RE: [Asterisk-Users] X100P Echo Problems..What's going to happen?

John: I don't use MSN so I can't comment.  I do know that when my connections are pure VoIP (no analog PSTN connections), the quality is better if enough bandwidth is available. TCP is a protocol that gets used when you want to make sure a packet arrives at the other end.  UDP is better for voice because you don't want packets to be retransmitted and have to wait to assemble them on the other end in sequence so the conversation makes sense.

What I don’t understand is why MSN messenger is perfect with no echo?  I switch back and forth and still hear a big difference.  I believe MSN is using TCP rather than UDP.  Can * run on TCP rather than UDP?  I think this makes senses and can eliminate that echo.   -----Original Message----- From: Uriel Carrasquilla [mailto:[EMAIL PROTECTED] Sent: Monday, October 13, 2003 10:02 PM To: [EMAIL PROTECTED] Subject: RE: [Asterisk-Users] X100P Echo Problems..What's going to happen?   John: I have been around voice over data packets for quite a few years and I am still to see the perfect system that works identical to circuit switching 100% of the time.  My opinion is that there is a lot more to the story than just parameters.  Packet loses, double compressions, faulty routers, bandwidth, analog to digital and so on can get in the way. On the other hand, if your customer understand the benefits, and I mean more than cost, and can leave with 80% perfect, then you will be able to understand why a lot of companies have opted for VoIP (or ATM or Frame Relay).

Importance: High I’ve read and experienced the echo problems with the X100P.  Is Digium going to fix the problem or refund our money?  I want to see this work because myself and other small companies out there use analog lines.  I would trade up to T1 but that requires me to have at least 9 lines.  If I did trade up, do the T1 cards work perfectly with no echo at all?  I get echo with my directly connected computer using Xten SIP.  No matter with all the suggestions to change the parameters, it still has echo.   Does anyone have the T1 and have no problems at all?  I would surely appreciate you experiences.  What’s my option to get this too work flawlessly?   John
