Subject: [Megaco] polarity line reversal on seizure

Hi,

I'm trying to understand what the benefits are of applying polarity reversal on seizure over simply 
requesting offhook, ringing, and ringback when attempting termination. Is polarity reversal on 
seizure implemented for symmetry with line reversal on answer? What are the drawbacks to supporting 
line reversal on answer without line reversal on seizure?
Thanks,

-Brent
