That's an oxymoron. If you are doing SIP over internet, by definition, it
*cannot* ever possibly be reliable. Neither you nor provider control the
path in between. Quite possibly, the definition of word reliable in the
lemonade-stand kinda way is not the same 'reliable' in the
telco-five-nines kinda way.

I will admit that getting SIP handoff directly into the carrier's SBC is
no worse (possible issues with faxing aside) than proper PRI. However, 
you'll notice that carriers who provide such interface still charge on the 
basis of concurrent channels.
