The OPEN Networks 824RLW is an ADSL 2+ Modem with Router, 802.11b/g Wireless Access Point with WPA support, 2x VoIP phone lines, Lifeline PSTN and 4x 10/100Mbps LAN ports.
In essence the OPEN Networks 824RLW is a Rebadged Billion 7404VGP but much cheaper at about $110 with a few small differences: no Annex M faster ADSL2+ upload (but most ADSL2+ plans dont support Annex M anyway), the OPEN comes with an ADSL combined splitter/filter where the Billion just has a filter and the OPEN has 1yr warranty/Billion has 2yr warranty.
I don’t need ANNEX M support so I bought the OPEN 824RLW for $109+post instead of the Billion 7404VGP which sells for $165+
- Brilliant value because its at least $60 cheaper than the Billion 7404VGP which has almost exactly the same features
- As an all in one solution you don’t need a separate VOIP adaptor using up an extra power point. My new OPEN 824RLW replaces my old setup of a Zyxel ADSL modem/router + Sipura 2100 VOIP adaptor.
- The 824RLW supports downstream speeds up to 8Mbit with ADSL1, 12mbit for ADSL2 and 24 Mbit with ADSL2+.
On my 8MBit ADSL1 plan with Internode I connect at Downstream: 7.616mbit, Upstream: 0.384mbit
The fastest speed I’ve heard any getting with an ADSL2+ account is Downstream: 24.575mbit, Upstream: 0.927mbit
Both these speeds are pretty much the highest possible unless you live 5 metres from your telephone exchange so the 824RLW will probably get you the highest ADSL speed that your phone line quality allows.
- Automatic fallback back to Landline PSTN to allow you to make normal phone calls when there is a power outage, or when the Internet connection is down.
- Having VOIP built in allows the 824RLW to use Quality of Service (QoS) to give VOIP phone calls priority, even when you’re downloading large files etc
- Individual LED’s on the front of the modem light up green when VOIP Phone1, VOIP Phone2 or the Landline PSTN are being used to make calls
- There’s a very similar ADSL mode/router also called the OPEN 824RLW 3-port being sold for a similar price as the OPEN 824RLW 4 port. Don’t buy this 3 port version because you won’t save any money and it’s a rebadged Billion 7402VGP with less features than the OPEN 824RLW 4 port
- OPEN Networks Firmware looks like it will probably not be able to upgrade beyond 5.53 which suffers from garbled voice with G729 VOIP codec. Easily fixed by using g711a or g711u codecs instead by going to the admin menu:
“Configuration -> VoIP -> Phone Port -> Edit (line 1 or 2) -> Codec Preference -> Priority 1”. Choose G711u or G711A depending on what your VOIP company recommends. I use G711U with Mynetfone
Firmware + Other Tips
The Billion firmware is a bit more user friendly with VoIP in particular, having the common Aussie VOIP companies pre-defined and having the default dial plan push 000 calls to PTSN is a wise move.
