Modem FAQ
RingCentral Modem
Tuning Utility
Setup (Modem Tuning Utility, MTU) identifies your modem(s) and
tries to match it against RingCentral modem database. Because most
modem drivers are not 100% TAPI compliant, the database contains
workarounds that can be applicable to certain groups of modems. Once
your modem is matched, it will belong to one of known groups, so
that workarounds for certain problems will be applied. We compiled
the database of over 200 modems, those sold in stored and those
bundled with PCs.

Modem Capabilities
Voice
With regard to different RingCentral products, there are 2 types of
modems - voice and data/fax. Data/fax modem used with the software
such as RingCentral Fax (or RingCentral), provide fax/data
send/receive functions. In addition to data/fax modem functionality,
voice modems have voicemail/answering machine functionality. To use
it, one needs software such as RingCentral (not RingCentral Fax).
In addition to voice capability, there are few more worth
mentioning capabilities:
Speakerphone (voice modems only)
Speakerphone modems allow you to have a speakerphone conversation in
addition to voicemail features. For this reason, voice modems
without speakerphone are typically dubbed "voicemail modems". Most
voice modems have speakerphone capability.
Caller ID
Caller ID can be used in conjunction with such RingCentral features
as Private Greeting and Local Announcement (Distinctive Prompt).
Most modems that come with PCs do not support Caller ID, although
this may vary depending on the price tag.
Handset
Handset socket lets you plug a phone handset into the modem. Handset
feature can be used with data/fax modem as a speed dialing (or
dialing using calling card) - you can dial a number or sequence of
numbers using RingCentral, then pick up the handset and have a
regular phone conversation. In addition you can use handset to
record a greeting and listen to messages with a voice modem.
Call Screening (speakerphone modems only)
Call Screening capability lets you screen voice messages as they are
being left on RingCentral answering machine.
FAX Class 1, 2, 2.0
Provides fax send/receive functionality.

How to determine modem capabilities?
If you are not sure whether your modem has voice capability,
there are a few ways to check it:
1. Run RingCentral Modem Setup or Modem Detection and see
reported capabilities
2. Read the modem/computer specifications or contact your
modem/computer manufacturer
3. Check whether modem wave device is present in the Device
Manager (Windows 95,98,2000)
Wave device presence indicates voice
capable modem, given that correct modem driver is used:
1) Click Start Menu > Settings > Control Panel
2) Double-click System icon. You'll see System Properties dialog.
3) Select Device Manager tab.
4) Open Sound, video and game controllers branch.
A. Wave Device for Voice Modem
is listed - then wave device is installed
B. Wave Device for Voice Modem is listed and marked with a
(!) - there is a problem with it. In such case, reinstalling modem
drivers recommended
C. No Wave Device for Voice Modem listed - the modem is not
voice capable or the modem driver is installed incorrectly
4. Run Windows modem diagnostics to get information about
the modem (Windows 95,98)
1) Run Windows modem diagnostics
2) After Windows has queried the modem and received responses, note
the response on AT+FCLASS=? command. It may look like "0,1,8,80".
Usually number 8 indicates voice capability, number 80 -
speakerphone capability.
NOTE: Sometimes modem driver can contain a mistake and response
on AT+FCLASS=? may be misleading.

Windows Modem Diagnostic
You can check your modem using Windows Modem Diagnostic tool. If
modem does not pass the Windows Diagnostics, RingCentral will not
"see" that modem.
NOTE: If you use modem to connect to the Internet, you will need
to disconnect before you can proceed with modem diagnostics. It is
recommended that you print out and retain this page for reference.
1. Close all communication applications.
2. Click Start Menu -> Settings -> Control Panel
3. Double-click Modems icon. You‘ll see Modem Properties
dialog.
4. Select Diagnostics tab.
5. Highlight the COM port where your modem is installed.
6. Press More Info... You should get one of these results:
A. More Info dialog with
commands and responses.
B. Empty More Info dialog or no response.
C. Error message (typically "Can‘t Open Port").
7. If you have more than one modem in the list, repeat
steps 5-6 for each modem.
Result A normally means your modem is installed and working.
Result B: (Windows queried the modem but received no
response)
Check that modem is turned on and
connected properly to the computer (if external modem)
Reinstall modem driver
Result C: (Windows is not able to access the port)
Check that all communication programs
are closed
Check that modem is turned on and connected properly to the computer
(if external modem)
Reinstall modem driver
Check that there are no hardware conflicts in the Device Manager
It is essential that IRQ and I/O addresses are configured correctly
Contact your modem/computer manufacturer for further assistance
in this matter.
If you see two different modems on the same COM port, it means you
have two different drivers installed. It could be because you use
different PC card modems in your notebook PC or because different
drivers and/or modems were installed in the past. We recommend
removing driver for a modem which is not used.

