Vo802.11 Telephone System Cost Justification in the Workplace
The following paragraphs describe how Vo802.11 saves enterprises money. Vo802.11 makes managers
more efficient and thus saves their employers money.
Cost Savings from Immediately Answering Calls from Long-Distance Customers When customers or
suppliers are statewide or national in scope, their long-distance telephone bills are significant. By
immediately answering incoming calls from customers and suppliers, companies save the cost of
returning those long-distance calls later. The following calculations illustrate this cost saving:
l Average dollar cost per long-distance call = $2.50
l The number of long-distance calls per day per supervisor not made due to the use of SpectraLink
Wireless Telephones = 2
l The number of supervisors = 6
l The number of workdays per year = 300
l Dollar savings = $2.50 × 2 × 6 × 300 = $9,000 per year
Savings in Interoffice Telephony: A Case Study of Amber-Waves WISP Vo802.11 AmberWaves is a
WISP in northwest Iowa. One of their clients has 3 offices with 35 employees, which are linked by an
802.11 network. The greatest distance between the offices is 19 miles. Calls between the offices are long
distance, which retails at 10 cents per minute in this rural community. Data circuits are not inexpensive
here either.
AmberWaves has equipped customers with 802.11 wireless bridges to connect the LANs in the three
offices. By adding a voice over Internet Protocol (VoIP) gateway, the company was able to route their
interoffice phone traffic onto the 802.11 network between the three offices. This meant all traffic that
previously went over the Public Switched Telephone Network (PSTN) was diverted to their internal
802.11 network, saving them money on both local phone bills (no need for a large number of lines to
serve the 35 employees) as well as eliminating their interoffice long-distance expenses.
This wireless network enables the firm to be its own internal data and voice service provider. The use of
Vo802.11 frees the firm from local and long-distance telephone bills (see Figure 8-1). The end users
report that the quality of service (QoS) on the network is better than the frame relay circuit they previously
used.[4]
Figure 8-1: Using Vo802.11 in interoffice telephony saves on both local and longdistance phone bills.
It is useful to apply Figure 8-1 to Table 8-4 to see how this company has saved money on their
telecommunications expenses in bypassing local telephone service providers.
