there is no need for an sbc and break the call in two legs and drop my 
cool extensions I have in my softphone.

htable does it very well in this case if you want to store initial 
values and if the device are rfc3261 compliant and look only at the 
tags, you can put what so ever crap there.

The comparison is more like: it's better to have an airplane instead of 
a car to drive on highway because can be done without wearing safety 
belt, which is required only for take off, landing and turbulence :-).

Cheers,
Daniel
