NTL & Sipura 2100 or Handytone 486?

mrblack

I have BB with NTL and am stuck as to which of the above ATA's are bestsuited for me. Actually I am not sure if I need an ATA with a router function at all. I have a Buffalo wan set up at the moment if that matters in addition to the NTL cable modem.

Any good advice is welcome

thx

Either would be fine. Do you need the 2 FXS ports on the Sipura 2100? Typically you'd have a SIP account for each port.

You can just plug the ATA into the Buffalo (assuming you've got free LAN ports) so the ATA doesn't really need the router functionity.

Well I was thinking of having 2 VOIP a/cs. Probably one with Freespeech or Blueface and one with VOIPcheap/another

Right, but whats the point of an ATA having router functionality as well if you must already have a router from your BB provider? Is it possible to ditch the NTL BB cable router and just use the Sipura 2100 (by spoofing the Ntl MAC address on the 2100). This would save some clutter in the living room corner. Then I could just plug the Buffalo wan into the sipura and bobs my uncle. Right or wrong?

It's not possible to ditch the ISP's Modem in the case of cable and wireless ISPs. The only time you will easily, relatively speaking, be able to swap out the modem is when you have standard ADSL (i.e. an Eircom bitstream DSL derived product not Smart/Magnet ADSL2/SDSL etc.) and you can then swap the supplied Modem/Router with something like a FritzBox ATA/Router/DSL Modem combo or just a different DSL Modem/Router combo.

A lot of ISP's don't provide a modem with an inbuilt router. Clearwire, IBB and NTL are all examples. The boxes with their products are just straight modems. In some cases you can get or will be given a separate router by your ISP and in htose cases you can swap the supplied router easily enough from a technical standpoint although you may have support issues with your ISP if you need help from them to set it up.

In NTL's case you will have to leave the modem they supply in place and you would generally need to get either a separate router, which it sounds like you have, or an ATA/Router combo. In your case since you already have a router getting an ATA with an inbuilt router is of no real theoretical advantage. However most ATAs these days do come with in built routers and I definitely would not go out of my way to find one that doesn't as the price difference will be small or non-existent. You can also use an ATA with an inbuilt router just as easily if not more so then one without, even if it's plugged into a spearate router, and for VoIP you will have a LOT LOT less problems if your ATA is able to plug directly into your ISP's modem rather than through an intermediate router.

Right I am convinced- NTL modem-ATA (either of Sipura 2100 or HT 486 will do) -homephone & wan coming off the ATA

Thx Aaron & bhickey for the advice
