NodePhone VoIP services have one phone number, but two channels. These channels allow your NodePhone service to carry two concurrent calls. Of course, your VoIP equipment must be able to handle multiple channels to use this feature.
You can increase the number of channels using the 'MultiLine' feature in the NodePhone toolbox. NodePhone MultiLine is often used by business customers for IP PBX systems. Please note that additional charges apply - learn more about NodePhone MultiLine.
You must also check that Call Waiting is set to "On" in the NodePhone Toolbox. By default, Call Waiting is set to "Off" - which will prevent incoming calls from using the additional channel.
Your broadband and NodePhone passwords are separate. If you change your Internode broadband password, it will not change your NodePhone password. Your NodePhone account will keep the password originally assigned to it. This will be the broadband password at the time you created the account.
If you have changed your broadband password, and attempted to update it in your NodePhone service, the service will not register. To resolve the problem you can do one of two things:
In most cases, you do not need to open any ports.
NodePhone, by its design, converts VoIP calls from peer-to-peer mode into client-server mode. Your connection is triggered 'outbound' through your firewall, so you don't need to open the firewall to allow an inbound call.
NodePhone generally avoids any need to configure 'STUN' or other VoIP tunnelling protocols, or to configure special rules to work. For most customers, it is as simple as 'plug in and go'.
Some firewalls manage to block NodePhone. If you need to open up firewall rules, the simplest approach is to open all ports to the IP address 188.8.131.52. All SIP and RTP traffic for NodePhone is originated and delivered via that IP address. Note that this IP address is serviced by a fault tolerant SBC cluster. It is not a single machine, and the system has designed-in security and DoS attack protection.
In some cases, NAT firewalls or ADSL routers contain special features designed to make peer-to-peer VoIP calls work better. These features are called Application Level Gateway (ALG) support.
However, NodePhone does not connect peer-to-peer VoIP calls - all NodePhone calls are automatically client-server calls, connecting outward to our Session Border Controller. Because of this, ALG features can actually stop NodePhone from working - by literally getting in the way.
If you are having trouble getting your device to register with NodePhone, make sure that any VoIP specific 'ALG' features in your NAT device/ADSL router are switched off. This usually solves the problem.
First, check your Internet connection - your NodePhone service relies on it to make and receive calls. If your Internet connection drops out, or suffers performance problems, you may experience call dropouts, or garbled/incomplete calls.
If your Internet connection is OK, check that the cables are all OK, and consider trying another telephone handset.
Finally, check if there is a regular pattern to when calls drop out - for instance, on outbound calls only, or after a certain time. If so, this may indicate a problem with your ADSL router/firewall. In this case, we recommend updating your router's firmware - consult your router's user manual for instructions.
If you have humming, crackling, fuzzy sounds, or other unusual noises on your calls, first check your telephone cables. For example:
If your cables are OK, try another telephone handset. Nearby electronic devices and mobile phones are another cause of interference - especially with cordless telephone base stations. Wherever possible, keep your base station away from devices such as: mobile phones, speakers, microwave ovens, and wireless modems/routers.
Most people use NodePhone through either an Analogue Telephone Adapter (ATA) - such as a Sipura SPA-3000, or an OPEN Networks 812L - or through an Integrated Access Device (IAD) - such as a Billion 740x series router. Some of these devices have their default ringing tone (what you hear when you make an outbound phone call) set to the 'American' style, which sounds similar to the engaged tone used in Australia.
This does not cause any problems making and receiving calls - it's just a different ringing tone than you may be used to.
The ringing tone that is heard on your NodePhone service can originate in two places:
You can change the default ringing tone on a Billion router by:
Echo is generally caused by differences in volume at each end of the phone call. Most endpoints have some form of echo-cancellation or another. If yours doesn't, please consider obtaining one that does.
Some occasional echo is quite normal, even on "normal" phone services, but if it happens all the time, make sure your endpoint's speaker device isn't turned up too loud.
You may even be able to adjust the input gain/output impedance settings in your endpoint, before they hit the audio output device (speaker/headset).
On the Billion 6404/740x series, you can adjust the volume of your handset speaker and microphone, by navigating the web-based configuration screens in the following manner:
Configuration > VoIP > Phone Port > Edit Phone Port 1 > Volume Control
Adjusting these down may help to reduce echo.
Garbled phone calls are usually caused by voice codec mismatches. To fix this ensure your VoIP device uses one of the following voice codecs:
To eliminate this further, make sure both parties of the conversation are using the same audio codec.
This form of codec mismatch is fairly rare these days, and is very unlikely if you use our recommended NodePhone hardware.
A softphone (such as X-Lite/X-Pro) is a program that runs on your computer.
It shares system resources with your computer. If your computer is under heavy load, or experiencing problems, this is likely to affect the quality of your NodePhone service.
To fix problems associated with a softphone try reinstalling the softphone software. Also confirm that your computer is virus and spyware free. Make sure that no software on your computer is using all of the system or network resources.
The single most beneficial improvement for most softphones is obtained by ensuring that you use an off-board headset instead of relying on the built in microphone and speakers in your computer. Examples of this are USB headsets and Bluetooth headsets.
You may be able to, however sending and receiving faxes is not explicitly supported.
In case of problems sending faxes using NodePhone, please over-ride your call to your standard telephone service and use that to send the fax. Or encourage your recipient to consider email instead!
Note: This applies only to Sipura SPA-3000 units supplied and pre-configured by Internode.
Firstly you will need to determine the IP address assigned to your Sipura unit. You can do this by unplugging the PSTN phone line and pressing the star (*) key 4 times (that is: * * * *). When you hear the Sipura configuration menu voice press the following key combination: 1 1 0 #. The IVR will then read out the Sipura's current IP address.
Alternatively you can get the IP address from a DHCP lease table in your router.
The next step is to enter this IP address into address bar of your web browser. A login box should appear. You need to enter the username as 'user'. The password you enter will be your NodePhone password. To then access the Administrator area click on the 'Admin Login' link in the top right corner of the screen. Another login box will appear. The username for this area is 'admin', with the password being your NodePhone password again.
Add the following to your Cisco config:
no ip nat service sip tcp port 5060
no ip nat service sip udp port 5060
