Help with VoIP over WiFi on Android

JMOZ — Wed, 25 Nov 2009 12:31:28 -0800

I am looking for (recent) experiences with Android options for VoIP over WiFi to deal with places where I have a WiFi signal, but no 3G/voice signal. I'm looking for solutions for two situations: (1) In one of my labs at work, there is plentiful WiFi coverage, but no cell/data signal. I'd like to be able to make outgoing calls, and I'd also prefer if I could receive incoming calls. (2) For international travel, it would be nice to have a way of making calls at least where WiFi is available. The phone in question in a Motorola Droid (on Verizon), and I have Google Voice (and an account), though I haven't yet used it for much. I've seen SIPDroid, though I'm confused at the relationship between SIPDroid, PBXes, and the SIP provider. This confusion is compounded by the recent acquisition of Gizmo5 by Google.

As I mentioned above, I would like a solution for my lab where I can send/receive calls in my lab and also a solution (I'd imagine likely the same solution) that will allow me to place calls when traveling internationally. I realize this will only be an option where WiFi is available, but that's certainly better than nothing.

Does anyone have any suggestions? Firsthand experiences are especially preferred; the info I've found via google all seems slightly vague. If you have a good solution, specific directions would be especially appreciated. Although I prefer free solutions, low cost solutions are also perfectly acceptable, especially for the international travel portion of things.

Many thanks in advance!

Mobile phone with dual SIM, wifi and SIP protocol support

fifigyuri — Fri, 02 Oct 2009 15:00:24 -0800

Do you know mobile producers which provide dual SIM mobiles with wifi supporting SIP protocol? I pendle between two countries, so decreasing my communication bills with a piece of convenience is welcome. Under convenience I mean having one instrument for talking, instead of several ones or one, where I change SIM cards. My vision is to have a mobile which can have two SIM cards, has the ability to access network through wifi.. so when I get home it can automatically identify that it sees a familiar network, it connects and puts me to VOIP provider through SIP. No need to change cards, and at home it is possible to call for less.

The mobile operators does not have the interest to provide offers for such machines, but I found some quite interesting producers: http://dual-com.sk/, http://www.dualsimmobileshop.co.uk/wifi-dual-sim-phones-c-25.html?zenid=hjrd6nfucmd61rl484f6kv3cv3 .

It seems there similar things out there. Do you have hints for other ones? Can you recommend good ones? Other things like the camera, 3G support, OS are also interesting, would be good to have wider spectrum to choose from. But the most important is to have 2 SIM support with wifi and have to know SIP protocol..

Something for the 12-week-old to sip?

zardoz — Sun, 14 Jun 2009 04:47:54 -0800

On training a three-month-old on drinking with a straw...firstly, is it even doable? And is (watered down) juice ok for that age? My wife and I have a soon to be three-month-old, and my wife has been breastfeeding exclusively throughout that time--we've used no bottles, no formula, no breast pump.

We've read recently--from a few independent sources, I might add--that it's a good idea to teach an infant to drink from a straw rather from a sippy cup. We have something similar to this. We'd like to leapfrog over both sippy cups and bottles and have the kid drink with a straw, getting him off the wife's nipple. Not rushing things, but if it's possible we'll at least try it. Personally, I'd like it because then I'd be able to feed the kid myself.

What we've done so far, in the past two weeks or so, is tried to train him to suck some barley tea (for babies). It takes him a while, but he does eventually suck up and swallow in a way; half of it just spills on his bib but he does seem to be improving with this.

SO, here are my questions. Are we being naively optimistic about his ability to drink with a straw at this age? Should we just wait? I suspect he'll be more excited about sweeter drinks. Is (watered down?) fruit juice ok for him at three months? Or some other kind of drink? Formula is ok?

MeFi parents, tell me your straw training stories!

What conference bridge software/system can do this?

torpark — Thu, 26 Mar 2009 20:20:57 -0800

What conference bridge software/system can do this? I would like to find a conference bridge software I can run that is linux based, allows people to call in via VOIP/SIP and landline/mobile, PIN code access to conference rooms, and dialout/dailthrough access so they can call out.

Adding virtual guest participants to a physical meetup

jeffmacintyre — Fri, 13 Mar 2009 09:04:28 -0800

Best way to add virtual guests to a physical meetup? No, I'm not looking for a simple conf calling solution here; angling for something better and more leading edge.

I'm wondering whether there is some apt web app, videoconference or SIP solution for easily adding virtual guests to a physical meetup?

We don't have a location yet so it's still possible that we could get the technical infrastructure in place to make this happen, between phone lines, wifi, VOIP/SIP, etc. Surely this has been solved before by someone far more intrepid than myself.

Business Class VOIP termination

clarkie666 — Tue, 22 Apr 2008 15:24:43 -0800

Can anyone recommend business class VOIP termination that is not a fully hosted solution by the terminating company? So I am pretty new to this area but boy have I learned a lot in the last month. Our small business (50 users, 3 sites) was previously going with a fully hosted VOIP solution but following a full cost analysis the price difference between this and hosting our own was huge which is leading us down the Switchvox route.

We are planning on initially maintaining our 7 inbound analog lines for origination, however the missing link is VOIP termination to the PSTN for our outbound calls. Unfortunately it is difficult to evaluate VOIP service providers since the heavyweight ones provide their own hosted VOIP solutions (and don't seem to offer wholesale termination without using their hardware) and the wholesale providers range from fly-by-nights to what I am sure are reliable companies - but it is hard to tell the difference. Posts to VOIP forums are peppered with sales reps giving glowing recommendations of their own companies.

Can anyone recommend one? How much influence does the service provider have on overall quality and is it possible to buy termination over a private network? Bonus if you are working with a Switchvox or Astrisk system. Bonus bonus for reliable international calling.

Thanks much!

A nest of voipers

VOIP providers in the UK. It's about time for another UK VOIP thread.

I am looking for a SIP (i.e. not skype) VOIP provider that is pay as you go for home use. Making local UK calls to PSTN numbers will be the main use. We have cheap international calls via the landline.

We have a SIP phone.

Vonage, who people have previously recommended, seem to be a bit unsteady at the moment regarding the prospect of continuing to trade.

So does anyone have any experience with other VOIP providers in the UK?

I need help finding a new IM client, please.

omair — Thu, 08 Dec 2005 10:33:28 -0800

I need help finding a new IM client, please. At work, the standard is to use Windows Messenger (version 5.1) because it has the capability to do SIP Communications Service (using TLS to connect). This functionality is not there (I can't see it) in the up-to-date version of Messenger from Microsoft (version 7.5).

But, I also need Messenger 7.5 because it has the new feature of being able connect to my .NET passport account using HTTP (because I can't connect to .NET Messenger from working using normal IM connections or through the HTTP proxy). This newest version of Messenger is the only one that I can find that will connect to MSN.

The proxy at work allows AIM connections, so any AIM client works fine (the standard AOL issued one, or Trillian, or whatever).

Here is the problem: I can't have both .NET Messenger 7.5 and Windows Messenger 5.1 on the computer at the same time. The new Messenger will not install if the old one is present. I cannot use Trillian for my IM needs because Trillian can't connect to .NET messenger over HTTP, and it cannot connect to the SIP Communications Service at all.

Is there any client out there that can do all three things: 1) Connect to AIM, 2) Connect to SIP Communications Service (using TLS), and 3) Connect to .NET Messenger using HTTP? If there is no such thing, then a client that has only the first two functions is fine, as I can probably install the newest version of MSN Messenger to do the third, and have two IM clients running.
