35. Conclusions
1.
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.
36. Conclusions
2.
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.
