[Asterisk-Users] Who would use Asterisk SS7?

[Hemant Kumar]

Yeah am sorry to write the half fact. But I just thought you are familiar
with Zap hardware.

For PSTN you can use Zap Hardware like T/E/400P/100P. Zap driver is also
pretty much stable. I am using the same in a call center and having PD,ACD
and most of the funtionality you have read about CTI Hardware.

Now, if you are really interested in SS7 on *, then talk to www.openss7.com
guys. They have claimed to develope SS7 enabled driver for T/E400P card.
