What's mtctel
telephone? What's the difference between mtctel and
regular phone?
The mtctel is a kind of Net Phone which connects
directly to USB port of Personal Computer. It looks like
regular phone including standard phone key pad and most
of regular phone functions, such as touch tone, ringing
tone and etc. However, it indeed is a kind of USB voice
device. All communication protocols and voice are in
strict accordance with the computer and internet
protocols. So we can say that it's a "phone-like" USB
device. The regular phone uses switching technology. It
has a center switch that distributes voice and signals
directly to each phone. Therefore, you can hear dial
tone when picking up handset, but mtctel not.
Is mtctel a legal product?
mtctel adopts the same communications technology as that
of Skype (The company was purchased at a sky-high price
of $4.1 billion last September by eBay, a well-known
U.S. international auction company). The technology is
completely legal with the evidence of Skype winning the
case of FCC that many international communication
operators sue the Skype in 2004.FCC gave two reasons for
the judgment. In the first place, the global
communication backbone has become public property which
shouldn't be charged in monopoly by a few communication
operators. In the second place, users have rent and paid
for the broadband. Now that the communication operator
can realize data communication service on voice service
line, why can't users realize voice service with data
service on the same line?
Which countries and regions can mtctel reach now?
We currently cover all of landline and mobile phone for
North American, Mainland China, Hong Kong, Thailand and
Singapore. Also, we cover landline phone for many Asia,
European and other countries and regions, such as Japan,
Taiwan, South Korea, Malaysia, Australia, New Zealand,
Argentina, Chile, Austria, Denmark, Finland, France,
Italy, Liechtenstein, Luxembourg, Monaco, Netherlands,
Norway, Portugal, Spain, Sweden, United Kingdom and etc.
Why mtctel has no jamming over Internet?
It depends on the current three types of VoIP. The first
is VoIP using .323 protocol (the technology used by the
common phone cards). It needs a VoIP server respectively
on the calling side and receiving side. When the server
on calling side receives a call, it will convert the
call into an information pack and send the pack through
internet to the server on the receiving side. The server
on the receiving side will then transfer the call to the
local telecom network. This structure has limited number
of phone lines linked to the servers on both sides.
Jamming will occur when users call at the same time.
This is especially true on holidays when it is quite
common to spend 30 minutes or more to get through.
The second type is SIP (also known as soft switch
technology). It uses caller's computer to process the
caller voice into VoIP with SIP label and then send it
to the destination telecom network gateway directly. For
instance, someone flies to Beijing from San Francisco
virtually and to dial the number on Beijing local
telecom network, so no jamming will occur. At present,
mtctel has adopted this technology.
The third type is P2P technology that is similar to SIP
in voice communication. However, the main characteristic
of P2P technology is its capability to stream large
volume multimedia contents. Voice communication is only
one of its functions. The quality of P2P voice
communication is not as good as SIP sometimes since most
of the telecom exchange gateways are not completely
compatible with P2P protocol.
Is broadband required? Does dial-up work with
mtctel?
Broadband service is requited, such as XDSL, Cable
modem, and LAN.
Can I receive such calls from regular phone line?
Not right now as it is related to the telecom providers.
It could be possible if the cooperation with the telecom
providers is established.
Currently a 16-digit Universal Phone Number System has
been developed. With this universal number, you could be
reached through any phone from anywhere in the world.
This 16-digit number could be found on the bar code
printed at the back of phone set.
How to dial international long distance
correctly? Do we need to add country code for local
dialing?
The correct dialing procedure is: (country code) (area
code) (phone number). For example, mtctel phone number
in North America is 778 239-1586, of which, 778 is the
area code and 239-1586 is the phone number. The country
code for USA is 1. Therefore, the correct dialing is
17782391586. Take Chinese city Guangzhou for another
example. The local number is 8266588, the area code 010
and the country code 86. The correct dialing is
86108266588. Please notice that the first 0 of 010 must
be deleted while dialing.
Local calls should also follow the principle that the
country and area codes be added while dialing. For
instance, the correct dialing is 8610xxxxxxxx if the
call is made from Beijing to a Beijing local number.
