YML772 Rev1

NetComm’s V85 VoIP Desktop Phone is a next-generation IP Phone that provides a cost-

effective solution for home and SOHO users who want to use their broadband Internet 

connections to make telephone calls. The V85 supports the popular SIP protocol allowing 

for ease of installation with VoIP service providers. By using state-of-the-art DSP (Digital 

Signal Processing) technology, the V85 delivers outstanding voice quality that is comparable 

to the PSTN (normal phone) voice quality.
With the built-in LCD display, the user can easily configure and view phone settings and

phone book entries. Besides providing advanced VoIP functions, the V85 also provides rich 

telephone features such as last number redial, call forward/transfer, call history, and volume 

adjustment for loudspeaker and handset. NetComm’s V85 is an ideal VoIP solution for next-

generation telephone communication. 

Voice Over Internet Protocol uses Broadband technology to establish a communications link 

between two (or more) communications devices.  In so doing, VoIP bypasses the call charges 

associated with the standard Public Switched Telephone Network (PSTN).
VoIP service providers offer various levels of VoIP service up to a full-service VoIP plan 

which provides for ‘gateway’ access to the PSTN network, allowing you to make and 

receive calls from your VoIP device to the normal telephone network.
Following is a sample of some of the kinds of services available in the current VoIP market.

VoIP devices can be configured manually to operate in a Peer-to-Peer mode by connecting

IP address to IP address; the user stores quick-dial numbers in the device memory 

corresponding to the device addresses of other VoIP user(s). Use of this facility requires 

some knowledge of IP addresses and network configuration. VoIP handsets can be used

in this manner without subscribing to any services provided by a VoIP Service Provider.  

However you still need a broadband connection and router.

A basic VoIP service issues you with a ‘virtual’ VoIP phone number that allows you to 

make and receive VoIP calls to other subscribers on the same VoIP service, normally free of 

charge.

Some VoIP plans have provision to for VoIP-to-VoIP across networks via a ‘VoIP Gateway’.  

Charges for these calls are generally minimal or free.

VoIP-to-PSTN services provide all of the services above, along with the ability to make calls 

to ‘real world’ PSTN telephones - local, Interstate and International – through a gateway 

service. However, PSTN telephones are not able to call VoIP ‘virtual’ numbers so this level 

of service does not provide complete connectivity with PSTN.
