VOIP How To/Troubleshooting Super Guide !

[VoIP Admin]

Dear All

Just thought i put a one stop thread for all VoIP problems that customers may have encountered and also from personal experience dealing with each customer individually over the years.

Calling Card Access Numbers.

Code: Select all

Sydney Access Number: (02) 8205 8300 
Melbourne Access Number: (03) 9013 1900 
Canberra Access Number: (02) 6100 8200 
Brisbane Access Number: (07) 3102 0900 
Adelaide Access Number: (08) 8121 5500 
Perth Access Number: (08) 9467 5500 

Using The Pre-Registered Service (For current customers only)

Once you have registered a number to use with the Exetel VoIP Calling Service you can use that number to initiate a call. To do this please do the following:

Step 1 Dial 02 8207 8900

Step 2 Once you hear the engaged tone - hang up - there will be no charge for this call from your call provider

Step 3 After around ten seconds your telephone will then ring and when you pick it up you will be told how much credit you have and then asked to dial the number of the person you wanted to call.

Service Settings

Username/Auth ID/Display Name : SIP/VOIP number (This can be obtained in the email we sent or via your User Facilities.)
Password : SIP/VOIP password (This can be obtained in the email we sent or via your User Facilities.)
SIP IP : 58.96.1.2
SIP Domain/Realm : sip1.exetel.com.au
Port : 5060

Voicemail Access

Voicemail is activated by default on all DID, you can enabled/disable the service via the User Facilities. To use Voicemail to Email you will need to enable it in the User Facilities and also specify a email address you want the voicemail to be sent to.

Access the voicemail service via the handset can be done by dialling 121.

There is no settings or configurations needed to be completed on the handware. The call will be divert to our VM server if the call is not picked up in 30 seconds.

We always recommend that all units/hardware using on our VoIP service are running on the latest firmware. There are some rare cases that this is not the case.

If you have any problems that are not listed below please upgrade the firmware on the device.

This guide will be kept up to date with all the latest problems and solutions our customers may encounter.

Unit Specific

Netcomm NB9/NB9W Users

If you have problems terminating calls to mobile or certain landline numbers please make sure you are running on the latest firmware.

Latest firmware is NB9W-C211-S306NCM-C04_R02.bin and can be obtained below

http://mirror.exetel.com.au/pub/netcomm ... 04_R02.bin

Latest setup guide for the NB9/NB9W units can be found below.

http://mirror.exetel.com.au/pub/netcomm ... mm_NB9.pdf

Linksys/Sipura SPA Users

Most tickets and support issues are in regards to intermittent voice quality, thanks to CloSeR for the solution below.

Click on the "SIP" tab on the top menu.

Under RTP Parameters configure the following field.
RTP Packet Size: 0.040

Under SDP Payload Types configure the following field.
AVT Dynamic Payload: 96

Change the above settings, then save and restart ATA. If you still find it doesn't work please try changing your SIP codec to G723.

If you have problems calling 121 (Voicemail) you will need to modify the dial plan to the one listed below and change one setting.

Use Preferred Codec Only to "no".

(*xx|000S0<:@gw0>|<#0,:>xx.<:@gw0>|xx.)

Billion Units All 7xxx Series Users

There have been a lot of tickets raised on the quality of the calls on these units. The solution is to make sure that ALL other codecs are turned off.

You will need to manually set G.711 to be used without any other codecs set as priority. This will force all calls made to use the G.711 codec.

Alcatel SPEEDTOUCH 510/530 ADSL ROUTER

If you are using Telstra Alcatel SpeedTouch 510/530 ADSL Router, you will need to unbind port 5060, else VoIP will not be useable. For reasons unknown to man this port is blocked.

To open the port please follow the steps below.

Click on START > RUN > CMD

Then issue the commands below.

Code: Select all

telnet 10.0.0.138 (the router LAN IP) 
nat unbind application=SIP port=5060
config save
system reboot

To check whether it was successful or not issue this command

Code: Select all

nat bindlist

If the port shows as NOT binded you can now start using VOIP.

NOKIA N95 (Thanks to spero for the config)

I have a friend who is about to sign up for the Bundled ADSL1 plan, and I have just been checking for her ADSL/VOIP modem options. I would like to ask two questions please:

1. On the VOIP plan page (http://www.exetel.com.au/voip_planA.php) the modem mentioned as currently available is the Netcomm NB9W, but on the actual sign-up form (https://www.exetel.com.au/bundle/reside ... e_form.php) the modem listed is the Dynalink ADSL2+ 4-Port Wireless IAD (RTA1046VW). I should be glad to know which of the two options is currently available or recommended.
2. If the available modem is actually the DynaLink, is there a VOIP setup guide available for this modem? The NB9W would not be an issue, I know there is a setup guide for that, and it is also my own modem so I would be able to help my friend with her setup.

Help would be appreciated.

[CoreyPlover]

The modem currently offered by Exetel is the Dynalink because they were informed the NB9W is being discontinued by Netcomm. You (or your friend) can still purchase an NB9W from a computer store though if you are more familiar or comfortable with this particularly model. Dynalink modems are just rebadged versions of Netcomm modems and so the configuration pages may even be identical (I have a Dynalink RTA1025W which is identical in all ways except the plastic housing to a Netcomm NB6Plus4W)

Thanks very much.

As a user of the Billion 7404VGP-M router, i'm getting quality issues.

just noticed you say to use G7.11 Codec.

i've noticed in my router config, there is 2 different G7.11 Codec's.

which one is preferred?

PCMU (G7.11 u-Law)
PCMA (G7.11 A-Law)

your help is appreciated.

[ottyacat]

which one is preferred?

PCMU (G7.11 u-Law)
PCMA (G7.11 A-Law)

Ive tried both, both worked but i could not tell the difference in quality between them they sounded pretty much identical to me.

Hi,

I am an existing ADSL2 with phone customer. I have just bought a phone to connect with my Billion 802.11g VoiP ADSL2 router. What do I do next to start making calls?

Thanks

my setup email says Packet Frame Size 20ms (not 40) and G.729 (not either g.711). I have Naked ADSL2+

which is correct? I do get random dropout. The call dies, no noise on the VOIP line at all and it has to be restarted.

Well according to this guide 40ms is the setting to use with G.729:
http://www.exetel.com.au/voip_pdf/voip_ ... ooting.pdf
What model of modem do you have?
If you have a Billion, see page 5 here
http://www.exetel.com.au/pdf/Billion7404setup.pdf
where the G.711a is recommended.

[terrox]

Not sure what to use for Voice Frame Size, 20ms or 40ms?

Is Expire = 240 seconds really a good idea?

[outbush]

Not sure what to use for Voice Frame Size, 20ms or 40ms?

As in my above post.
If you use G729 = 40 ms
If you use G711a = 20 ms
Expire = 240 seconds
Remember G711 uses much more bandwidth, can your connection support this?

[terrox]

Yes I can use G.711 as I sync at 8000/800. Since G.711 is about 64kilobit / sec at 8000/800 connection should be able to handle 10 calls at once (more or less).

But this page http://www.exetel.com.au/voip_faq.htm
Says G.711 cannot accept incoming calls. I think it needs to be updated, either A-Law or u-law should be specified.

EDIT: also, I can not use Voice Mail (dial 121) with G.711 A-Law as it gives a busy signal, but I can use Voice Mail with G.711 u-Law. This is odd considering that A-Law is generally used by all non-US countries according to wikipedia, so people might use it.
