Conclusions1.
Telephony providers will need to use blends of Last Mile Networks
in order to deliver voice services on a National basis
for all types of customers.
Conclusions2.
Providers will be faced with several challenges when using blends of technology.
It is important to use Asterisk to its full potential to combat the challenges and offer customers
the highest quality with committed uptime.
