[asterisk-dev] New feature

[John Lange]

Even though this feature would seem to be relatively straight forward to
implement, my guess is it will never happen in Asterisk for the simple
reason that it would require bastardizing the chan_sip code to make it
work.

chan_sip seems like a very poor place to put device specific code.

On the other hand, if there was a way to modify chan_sip so that it
could hand-off these kinds of strange requests to some other code it
might be a useful feature to add.

Perhaps some other developer could comment on this further?