Why there is no signal when I pick up the
Internet phone?
Internet phone does not have the exchange switch which
is the major difference between a regular phone and an
internet phone. For an ordinary phone, the exchange
switch will produce a long steady signal when the phone
is picked up. There is no exchange switch for web phone
to produce such signal. However, you can hear a dialing
signal when you dial a number.
Can I dial an extension?
Yes.
Why does the computer screen flash several times
when I use mtctel for the first timer?
When you use mtctel for the first time, built-in
software will scan the USB port to see which port has
installed mtctel. When the port is found, the parameters
will be configured automatically without any manual
operation.
Can I dial emergency numbers like 911 with
mtctel?
You can do that, but since the receiving party cannot
see your phone number, your call may not get immediate
response. Therefore, mtctel has a clear notice that
BL-05 is NOT for emergency use.
Can I dial free toll number 800?
Yes.
Can I dial some specially charged numbers in
places like the United States?
No. (But in Chinese mainland and Taiwan, some charged
phone systems do not shield VoIP.)
Can I cancel my regular phone service after
using mtctel?
We do not recommend you cancel your regular phone
service because mtctel is currently not able to take
incoming calls. If you have no other substitutes (such
as cell phone), you'd better keep your regular phone
service and set a minimum service package to save money.
Can I talk with a headset microphone instead of
an mtctel?
No.
Why does interruption (or delay) occur during
the conversation?
This problem is caused by low speed network connection,
especially for customers in China whose xDSL connections
cannot reach the broadband standard. There will be
quality issues if network connection is lower than
64Kbps. The following web site could help you check the
speed of the connection.

Strong recommend that
you close all your downloading programs such as any
browsers and games when you make a phone call because
any downloading will take the traffic spaces, which
affect your calling quality.
Please connect the internet with the cable rather
than wireless connection if you can. Wireless is not as
stable as cable when you make a phone call.
Why does disconnection occur occasionally after
a few minutes talk online?
It's quite complicated. In addition to the network
reasons, the call could be affected by PC performance,
firewall configuration and using habit. As discussed
above, this is an Internet phone with a data stream
higher than 40Kbps. If user opens many applications or
web sites, PC resources could be overly consumed. Also,
applications may have frequent data exchange with hard
disk cache. If the hard disk is full of data, the
exchange time will be extended. When the exchange time
is longer than 300ms, voice package could be lost, which
leads to disconnection of the call. Also, some virus
detection program may terminate normal voice call.
Our recommendation: turn off other applications and IE
when you are about to make a call.
How to recover the system after break down?
As this Internet phone set is being used with different
types of PCs, old and new, USB interfaces could be
jammed sometimes with following situations: a).
Legitimate user, but leave the line unconnected for long
(Normally a legitimate user will be automatically logged
on 10s after picking up the phone. But sometimes the
user fails to set up connection after trying several
times on-hook and off-hook. b). User couldn't see mtctel
interface after picking up the phone, although the
microphone icon at the lower right corner of PC screen
is green. Sometimes, the icon is red even with phone
connected to PC (Note: you could use an USB drive to
make sure the USB interface is OK.). There might be
other problems. Re-plug phone set to the USB interface
or try another USB interface and restart your PC to see
whether the problems are solved. If it is still not
working, restore the system with following procedure:
STEP 1: Find the microphone icon at the lower right
corner of PC screen.
STEP 2: Right click the icon
 .
The system will let you choose between: "run" and
"quit". Choose "quit", and the icon will disappear.
STEP 3: Find the big green icon of microphone on your
desktop. Double click the icon and you will find the
microphone icon at the lower right corner again, which
is green first, then red, and finally turns green (make
sure phone is connected to the PC). Now you can make
phone calls.
Another way to terminate the program and then restart it
is to hold "Alt+Ctrl+Del" to open "Task Manger". Kill "shellvoip.exe"
and "voipstunt.exe" files at "Processes" tag of "Task
Manager". After "End Process", start the "shellvoip"
icon on desktop.
For E108 customers,
it is better to hang up first by press the power button.
If does not work, unplug the USB and reinsert it into
USB outlet in the computer. |
