For the past week I've been working on some New Zealand specific setup files for Linksys phones and ATA's.
The configuration settings that are listed in numerous websites in NZ do not have a complete set of New Zealand tones (and some are wrong), have incorrect FXS settings for the NZ line impedance (which can cause echo if you're using an ATA) and have a poor dialplan.
I've worked through the Telecom TNA102 spec which defines tones in NZ and have also spent a lot of time working on a dialplan which will allow calling virtually every number in NZ with no delay - ie when you dial 041234567 it matches this immediately and connects the call with no delay.
My plan is to very soon make a blog post live which contains all of these settings. I will also be hosting a .cfg provisioning file that will allow people to set a provisioning rule in your phone or ATA and download all of the correct settings to your device. It will not override any account settings in your device, it will just set the dialplan, tones, FXS impedance, timezone, daylight savings rule and a couple of other minor NZ specific settings.
I'm undecided at this stage of a couple of things including whether I should leave the provisioning rule enabled (so once per week it would check for a new updated file) or disable this after it downloads the settings.
Right now I'm after some feedback from people about this idea and also after a few people who are interested in testing this. If you have a Linksys device connect to VFX this won't be of any interest to to as WxC provision your device with the correct settings. I'm aiming this at people who are either their phone with their own PBX such as Asterisk, or a service such as iTalk, 2talk, Orcacom etc that all have the incomplete or incorrect settings available on their support websites.
While the risk is very minimal as always there is a risk of things going wrong so if you're not comfortable reconfiguring your device if something did go wrong it's probably best you don't test it!
