2talk

2talk is a New Zealand and Australia–focused VoIP provider. Plan-based pricing in NZD, NZ + AU geographic numbers, and SIP credentials handed out as part of every plan — no separate “BYO device” tier to opt into. New accounts land on 2talk’s Lyra platform (the older Asterisk-era hosts are being phased out).

What you’ll need from 2talk

1. Sign up at 2talk.co.nz and pick a plan that includes at least one number. The free GO FREE plan is enough to test (15 NZ national minutes, 1 trunk, 1 toll-free number); a real personal plan starts at 2TALK 10 (NZD $10/mo ex GST) — see pricing below.
2. Find your number’s SIP credentials in the 2talk dashboard. Each 2talk number is its own SIP registration:
   • Username — the 2talk number itself, in full international format (e.g. +64XXXXXXXX for NZ).
   • Authorisation username — same as the username.
   • Password — per-number SIP password. Defaults to your 2talk account password until you explicitly set a different one for that number (recommended for security; the dashboard lets you set a number-specific password).
   • Registrar / proxy — lyra.2talk.co.nz for all accounts on Lyra.

The full set of authoritative SIP settings is in 2talk’s Lyra SIP Settings guide.

Fields for WaveKat Voice

The preset also sets Refresh sign-in to 600 seconds — matches 2talk’s documented Register Expires: 600 seconds. Other Advanced defaults are fine (UDP, port 5060). If you’re behind a NAT and see calls dropping, set Keep-alive to 60 (2talk’s recommended NAT keep-alive interval).

Optional: TLS for encrypted signaling

2talk supports SIP over TLS on port 5061 for accounts that want encrypted signaling. To enable it in WaveKat Voice: open the account’s Advanced section, set Connection to TCP (TLS isn’t a separate option today; track this issue for native TLS support) and Port to 5061. Most users can leave this off — UDP on 5060 is the default 2talk recommends and what the preset configures.

Test it

After saving, the green dot on your 2talk account chip on the WaveKat Voice Home screen confirms you’re registered. 2talk doesn’t publish a public echo test number, so:

1. Call your own 2talk number from another phone — WaveKat Voice should ring.
2. Or call a friend’s mobile and confirm two-way audio.

Common gotchas

• 401 Unauthorized on sign-in: by default your number uses the 2talk account password as its SIP password. If you’ve set a per-number SIP password in the dashboard and forgotten it, reset it from the number’s settings — the dashboard generates a new one. The Authorisation username is also the number itself, so if a leading + got stripped on the way into the form, sign-in will fail.
• Calls drop after a few minutes: NAT timeout. Set Keep-alive to 60 in Advanced. If that doesn’t help, switch Connection to TCP — some routers handle long-lived TCP connections better than UDP heartbeats.
• No incoming calls: confirm the number is enabled and pointed at the registered SIP endpoint in the 2talk dashboard. On multi-trunk plans, inbound routing has to be explicit per number.

Pricing

2talk’s pricing page is authoritative. As of writing, voice plans (all NZD, ex GST):

Calls over plan: NZ fixed @ 3c/min, NZ mobile @ 15c/min (ex GST). All plans include SIP trunking and cloud PBX features — no separate “BYO device” tier or fee. Cheaper than per-minute global providers (Twilio/Telnyx) for NZ/AU traffic; not competitive for outbound to other countries.
