I'm thinking about ditching the landline and switching to VOIP, but really have no idea how to go about that. Or even if it's a good idea. Is there a "How to switch to VOIP in NZ" guide available somewhere? I found this but it's from 2009... I guess it's no longer totally correct?
I currently have my home landline and broadband (ADSL, soon to be VDSL, fibre's not even on the horizon :( ) with Spark. Wifi is accessible throughout the house and over most of the section. Currently my phone system is a cordless base station with answerphone and 2 handsets. Modem, computer, and phones are on UPS for comms in an emergency. The main use of the landline is just for incoming calls, because I never use all my cellular free monthly calling minutes anyway.
Some specific questions:
- Is VOIP worth bothering about? Should I just throw away the whole landline, not bother with VOIP, and just use cellphones for voice calls? If I do this, I guess I can get my landline number redirected to my cellphone? Any other gotchas with ditching the landline?
If I go with VOIP, can I keep my existing phone number? If I can't, all the rest is pretty much moot, I think. It would be just as easy to tell everyone my cellphone number as to give them a new VOIP number.
- Assuming VOIP is still a good idea...
- Can my family use their cellphones over WiFi to answer incoming VOIP phone calls? Or can I get multiple VOIP handsets that answer the same number and work over my Wifi? I guess I'll need to install some kind of VOIP/SIP software on my desktop (Ubuntu Linux 16.04) for either of those solutions?
- My HG659B modem says it supports VOIP and has a "Phone" port. Presumably I could just plug my cordless base station (2 handsets, answer phone) into that, and don't need an ATA?
- From the modem manual, it appears I need a VOIP provider. Would that be Spark? Or how about 2talk? Or someone else?
Any other suggestions or comments would be welcome.
