this issue is likely that the (saved) config will not fit in nvram w/o
compression, not that it will not be displayed (which is always
uncompressed).

assuming there are no special commands to display voip stuffs, it should
work.

i expect there are likely things that ought to be filtered for security
or reduce diffs from config goop that changes automatically (such as ntp
drift or uptime).  Those would be welcome patches.
