[Asterisk-ss7] My Take on the SS7

[Derek Conniffe]

Hi Michael,


To me the reason I'd really like SS7 over PRI ISDN is that I would 
really like to get the CPC data on incoming calls which PRI ISDN cannot 
do and thats it in total.  Currently the only choice is Markku Korpi's 
commercial SS7 driver.

I think not many people need SS7 - maybe its not big/available in the 
US?  Also normal businesses will get by fine with PRI ISDN (they don't 
want/need the CPC switch data).

Markku Korpi's driver is not cheap for sure

Best of luck!  When you are finished I you might want lots of money for 
your non-opensource SS7 software too! :)
