Well, I got my VLAN tagging sorted and now I'm on to trying to get my old phone number that was ported from copper to HomePhonePlus working and after a solid 4 hours, I'm getting no joy.


Anyone here recently get an SPA112 working with 2Degrees?


I'm running into a couple of possible issues:



  1. I tried resetting my VOIP password via their web interface and the directions there are very poor. I *think* you have to enter your broadband password into the current password field and then input their autogenerated password to apply the changes.  I did this and it confirmed the password was changed, but I get password registration errors when even testing on a softphone like Linphone (which works just fine for my SIP account I use for a USA based VOIP account).  Furthermore, when I talked to 2Degrees and asked them if they could send me SIP password, it was not at all the one I changed it to.  Additionally they could see that I changed the password, but their system was showing the original password they have. 

    The question here is - has anyone been able to successfully update their SIP password via the 2Degrees HomePhonePlus portal and still have the SIP device working/connecting?

  2. Any current/updated configuration settings or tips *specifically* for 2Degrees and a SIP device like the SPA112?  I've been given conflicting information about using versus

  3.  Recommended softphone for windows for testing HomePhonePlus from behind a NAT'ed router?  Like I said, I can get through using Linphone with an SIP service from another company in my current configuration with no problem.  Just can't get Home Phone Plus to work at all


Thanks everyone!

Ok...and here's the final follow-up.


Got a good rep on the phone at 2D support this morning and I talked him through the whole situation.  He pulled up my families account notes and in those notes was the SIP password I had been texted.  I read out the SIP password they texted me and he confirmed that was not what was in the account notes.  So this confirms that when 2Degrees texts out passwords their SMS gateways seems to be interpolating and swapping special characters.  Most notably it is having problems with the following characters and swapping them around...there could be more problems, but I could identify at least these:




So, at that point, we were able to find a senior tech at 2D who was able to manually reset my SIP password to a password of my choosing. So I just used a 6-digit alpha password because I didn't want to run any confusion/risk of using special characters.  Once that was reset on my two homephoneplus numbers, they did not register UNTIL I changed the domain from to Once I did that, they instantly registered and both are working.



So, here's what has been established and proven:



  1. Using the portal for HomePhonePlus to change your VOIP / SIP password is broken.  Also, it is very poorly worded and unclear. When you go to try and change your VOIP/SIP password you have to use their generator (you can't choose your own password) and then you have to put your broadband account password in as the current password to invoke the 'Change Password' button (not your current/old SIP password). Then it will accept the change and tell you that your VOIP password has been accepted and you should update your modem and it will send you an email saying it has been changed.  The problem is that it actually hasn't been changed.  So, yeah, 2Degrees has some work to do here.  And, honestly, 2Degrees, if you read all this and decide to rebuild that page....please give us the choice input our own passwords.  Go ahead and enforce strong passwords, but let us pick our own and, of course, make sure it actually updates the systems.

  2. 2Degrees texting gateway is interpolating and breaking special characters. gotta fix that...that's just a recipe for a customer/technical support disaster!

  3. The directions you are providing to customers on your website is not accurate at this page:

    By all indications, the userid (phone number with leading 0) and password appear to be tied to specific servers. If you are registered on you cannot login using  So 2D needs to unify that server structure and credentials system or you need to be able provide us through the portal definitively which server our phone numbers are registered to.


Honestly, someone probably should really consider putting a link to this post into the post pinned at the top of this forum by NickMack about configuring HomePhonePlus for 2Degrees in a BYOD scenario (

Finally, if anyone from 2Degrees does read this, it sure would be a nice gesture of good will if you could credit my account for a month or two of service.  Let's call it a bug bounty prize.  ;)

I spent well over 10 hours debugging this entire situation and uncovered multiple bugs and failures in the homephoneplus network.  Were it not for my ability to troubleshoot this and teach myself how to decrypt encrypted credentials from a working 2D Fritzbox file, I don't know if anyone would have been able to figure out where things were failing since there are 3 significant break-downs / obstacles to getting this working properly.

At the moment I'm experience a strange confluence of relief and pride at having fixed this and having my phones working again and on the other hand I'm exhausted and depressed because I spent all Friday night, about 6 hours on Saturday and 3 hours today trying to get my phone working when the entire problem was 2Degrees was unable to provide me the accurate and working SIP password for my account.
