Voicemail on Tmobile, any way to increase??

[Yas786]

Sorry for the vague title but basically i have my divert to voicemail setup that if i dont answer the phone it automatically goes to voicemail. But with my phone it rings for about 5 secs before going to my voicemail and id like to increase the time delay.

Now is there any way i can increase it to say 20secs before going to voicemail??. I have the SE W810i and i cant see any settings related to voicemail ie timings or anything like that. So would i have to ring tmobile to find out??

TIA

Arg you can't increase it more than 25?

Problem is most people wont even bother waiting for you to pick it up after 25 secs, even 25 secs is a bit long imho. But seems like it works perfectly fine.
