For me to be on-board with the change, we'd have to apply it to all
channel drives that implement said codecs allow / disallow logic, so
sip.conf, chan_ooh323.conf, gtalk.conf, h323.conf, iax.conf,
jingle.conf.
That way all our documentation / functionality is consistent among
channel drivers.
Yeah... that will never happen.
I assume this is about the codecs option. If so, why couldn't it be
implemented in all the channel drivers. Surely the "codecs list" option
could be a simple wrapper for "disallow all, allow list".
