Q: How much does it cost to ring 13xxxx number?
A: 25 cents untimed. Here's a tip on how to reduce this cost:
Don't call the 13xxxx number directly, rather call the land line number that is linked to that 13 or 1300 number.
You can find out the equivalent land line number from here.
By calling a land line number from our VoIP service you reduce your cost from 25¢ to 10¢.
If you can't locate the land line number from the above link, next time you ring that 13 number just ask the owner/operator what their equivalent land line number is.
Q: What are the difference between different Codecs and which one shall I use with my IP phone or softphone?
A:
When making a call over the Internet, the software (soft-phone) or hardware needs to use a codec to send/receive information in a certain format and convert it to the sounds you hear.
Generally, a codec with a higher bandwidth requirements provides better voice quality (If your Internet connection is fast enough to support the codec). Most VoIP providers/hardware/licensed software will support G.711 and G.729 (However be sure to check this before purchasing hardware, or signing up with a VoIP provider!). The G.711 codec requires a connection almost 3 times faster than that required by the G.729 codec.
If you are using a free soft-phone, then G.729 will not be available to you; however, the GSM codec should be, and will give you similar call quality to that of a mobile phone.
The following table shows bandwidth requirements for many common codecs. For more informatio on codecs please refer to this Codecs Wiki.
Codec.................Bandwidth Usage (Up/Down)
G.711 (64 Kbps).......87.2 Kbps
G.729 (8 Kbps)........31.2 Kbps
G.723.1 (6.3 Kbps)....21.9 Kbps
G.723.1 (5.3 Kbps)....20.8 Kbps
G.726 (32 Kbps).......55.2 Kbps
G.726 (24 Kbps).......47.2 Kbps
G.728 (16 Kbps).......31.5 Kbps
GSM (7 or kbps).......low
ILBC (low)............low
We recommend you to use G.711 (ulaw or alaw) with our VoIP services if you are on an above 512M broadband connection. Using this codec you can have "Hi-Fi" quality sound.
If you are on a slower 64k ADSL connection then the G.729 codec is more suitable (it will lose some sound quality due to compression but will give you an overall acceptable audio).
Q: Does credit expire?
A:
Your CnCn credit is valid for 1 year.
Q: I get X-lite registration error 404, what shall I do?
A:
Please make sure your username and password are correct. You can type them in rather than copy and paste from the email received from CnCn.
A lot of the cases when copy and paste there is an extra space added to your username thus making it incorrect.
Q: How to solve X-lite "Request Timed Out" error?
A:
This usually indicates a network connection problem at your end that is blocking your VoIP traffic. Please try shutting down any firewall you have in your PC or router and see if it solves the problem.
Please make sure UDP port of 5060 and UDP ports from 10000 ~ 20000 are open from your end. For information on how to configure your particular router please Click Here (opens a new window). Choose your brand of modem/router and then on the next page click "X-lite".
