Why do most cable companies install carrier grade VoIP telephony?
Conducting your own site survey allows you to verify the findings from the pre-
installation checklist and to work with your company to determine the time required to
perform the work, which may save you time in the long run.
Carrier grade VoIP telephony is provided over a network that meets CableLab®'s
PacketCable™, and DOCSIS® 1.1 or 2.0 standards at a minimum, which helps to ensure
security system compatibility.
Prior to connecting the EMTA, always test the radio frequency (RF) signal coming into the
building to ensure it meets the minimum signal strength standards.
CableCARDs are used to decrypt a channel lineup and allow the individual decrypted
channels to be reordered and configured to suit the needs of the customer.

How does the technician verify voice services?
As the lines are ported over, the support team tests each number by placing a call. Once
each call is received, a return call is made to verify that the number can send and receive
a call.
The technician should verify how many telephone lines are being installed; the associated
telephone numbers for those lines with the customer; and that the work order matches
this information. Prior to installation, the support team should be contacted to confirm
the telephone lines are ready to be ported.
Create the problem statement by using contextual clues from the customer, asking
meaningful questions, and utilize the customer and your own local team to fill in any
informational gaps there may be.
Once the business class voice services have been installed, make sure each and every line
is verified by testing inbound and outbound calls using the support team or an
automated installation service.
