change incoming call ring length

[Guest jingo_man]

hi

just flashed wm2005 onto the device, getting some reuse out of it. however, on my previous phone i changed the length of time that incoming calls ring for to 30 secs (default is something like 15 secs).

on this device you entered the following to do so:

**61*007**30#

when i enter this onto the c500, using the phone app, it returns "command not supported". i am on t-mobile and think that it is more of a network setting than a phone setting. does anyone know how i can get this changed? ringing their customer services doesnt seem to help either...

thanks,