Windows Dialing
Properties
RingCentral uses Windows functions to dial calls. In turn, those
functions work according to settings in Windows Dialing Properies.
Windows Dialing Properties are accessible via Start > Settings >
Control Panel > Modems > Dialing Properties.
NUMBERS ARE FOR ILLUSTRATION PURPOSES.
YOUR NUMBERS MAY BE DIFFERENT.
RingCentral does not "know" about area and country codes, dialing
"1" in front of a phone number, about calling cards, call waiting
tone and other settings from Dialing Properties. Solution for most
dialing problems lies in Windows Dialing Properties dialog. If you
have problems dialing calls, check the following items in Dialing
Properties first:
Location: First of all you need to make sure your location is
set correctly. If you are located in 650 area code, but your
location setting indicates 415 area code, all calls to 650 area code
will be dialed as long distance, because Windows "thinks" you are in
415 area code. If you are located in UK, but your location is set to
USA, all calls to USA will not be dialed correctly for the same
reason.
Call Waiting: If you do not have the call waiting on your
phone line, but your Dialing Properties instruct Windows to dial
*70 to disable call waiting, you will most likely get an
operator message as soon as Windows (or RingCentral) dials *70.
Uncheck this box if you do not have call waiting
Outside Line Access: If you're behind a PBX, and you need
RingCentral to dial 9 before the phone number, set 9
in the fields To access an outside line.
Area Code Rules: Windows 98 provides advanced Area Code Rules
in Dialing Properties to specify how non-standard calls should be
dialed. Read this if you cannot place calls to the phone numbers
that require dialing a "1" plus area code, even to the numbers
within the same area code, OR you cannot place calls to local
phone numbers that require dialing an area code, but do not require
dialing "1" before:
Example 1
You are located in 650 area code and you need to dial the number
1-650-555-1212
In Area Code Rules:
- enable Always dial the area code checkbox
- in Dial 1 for the numbers with the following prefixes,
create new entry 555.
NUMBERS ARE FOR ILLUSTRATION PURPOSES.
YOUR NUMBERS MAY BE DIFFERENT.
All calls to 650 555 xxxx will be dialed as 1 650 555 xxxx
now. All other calls to 650 area code will be dialed as 650 xxx
xxxx
End of Example 1
Example 2
You are located in 650 area code and you need to dial the number
415-555-1212
In Area Code Rules:
- in When calling to other area codes, create new entry
415.
NUMBERS ARE FOR ILLUSTRATION PURPOSES.
YOUR NUMBERS MAY BE DIFFERENT.
All calls to 415 area code will be dialed as 415 xxx xxxx
now.
End of Example 2
Advanced Area Code Rules: If your location has rules that are
more complicated than Windows Dialing Properties can handle, some
hints are required to obtain needed results. To learn them please go
to the Knowledge Base and view corresponding articles.
Area Code Rules in Windows 95: There are none, therefore some
hints are also required. To learn them please go to the Knowledge
Base and view corresponding articles.

Modem FAQ
What is a voice modem?
A voice modem is a data/fax modem plus additional voice chip which,
in combination with software such as RingCentral, delivers you a
functionality of a digital answering machine and voicemail. Most
voice modems also have speakerphone function.
What is a modem driver?
Modem driver is a software that needs to be installed in Windows to
make modem work. A modem driver typically contains command sequences
that are sent to modem by Windows to do different tasks (e.g. dial a
number, record, play, enable speakerphone and so forth). For soft
modems, modem driver also includes a software component to emulate
certain modem functions.
What is a soft modem?
Soft modem (controllerless modem) contains minimum hardware on its
board. Instead, it employs a software component (also referred to as
a driver) which uses host CPU to emulate modem functions. This
component "talks" to modem hardware in a proprietary way.
What is a modem chipset?
Modem chipset is usually named after the manufacturer of the main
chip on the modem. Various modems from different manufacturers can
have the same modem chipset. If a communication application works on
a modem with a certain chipset, it will most likely work on another
modem with the same chipset. The well known chip makers include
Lucent, Conexant/Rockwell, TI(USR), Motorola, Cirrus Logic, PCtel.
What is "TAPI compliant"?
This is a technical jargon meaning that in order to work with the
modem, various communication applications can use TAPI - Microsoft‘s
standard "language" to work with various modem hardware.
Applications using TAPI are also called TAPI compliant. RingCentral
is one of them.
