| 887516 | 2010-05-24 00:28:00 | So, quick question here: Is Dial-Up full duplex? I've heard a lot of "No, it's not", but I've also heard that the V.90 specification says it should be 56.6kbps down and 33.6kbps upload, but what it doesn't say is if that's concurrently or not. So, is Dial-Up full duplex, or half duplex? :) This stems from a client who's in Samoa who has unlimited Dial-Up and wants to make international tolls. If they're using something like a g729 SIP call, I'm wondering if this would be possible, even if low quality with a bit of latency ... Cheers Chill. |

| 887517 | 2010-05-24 04:23:00 | Sounds like a terrible idea. But here: www.kormanworld.net/telecom/3COMV90wp.pdf Assymetric is what I'd say.... |
