Decided to go VOIP for my landline with 2Talk about 2 weeks ago after getting a ATA device, all seems to work fine except my family in Melbourne can't call me from there Optus landline (says "incorrect or invalid #"), but a Optus cell phone calls my voip line fine and so does a landline or cell in NZ.

Is a local number in CHC 03-928-****, they have tried +643928**** and 00643928****.

Is it my end or Optus end, any help would be appreciated, searched Whirlpool forums and could not find anything.

A party issue on the Optus side they need to open up the number range

My calls from my desk phone at work go out on an Optus PRI, and I can call my NZ and AU 2talk numbers fine

We got Callplus VOIP/SIP at work a year ago (or thereabouts).
(I think Callplus SIP is just 2 talk)
There was any issue with a Northshore (Auckland) number we couldnt call. Could ring fine from a mobile.
Just did nothing from our phones.
Turned out the number we couldnt call was an Orcon SIP number and had 'odd' codec according to callplus. We ended up being able to turn on the codec in the PBX we have and havent had any problems since.

Do you have any control over what codecs you are supporting on your hardware?

Hmm found this settings screen in 2talk.
Once you have logged in to the main 2talk page select the heading "Voice Quality and Networking" on the right side of the screen.
This brings up a list codecs - a couple arent ticked - you could try ticking them and see what happens....

Also - you could try a PC softphone just to check its not your ATA device that is somehow the problem...

Just had a look, only thing not ticked was "iLBC codec supported", so ticked it, don't really know what I am doing in there sorry. I'm sure my ata is fine and I have my Android phone on and "one number" setup so both ring at same time.

A good thing with 2talk is the call log, if your device won't get it due to NAT or something, it will be in call log in your account.

I tried to ring with my PennyTel VOIP (how ever long they last) and it rang 2talk fine.

I think Johnr is correct, maybe that part of Melbourne on Optus does not recognize the CHC 928 number.

So I presume, my brother would have to contact Optus to open the number range up or what ever,
if not I will use a Pennytel Melbourne number and ditch 2talk.

Codecs wont matter. An Optus initiated call will come via the PSTN not a direct SIP interconnect.

investigation starts on A party network not B party network,

It will be simple for Optus to run a trace look at the cause code / release code and then make a call where fault is

Ok,

just had a look at Optus web and it says ->

"International calling from your home phone"

1, Dial '0011'
2, Dial the country code (table below)
3, Dial the area code then phone number (minus the '0' if the number starts with '0')

So maybe instead of 00643928***, it's 0011643928***, will get my brother to try this evening, also when I ring NZ with my PennyTel # the caller ID always says 0064 (NZ), not 0061 (AU)??.

Yes, the IDD prefix in AU is 0011.

It really annoys me when people give their international number out as '00 64' etc. as this wont work from a bunch of countries (Including Australia and the US).

Always give your number out as +64 ... That ways it's dial able from mobiles in that format, and the person dialling can work out what their IDD prefix is.

A number provider should do the analysis

Optus Mobile and Optus Fixed may be routed differently and i would suggest that they dont break out individual NZ codes- i expect it is the NZ supplier downstream from Optus (if nto a dialing digit issue) that has not opened the number range in its switch and as such the call is returning an Invalid Number signal to Optus.

From experience they will route calls to +64 and +642 (Fixed and Mobile) and do not break out individual numbers in New Zealand- now in Australia they will do the full breakout down to switch/carrier/region level but for New Zealand im 95% sure they will not as there costs will be for Fixed vs MObile and hence how they route calls.

Cheers ajobbins,

that is most likely the problem, I never new about the 0011 thing in AU, my brother said he could not get a + symbol from is land line phone, I just tried my hand set and can't either.

So his cell phone was fine with the +64, but was using 0064 on landline, but my Pennytel number rings NZ fine with 0064.

Will get him to ring me later tonight with 001164 # and update.

Cheers

PS, does anyone know how to get the "+" symbol to work on a l/line handset?

You can't. You will always need to dial the relevant IDD prefix from a landline phone. + only works from mobiles.

Protip: If you store all your phone numbers in your mobile in the full +code format, the numbers will work no matter what country you are in.

Even if you are in NZ and you dial +64 2x xxx xxxx from your mobile, your mobile network still knows its a domestic call. But if you are roaming overseas and it's in the 02x xxx xxxx format, the call would fail.
