Vonage quality is decent, but it does fail from time to time, at least on my cable modem, which could be due to its limited upstream. I do hear echo from time to time, and detect longer than normal latency. During a Vonage to Vonage call with Bob Frankston, we had a few seconds of complete garble dropout and a number of clicks. Vonage uses a non-compressing codec that requires about 90kbits/sec of bandwidth in each direction, they say. 64kbits for the voice and some extra overhead. You can switch codecs (though they claim it may take an hour to kick in) to use a compressing 30kbit codec. However, while using that codec, several people on the other end reported to me they felt there was terrible voice quality, so I gave up on it. So I can't rate it as matching PSTN Toll Quality yet. The reason to get it is features, or if price is an issue for you, price. Thus it is ironic that Vonage has decided to go for a "look as much like POTS" approach as they can. They don't support, for example, letting people call you with SIP phones though there is no reason for them to disallow this. It would also let you use your computer to command your Vonage phone to call a SIP phone, also handy. This an other click to dial applications would be cool. They have had a lot of problems with their voice mail but say they are fixing them. Note however that using a hardware device to do your SIP conversion is a huge win. Many people reject VOIP because they tried a PC soft phone. Even though the PCs have lots of power, they just don't seem to do a good job in most of the applications that are out there. They add lots of latency right in the PC. So while I rated Vonage as not up to the quality of POTS, if POTS is a 5, Vonage is 4 to 4.5. Sometimes it's more than a 5, but you can't guarantee it. Which is worth it for the idea of getting away from the Bell System and the regulation and monopolies and the lower prices. One cool feature is call transfer, available only on incoming calls. If you call me on my vonage phone, I can flashhook and transfer your call to my cell phone, and get up and walk away. I can't transfer if I called you, though I can 3-way call. There are competitors to Vonage -- iConnectHere.com (a unit of DeltaThree) will also work with the Cisco ATA and other SIP Phones. They are much more flexible than Vonage, in that you can use soft phones, and you get to control your endpoint. Vonage locks up your Cisco ATA so that only they can configure it. While you can take your Vonage box on the road, which is handy, with iConnectHere and other more open services, you can keep the ATA at home and bring a lower quality "soft phone" with you on the road -- ie. just a headset that goes into your laptop. However, there is no question the soft phone quality is inferior, and I would rate it a 3.5 out of 5. I have not tried DeltaThree with the ATA (because Vonage owns my ATA and I can't try switching it to another provider) but I have heard it's reasonably good with one of those. Another competitor is 8x8, and their packet8.net service. Very attractive pricing and you won the equipment. But I have not yet tried them. If you _do_ want to sign up for Vonage, make sure to find another Vonage user and get them to do a referral for you. They send in your E-mail, and you click on the link in it. You get $40 credit on your account and so does the referrer. I don't believe you can get the $40 credit if you sign up on your own. BTW, Vonage has other plans. For example the $25/month plan includes 500 minutes of USA and Canada calling, and unlimited local. This may be a better deal than the $40 plan if your LD is more limited. If you average fewer than 13.3 hours of LD in a month it is a better deal. More competitors will be coming. With Windows Messenger (bundled only with XP), there is a decent SIP Softphone, which can be used with iConnectHere and several other providers. Those providers are moving into support of hardware such as the Cisco ATA and dedicated SIP phones. ------ End of Forwarded Message ------------------------------------- You are subscribed as interesting-people () lists elistx com To manage your subscription, go to http://v2.listbox.com/member/?listname=ip Archives at: http://www.interesting-people.org/archives/interesting-people/
