Hi Lakeman,

Thank you for responding to my post. After seeing your success, I decided to give it another try. Previously, I dialed nnnnnnnn, 02nnnnnnnn, +612nnnnnnnn and had no success. This time,I dialed 612nnnnnnnn, and my home phone rang! I have not got my wife to pick it up as it of 1am in the morning now. Tomorrow i'll test the sound quality. I'm using pennytel. In the past I've been using sjphone client. The sound quality is okay provided I use headset. Did you try talking with the headset? It eliminates echo on the other end. Without headset, the other guy's voice from the speaker goes back to the microphone and he can hear his voice played back to him .

Thank you once again for giving me the assurance that it can work in Australia.

Edit: I'm having problems. When I called my home number, my wife picking up the call could hear me, but I could not hear a thing. Also, using the same method of calling other number does not seem to work. I'm also unable to call mobile numbers.

With Pennytel as my SIP provider, when using Sjphone, I dialed 02nnnnnnnn for landline and 04xxxxxxxx for mobile, +61 1300xxxxx for special numbers.

With the built-in VOIP, the above dialing method seems to work differently. I thought that dialing 612nnnnnnnn for landline would work as the phone actually rang, but it does not really work fully. Dialing 04xxxxxxxx basically kick the phone application out. If I dial 0011612xxxxxxxx and 0011614xxxxxxxx, my phone shows that it is connected, but I can't hear a thing from the other side. I don't know if the other side could hear me.

Anyone using Pennytel in Australia who manage to get it working? I think I would try to work with Pennytel to sort this out.

Edit: Pennytel's help desk know next to nothing about this. Amazing how they could run a VOIP company.

Anyway, looks like WM6 only supports g711 and gsm codec. My VOIP provider uses G723 and 729 and gsm. I'd have to find ways to switch the codec to gsm to see if it works. Found this post which outlines the registry edit in order to add gsm codec and to switch between g711 and gsm for those of you interested:

QUOTE Sleuth255

Make these Registry changes / additions

hklm\comm\rtc\codec

UsePreferredCodec DWORD=1

PreferredAudioCodec DWORD = 0 or 3 (3 = gsm, 0 = g711)

hklm\Comm\RTC\ACM\GSM

hklm\Comm\RTC\ACM\GSM\PayloadType DWORD = 3

hklm\Comm\RTC\ACM\GSM\FrameDuration DWORD = 20

hklm\Comm\RTC\ACM\GSM\CodecRank DWORD = 1

hklm\Comm\RTC\ACM\GSM\UseHealer DWORD = 1

hklm\Comm\RTC\ACM\GSM\Driver String = gsm610.acm

hklm\Comm\RTC\ACM\GSM\WaveFormat\FormatTag DWORD = 49

hklm\Comm\RTC\ACM\GSM\WaveFormat\Channels DWORD = 1

hklm\Comm\RTC\ACM\GSM\WaveFormat\SamplesPerSec DWORD = 8000

hklm\Comm\RTC\ACM\GSM\WaveFormat\AvgBytesPerSec DWORD = 1625

hklm\Comm\RTC\ACM\GSM\WaveFormat\BlockAlign DWORD = 65

hklm\Comm\RTC\ACM\GSM\WaveFormat\BitsPerSample DWORD = 0

hklm\Comm\RTC\ACM\GSM\WaveFormat\bSize DWORD = 2

Once after adding all above settings, only changing the following setting will be enough to change between GSM and g711 :

hklm\comm\rtc\codec\

PreferredAudioCodec DWORD = 0 or 3 (3 = gsm, 0 = g711)

As for dial plan, Shaun33, the author of SIP Config tool, promise this will be in the next version. This should save me the headache of having to put in all the prefix in front of my phone numbers.
