Increasing ring time on HTC 8925 Tilt

[LittleBreezes]

Hi all, I am using an unlocked AT & T 8925 Tilt (WM Pro 6.1) on T Mobile. I would like to increase the number of rings or time it rings before the call is sent to voicemail or forwarded. I was under the impression that this was a function of the netowrk so I called T Mobile and they told me that this was a change I needed to do on the handset. I have looked all over in settings but haven't found anything that pertains to this. Can anyone tell me how to increase the time it rings before being sent to voicemail or forwarded?

hmm you might want to call them up again and see if you can get a different person.

This is a network setting so you should contact T-Mobile again.
On your Tilt you can control on the "Automatic pickup", in other words after how many rings the phone will pickup automatically.

Cheers!

Thanks, I was pretty sure of that before I called TMo the first time. I will try calling them again and see what happens.
