The article states that IDPC + SGCP became MGCP (which is supported in *, 
correct?).   I don't know if the world's telecommunications regulators have 
addressed MGCP or SIP interconnections yet, so SS7-IMT will be a reasonable 
choice for connecting to the highly regulated PSTN for quite some time (maybe 
until VoIP dominates PSTN).  

Letting the guy that owns the bigger network always helps in the 
certification process :-)

Thanks for all the replies.  I got some off-list in support.  There's lots to 
noodle through here.
