My brother-in-law has just moved to NZ and has just got broadband and phone with Orcon. From what I understand he's on the basic Orcon@Home 5GB package.
He tells me his phone plugs into his router, so I'm assuming his phone line is therefore SIP. I had hoped to be able to call him by SIP URI (therefore bypassing the PSTN network), but I've tried using the SIP URI <accountnumber>@sip.orcon.net.nz where <accountnumber> is his Orcon account number. I've also tried using his phone number, but in all cases this fails.
Do Orcon permit incoming calls by SIP URI? If so what am I doing wrong?
If they don't is there anything stopping us using a SPA3102 ATA or an IP phone and signing up with another VoIP provider who does? Really just checking that Orcon don't block the use of other SIP services on their network.
Also are there any NZ VoIP providers who offer a free Auckland DID? Everyone I've found wants to charge you for it.
Thanks in advance.
