My rant (and certainly not directed at you (Telefonix) or any other forum user, but to GS yes) -
My take is that regardless of what type of file, or where derived, if the device accepted it and those tones worked for some period, then there should be no reason that they should quit working sometime later.
GS has had ample time to work this issue, test all the scenarios to include what file types, formats and file sizes should work while rejecting the rest programmatically or, like in other cases, the phone takes the tone but it fails to work from the get go and never works.
As it stands, if it seemingly works, you have no reason to think that it won’t going forward (at least not until recently).
Many have begged for a different or added set of GS supplied ringtones for years. This is nothing new; yet GS has not favored us with same.
This thread goes back to May 20th; yet here we are today ( a couple of days shy of 6 months) still looking for answers (in all the wrong places?) and only wanting something that we can feel good about offering to our clients knowing that it will work and not cause us undue/unwarranted/unwanted service calls for issues that we can’t fix.
I have quit deploying the GRP and have moved on to to something else in the meantime. I will await a true fix before installing more and I will continue to deal with those already installed hoping that a fix will be forthcoming soon.
