Hello, just wondering what is common in NZ these days for commercial digital telephony interfaces to the PSTN.
i.e. are most companies using VPN internet connections these days for VOIP or are there still many using ISDN PRI connections ?
For those using VOIP connections, are they primarily all SIP based, or are many using H323 or MGCP ?


Thanks for any info.

Most big phone systems will incorporate both SIP interfaces as well as ISDN PRI/BRI interfaces. There are still plenty of companies to scared to pull the pin on their ISDN even though the SIP trunks tick away nicely with no interruptions.

One example I can think of is a customer we have that has 40-odd SIP channels connecting to their system as well as still retaining the 8 ISDN BRI's they had on their old system. The BRI's don't get used for anything except failover. In 6 months they are yet to have a call go out over the ISDN. The SIP trunks are rock solid.

For connectivity we get a connection from the SIP provider which gives end to end QoS.

The only H323 gear I have seen working was on an old Avaya system which used H323 for the IP phones but had a PRI interface for trunks.

Cant be an accountancy firm then, how many channels did they have before heading down the SIP path or did they just add a SIP card?

For SMB's:

Virtualised software pbx (3CX, PBX In A Flash etc) hosted in decent data centre using sip, ip phones registering from office/home/smartphone/where ever over the internets.

OR just use a provider like Conversant, 2talk, kiwilink for hosted pbx if they/you don't want to manage a software pbx.

Another hosted PBX option is MHA. http://www.mhacloudcomputing.co.nz/

They do Hosted Lync with SIP trunking. Gives you PBX with SIP and Skype connectivity, Instant messaging, Web Conferencing, and integrates with the office apps and other microsoft apps. Integrates with Office 365 too if thats how you roll..

Convince them to get a second broadband link for failover?

Smaller companies are still really reluctant to change out their analogue or BRI systems -- don't fix it if its not broke. Its not like customers ever understood the technology, but plenty of phone techs recommend against VoIP because they aren't IT people or don't want to get IT guys to setup QoS on either LAN or internet.




Time to find a new industry!
