E-mail, chat, & VoIP : voice over ip
voice over ip
by Saphrar - 2/13/05 9:36 AMI recently started using at&t for voip. I have comcast as my cable and internet provider. When I make or receive calls I get a lot of interference, and have to ask the person I am talking to repeat themselves many times. I am using a noise filter. Any sugestions as to how I can corect this?

Skype...
by johnhighway - 2/13/05 1:13 PM In reply to: Skype by auggiefIt's my understanding that in order for you to use Skype for VOIP, the party on the other end must also use Skype.
Skype offers an option where you can call others that don't have skype, but you'll need to pay for this service.

by auggief - 2/13/05 2:15 PM In reply to: Skype... by johnhighwayYou're right. It is necessary to get the others on Skype also or you pay. If they are on Skype it is free internationally. All I can say is that it is really clear.
RE: This isn't what the topic is about
by Short Circuit - 2/19/05 3:51 PM In reply to: This isn't what the topic is about. by Tman1That is not entirely correct. SKYPE uses a SIP User Agent in an integrated softphone that connects to a networked Proxy Server just like AT&T, Vonage, Packet8 or any other VoIP service. Skype IS Voice over Internet Protocol which uses a SIP Invite method and an imbedded SDP (Session Description Protocol)message.
Calls "off the net" are routed to a PSTN Gateway, although only outbound calls are currently available. The main difference between Skype and AT&T is that AT&T offer an E.164 address (phone number)dedicated to a specified Gateway. This can be good or bad depending on your point of view. The main difference is you can receive calls from PSTN phones. (If thats good or bad is up to you). The problem is that you are still tied to one point on the map as far as calculating long distance goes.
An advantage of a system like Skype is that it uses a "soft" Gateway position. In other words, depending on which number you dial, the Proxy Server can redirect the call to the closest gateway to the destination - meaning less long distance charges.
All VoIP User Agents should be able to call net to net for free. It doesn't matter if you dial a phone number or a URI - it all goes to a Proxy Server to look up a destinatin IP address. Bottom line - E.164 assignments on VoIP User Agents are fake. Just because you don't get inbound calls from off the net doesn't mean it isn't VoIP.
Look at it this way - Once VoIP replaces the PSTN, no one will need Gateways anymore so SKYPE is just a little ahead of it's time.
Again, this has nothing to do with the topic.
by Tman1 - 2/20/05 1:42 AM In reply to: RE: This isn't what the topic is about by Short CircuitThe question was regarding REAL VoIP service as in using normal telephone equipment, not a PC.
I'm not sure how Skype got brought up. While you can use skype to call real #s like dialpad, it isn't free and you can't use a normal phone to place the call.
Skype IN and Skype OUT
by KaiStakka - 10/14/05 9:22 AM In reply to: Skype... by johnhighwayHey, folks, Skype is FREE!!! And it works great. And I've used it again and again from all over the country. It's FREE! Great sound quality.
So you pay a little more than 2 cents a minute if you have to call "skype" someone who isn't on skype and that's anywhere in the whole world! What's wrong with that? Isn't that cheaper than paying Vonage $20 a month and buying some extra equipment? I can skype from my laptop (for privacy's sake, I use a headset mike) and I'm instantly calling a contact. And you can set up a special phone number (with any area code you'd like) so that non-skypers can call you. Try and get better than that.

Vonage with no Wireless router
by rodesss - 2/15/05 3:25 PM In reply to: voice over ip by SaphrarSaphrar:
I use Vonage and had some interference as well. Though I talked to tech support a few times, I finally decided to disconnect my wireless broadband router. It was hooked up between my Cable modem, and my Vonage router. Since I disconnected it I have had NO interference. I don't know how it was interfering, I only know that since I don't have it connected anymore, I don't have a problem.
TA

Vonage with not Wireless
by carcus - 2/19/05 5:53 AM In reply to: Vonage with no Wireless router by rodesssOh joy...not what I wanted to hear!!
I have Vonage and have a wireless router between the comcast modem and Vonage router. I have the wireless router because we're a family of geeks (3 laptops, 2 pc's) and the house isn't hardwired.
I had a Netgear router that was CONSTANTLY dropping everyone, especially when I was dialed into work on a VPN. 5 or 6 resets a day were common. So my work gave me a Linksys wireless routers. Good news is that I've been able to remain connected to work throughout the night when on call. I sent a email to Netgear and two weeks later I got a reply: change your channel on the router and we're closing your ticket. Yeesh..some support!!
Bad news is poor reception on the phone. I lowered the quality setting on the Vonage web site, but might just shut everything on the network down, reboot the modem and then power up the routers and see what happens.
File sharing?
by Tman1 - 2/15/05 10:06 PM In reply to: voice over ip by SaphrarIf you are uploading anything while using the phone, it will break up, especially if you have the TA behind a router.
If the TA is before the router, then you shouldnt have any problems, since the TA takes the bandwidth it needs. Web surfing slows noticeable while using the phone set up this way.
TA configuration
by droy99 - 2/19/05 7:42 AM In reply to: File sharing? by Tman1I was just browsing through and saw your explanmation for putting the TA before the router. I just signed up for SunRocket, that is the way they recommend the TA be wired.
However, most of my friends who have either CallVantage or Vonage were told they had to have a router to use VOIP. They have it configured like modem, router and then TA. But, what you say makes cents.
There is probably more to it than that, because, if not, why would they recommend that people put the router first. When I get my TA from SunRocket, I will wire it up the way they recommend and see what happens. I am going to keep my existing phone service for a few weeks. If I have a lot of trouble, I will simply send the TA back to Sunrocket.
Using Sun Rocket
by bluer - 2/19/05 6:51 PM In reply to: TA configuration by droy99I've been trying Sun Rocket for several weeks. My main problem so far is intermittent echo from my end. (Of course the voice quality is not equivalent to POTS but it seems usable.) I have it set up as modem-TA-router-PCs. The echo is intermittent and may occur with concurrent PC use - don't know. I'm interested in any data or results anyone might have.
