I have a Philips SBX 6 2 line 6 extension phone system. Anyone got any ideas how to interface it to a VOIP system to allow me to >027 to >home phone to >VOIP via a Woosh modem without having to use a computer, or is that too big an ask??


You sure you want to do this over Woosh? Apart from the high latency, Woosh is also limited to a maximum theoretical upstream of 120-125Kbit/s (according to the website documentation). My gut feeling is that call quality would suck under those circumstances.

@Juha  Seems I have a lot to learn.  What is a usable theoretical upstream and is it possible to obtain thru Woosh or do I need a wired broadband connection?

I used "maximum theoretical upstream" because you're on a shared network and thus the speed depends on the amount of users in your particular cell. From memory, Woosh's IPwireless gear can hit 3Mbit/s down, but I don't actually know what the top upstream speed is. However, one reason Telecom's DSL sucks for voice over IP is the 128kbit/s upstream - there are the artificially high 500ms jitter and one second latency in each direction specified as well, but not having enough upstream bandwidth to pass voice audio is a major hindrance.

You may be able to squeeze in a single call in such a low bitrate upstream, but not more. There are people here on GZ who know much more about VoIP, CODECs and bandwidth requirements than I do and can give you better advice, but if you for instance use the G.711 CODEC, you need around 100kbit/s in both directions per call (from memory).

sbiddle: I've already had a friend contact me today wanting to know the cost of building up an Asterisk PBX to interface his 2 home lines. Basically he could save a couple of hundred dollars per month on his mobile by setting up both home numbers as FCN from his 027 mobile. You then dial in and get a dialtone to dialout on the 2nd line for free local calls or toll calls at normal landline rates. You could also use a VoIP provider like iTalk or MyNetFone for outgoing calls and it would be even cheaper.

I can't think of an easy way of doing this without installing Asterisk as a PBX. IMHO the best bet would be to dump the SBX6 and install Asterisk as your main PBX as it's so much better.

Do you have the Woosh phone service or are you wanting to use a different VoIP provider for outgoing calls?

I don't have the Woosh phone service, just Telecom residential, and, as usual, trying to make a silk purse out of a sow's ear, and currently have no VOIP provider and am open to advice, of any sort.  Thanks for the input so far.  Much appreciated.  The PABX you mentioned, can you throw me a link?

trying to use a 3rd party VoIP provider over Woosh is not that good due to the high latency of their network.

For info in Asterisk have a look here

For a newbie I would highly suggest downloading Asterisk@Home which is available as a .iso file which you can install straight off CD onto a spare PC.

Is there a Telecom mobile that can act as a laptop modem? If so then for $10/mth you could call the home computer and use the landline broadband via internet connection sharing (as long as you remember to disconnect every 55 minutes)
