Here in Ireland its easier to get "wholesale" call termination prices
with the local telcos if you are dealing with SS7 rather than PRI ISDN.
I think its just because the different technologies are how they view
carriers vs. end-users. It doesn't make sense I know because both SS7
and PRI ISDN come from the same switches.

Can someone give me an example of the cost/feature differences between SS& and

much differently would Asterisk configurations be using SS7 vs. PRI?
Thanks
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.
I am not sure what _I_ would do with the CPC information in my case. It may
be good to know where the call came from so that I can setup more cost
effective route in the future but Caller ID (number) seems good enough to
start. So simply converting the SS7 message to a PRI should be good enough.
If I can pass the caller ID information down to the Voip Subscribers that
would be the only reason I need it.
What do _you_ use the CPC information for?
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).
It is the primary way to interconnect to the ILEC (at least Qwest in the
Northwest). The cost of lines controlled by SS7 is only a fraction of PRIs
from Qwest or other providers.
Markku Korpi's driver is not cheap for sure
Yes but it is certainly less money than most hardware solutions I have seen
out there. (Markku hasn't gotten back to me yet from my first email to him
so I am not even sure whether I will be able to get it if I want it)
Best of luck! When you are finished I you might want lots of
money for
your non-opensource SS7 software too! :)
I am not a greedy person but of course I wouldn't mind lots of money (That
is why I am in business). Asterisk has helped us a ton and at very little
cost. We might be able to give back depending on what it will end up
costing. There is always a consulting / support income possibility even if
it is open sourced. (I don't want to talk like it is done before I even
start though)
