WHAT SERVICE STANDARDS/CALL QUALITY CAN I EXPECT?
- VoIP call quality is similar quality to a mobile call.
- Note that all internet access is provided on a "best effort" basis. No one person, company or organisation owns or operates the internet - instead the internet is made up of a lot of privately owned networks which are interlinked. Since there is no one owner, there is no one place you can complain to. Each provider does their best, but faults do occur, and sometimes these have a ripple affect causing congestion on other routes.
The internet protocols are designed to be fault-tolerant - if a particular path is unavailable or overly congested, packets may find another path. When "surfing" this can result in pages taking longer than usual to display - but voice conversation is more time-critical, and may result in some packets arriving too late, and so being dropped from audio being played at the other end.
- Quality of Service (QoS) support is desirable, because this can give your VoIP packets priority over other data packets. When a large amount of data is to go through your broadband connection, your modem/router will normally send it in the order it is received. With QoS, high priority (i.e. VoIP) data is transmitted before the other data. This minimises the effects of data congestion.
WHAT ARE THE LIMITATIONS OF VoIP?
- Emergency 000 calls: VoIP service providers are unable to pass your street address details to emergency services.
- Power failure: Power failure at your location will almost certainly render your internet modem and VoIP device inoperable. Some VoIP devices (e.g. DrayTek 2100 and 2500) can make PSTN calls during power failure.
- Network outages: As mentioned above, there is no guarantee of availability or 100% quality, due to communication outages or congestion beyond SPANtalk's control.
HOW DOES SPANtalk CONTROL ACCESS?
- SPANtalk cannot currently be used to call Australian 1800, 1900 or 13 numbers; or toll-free numbers in other countries.
- SPANtalk does not have ability to block certain phone numbers (e.g. pay-per-call numbers).
