Who I have the same questioned this topic

One adjustment our current smartphone doesn't have that we found it needed in order for better communication with our office's phone system is the ability to adjust the DTMF tone; so, while researching new smartphones, it is something we are looking for.  This is not listed in the User Guide for the Motorola Droid Razr so I chatted with Verizon and was told that since this is such a new phone, it should be capable of this.  I then emailed Motorola, they replied that the DTMF is not adjustable on this phone.  Have any Droid Razr users found this to be an issue?
