in and initiate a call back, the phone ring, I got connected and talk...sounds right but then, if I have net access already I might as well use the SIP function on my E61 (which register very well with Voxalot, thank you) and make that call using just one leg of the VSP. Or if I am at home with ready Internet access, I can't think of why I would use a call back. Of course not all Internet phone has SIP client, granted, but pretty soon they will, I would hazard a guess. So frankly once you have Internet access, there is little reason to use call back. What would really be useful is if there is a way to initiate that call back using a normal call back technique of a a PSTN number that you call, it drop the line and then call you back (using the web callback technique of course), except in this case you can chose your VSP and the rate etc. now that will be really really useful. |

As for Web CallBack, of course its useful if you have a WAP phone without SIP (plenty still around!). I also use it to initiate international calls when I'm at work (on the web) and I let my sister use it to make international calls from home on her PSTN line. Keep up the good work VoXaLot!

Actually mobile callback is quite useful in its current form for me. I have a prepaid mobile phone, so my calls are expensive (think EUR 0,35 per minute).
It's cheaper for me to use the (simple) browser in my phone and use mobile callback to pay for both legs of the call with the much cheaper VSP rates (EUR 0,15 to mobile and EUR 0,01 to land line, a total of EUR 0,16 per minute if I call a land line from my mobile, plus a cent or so for accessing the mobile callback web page). |

Well don't get me wrong, I think the facility is useful, but has limited application in its current format, by the addition of a way to access without Internet access, it will be much more useful and will find application in many more ways.
If I am at home now or at a hotspot then I can just use the E61 SIP directly, eliminating one leg of the VSP charge and less voice delay and technical complications. Even without the E61 VoIP ATA are quite cheap these days, even advanced one like the PAP2T cost just USD55 (EUR43) to buy which gives you 2 FXS port to play with, so if you have direct access to Internet already, there is little need to get callback. I am sure there are situations, like the one described here, that it proves useful, but it is rare. The most useful time is when you can't have Internet and yet can get called back and still use VoIP on your mobile, now that would be brilliant and would open up its use far more |

One more thought
Just thought about a possible way to use my 3102 with call back. If one of the leg is the PSTN line on my 3102, and it is set to call my mobile immediately on incoming then I got that local call side covered, then just wait for the other side to connect.
The problem I have is that the system does not wait long enough (as it needs to dial out) and gets into all manner of "funnies" Anyone have any thoughts? |

I can think of a number of areas where Webcallback is very useful. 1). The user is at a location where dialup is the only option. 2). No ATA or VoIP equipment. 3). One-Way satellite. 4). Limited bandwidth. |

On one mobile phone ... I press Go to, 8. After a few seconds the Voxalot phonelist appears. I scroll down to Eurotunnel and select it. About twenty seconds later, the other mobile phone rings. I'm in a call queue for quite a while, but not getting neurotic about it. Eventually I change the time of the booked crossing home to the UK. The 13 minute call costs me 18 pence. The wap/gprs trigger is included in a contract tariff, or about half a penny if I exceed the allowance. . Last edited by andy; 03-01-2007 at 12:59 PM. |

I've got iBurst on the road in the car running it and a router off my car battery; I could just as easily add VoIP if I wanted.
The only problem is that iBurst for me has always had far too much latency for VoIP. So a VoIP on the motorway is very possible... provided there is some form of wireless broadband available that is suitable. |
