I've been having a LOT of problems with Gizmo recently, and despite a number of postings requesting for assistance on their forums that yielded no help whatsoever, I have since given up on Gizmo and moved on to Voipbuster.

Why? Because I make all outgoing calls to PSTN numbers using the built-in Internet Call application, so setting up the voipbuster account in Accounts makes it that much simpler to run. Gizmo is a fancy front-end to a generic SIP service, and I really can't be bothered to deal with the quirky service and lack of customer support any more.

I've effectively written off the 18 bucks I have remaining in Gizmo as a bad investment. I might go back to using them, if they ever get things working right. I'm very disinclined to believe that the problem lies with my network because I am able to make good quality calls using voipbuster and not via the Gizmo service set up in my SIP Account settings.

8 out of 10 times, the called party doesn't even ring when making a call of any kind (PSTN or PC-to-PC), and in the case of the remaining 2 times, the called party's phone only starts ringing after 30 to 40 seconds of ringing on my end, and the calls are terribly laggy. I have had no such problems with voipbuster so far.

I'm going to put together a simple video demonstrating my experience with both later this evening (my office LAN blocks the SIP ports), and you guys can see why I've given up hope on Gizmo.

My gizmo calls/answers but I don't get any sound in or out. It used to work well, even better than skype.

I suspect that upgrading to rtcomm might have something to do with it. I did try renaming one of the offending codecs but that didn't make a difference.

There is a new version of gizmo as of a day or so ago. It didn't fix my problem. I don't use it much, so will probably wait for an OS upgrade.

Gizmo was known to be having some issues back in late Jan and despite claims that they have had it fixed, many users are still experiencing problems.

I do not have the rtcomm beta installed, and the problems are consistent with Gizmo on my desktop (XP), notebook (Vista), N800 (OS2008 51-3), and Nokia E51 smartphone (Series 60 v3 Feature Pack 1)

The pause and resume trick is something I have to to also; although sometimes it does work without doing it.

I opened a support ticket about it. Maybe you can do the same so Gizmo can see it is not an isolated incident.

Other than that the voice calls to an XP client work without problems.
