I set up an Elastix PBX with a VoicePulse.com SIP trunk. Elastix is Asterisk and free. The GUI looks pretty good and I was able to get everything set up in a couple of hours. I have never set up a PBX in my life.

I had an elastix box for a while and after watching a few vulnerabilities go unpatched and getting hacked twice I gave up on Elastix... http://www.elastix.org/en/component/kunena/116-security/6078.... Switched to PBX in a Flash and while its more secure, the user interface is clunky and requires you to use a number of custom closed-source scripts to keep everything up to date...

I use the native SIP functionality in Android 2.3, and it works well. Sipdroid is available in the market if you're looking for a solution for earlier Android phones. There are literally hundreds of providers to choose from. callwithus.com seems to have really good termination rates ( http://www.callwithus.com/showrates ) and I use them for calling mobiles in Europe. They don't support inbound calls, but there are ot…

Whoa. Callwithus seems to help a LOT here. Still, like ~all~ answers, we're talking audio only, but yeah, this would help me a lot.

Thanks!

Thanks a lot. Used that link, signed up. Got 0.5 EUR (which is a lot, with these rates. Nice!) and tried a first call. Call was excellent on my side, very bad on the other side. "GTalk's better", "Lots of noise" and it got dropped after roughly 1:30 with both parties not hearing anything. I hang up after 20 more seconds and verified the results via GTalk with the other side. First impression: Generous credit on sign…

Did you try calling the test bot? It's just an echo service that we've provided with which user can test if the connectivity is ok between his machine and vox.io server (and if mic settings are ok). Also, you can try to call yourself (I mean your mobile/fixed number), just to check the quality of audio. We try to route the calls through high quality gateways but sometimes a call is still not good.

Ah, so you're affiliated? :)

No, first thing I tried was a 'real world test', calling a German mobile number from here (Tel Aviv, Israel).

Yes, I am. I thought it was obvious enough without a disclaimer ;). I don't know who simonb is, though, and I wasn't planning to even answer your question since you want video calls and we only have video for vox.io to vox.io calls. There's no support for 3g video calls.

will give you a comparative of a lot of VoIP provider, which usually can provide you a DID.

For the video side, what I'm doing with more or less luck is to use the Jingle protocol, used by Google Talk, on Asterisk. This one is doing a gateway. So depending on what is available on each side, the video functionalities are rather video SIP to video SIP, video SIP to Jingle or Jingle to Jingle.

I'll post soon an article on my blog to explain how to do so.
