Excludes the P8352 value if the default setting grandstream_speaker_ring_volume is unset. Depends on PR #5522
Before anyone asks, Mandatory just means that the variable must be valid, not that it must be included in every XML download. The phone already has a valid value in its internal settings, so as long as we stay safe from setting it to an empty value or outside of the range of 0-7, we are safe. Excluding it is a valid option, which is also true for all settings labelled Mandatory in the Grandstream templates.
