Linksys VoIP boxes NOT tied to a particular provider?

Question

If you look in the Linksys pages, you will find that they only offer two devices which combine NAT routing and SIP telephony, for domestic use:

1) PAP2: This seems to be a Sipura (now Linksys). In the manual they refer exclusively to Vonage. In my experience the Sipura boxes don't have the capacity to drive a LAN, as their NAT capabilities are lacking and the most you can connect to them is ONE PC (in the PC port). Sometimes not even one connected PC will work, because as soon as you connect it, the audio will become impossible to understand.

2) RT41P2-AT: This is a much more capable device, combining the NAT abilities of a Linksys product with the SIP abilities of a Sipura. Looks like it should fill my needs. EXCEPT that this product only works in conjunction with the AT&T CallVantage service.

So, it looks like the folks at Sipura/Linksys/Cisco believe that if you want to experience IP telephony from your home, you have to sign with AT&T.

Isn't there a RT41P2-NA??

Technical note: I have assembled a SIP network with about a dozen ATAs in 4 countries, and have seen all kinds of NATs, etc.

> Well I hope the RT41P2 is better implemented than the RT31P2.I had nothing but grief with that box whenever the LAN/WAN portswere heavily loaded (hanging & self-rebooting).  I suspect a verybadly implemented NAT which can't handle a large number ofconnections.I finally convinced Vonage to swap it out for an RTP-300 whichis more stable under heavy load but doesn't seem to implementany QoS/priority for the voice stream. Under heavy load youcan't even originate or receive a call and although the RTP-300doesn't crash or hang, you can forget about making/receivingphone calls while running a bit-torrent for example.Overall I'm very disappointed with the Linksys products I'vetried, they are certainly not what I've come to expect from aproduct with the name Cisco on the box.Norm

[Norm Young:]Well, you have to keep in mind that the NAT devices we are talkingabout are designed for *domestic* networks, with only a handful PCs.If I am connecting an office, I would use a real Cisco router.-Ramon
