Gizmo on AT&T 3G

[lax2tlv]

Has anyone been able to set up Gizmo VOIP on AT&T's 3G? I have tried everything and cannot get it to connect. Gizmo and VoipStunet works fine on WiFi; also, VoipStunt CONNECTS on 3G but doesn't work properly. Is AT&T blocking Gizmo and if so is there any way around it? I've considered Fring but the lack of DTMF support renders it useless with Grand Central... and the Gizmo5 Midlet seems like a dirty attempt to play into the hands of the service providers (i.e.- AT&T)...

Any advice??

[EDIT] BTW-using Schap's 4.3

Sounds crazy, I know you've already tried it, but....

Proxy is off if using wap.cingular?

ISP setup is isp.cingluar to get a real ip (not 10.whatever...)

Ive used the wap.cingular for everything but that and have had no problems
(slingbox, orb, etc.)

I only use wap.cingular. With no prxy obviously.

I, too, have been able to use everything else with no problem.... but cannot figure this one out...

What softphone do you use? Here is some softphone to try, I test them all on my hermes. They are all working.

Exactly what symptoms / behavior occurs when you try to dial VOIP over AT&T's data connection? Does it connect? What's the error message? Can you NOT send / receive audio?

This seems like a common issue. So far I haven't found anything decisive in the forums to indicate anyone is successfully using VOIP with AT&T's data network (Edge or 3G) on the Hermes. That is, when using the integrated phone dialer.

Even when the same VOIP configuration works with WiFi, for whatever reason it fails on AT&T's network. When I had the Wizard I did have this working with a Faria ROM. But since switching to the Hermes I've had no success. I don't really think it has anything to do with AT&T blocking any services, ports, traffic. I'm almost certain of it since VOIP will work on AT&T's network if you use a 3rd part VOIP application like SJPhone or XLite.

Tested all 3 of them and, while they can make calls, none of them ring/receive incoming calls...weird...

So nothing at all??
