Unable to make a phonecall

[Guest A.B.]

I have a problem with my blade since a couple of days and hopefully somebody has a solution. I'm not able to make phone-calls via the 3G network anymore. When I call sombody I can only hear myself speaking, amplified, but not the ather party, but they can hear me. Strange thing is, that this doesn't happen when somebody calls me, then there is no problem at all. When I switch off 3G and call using 2G there is no problem. This problem only happens when I use the KPN network (in the Netherlands) or other providers that use the same network. When I try a SIM-card from another provider there is no problem.

This is what I suspect the problem is. KPN recently introduced HD voice (amr-wb) on their network to enhance the voice qualitiy. Only certain phones are able to use this new technology. In theory the blade should support this as well. This technology uses the 3G network and when not available it uses regular gsm. So, difficult problem.... Anyone an idea? I'm still using the original ROM, gen2 phone and never changed anything about the software. I'm willing to try, but don't wanna lose the guarantee in this phase when it's still possible that something is wrong with my phone.

It seems that I'm not the only one with this problem, found at leas one other guy.
