Well right. The analog portions of most calls are extremely small anymore (speaker to ear and mouth to microphone). ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com ----- Original Message ----- From: "Carlos Alvarez" <caalvarez at gmail.com> To: voiceops at voiceops.org Sent: Monday, June 14, 2021 4:31:07 PM Subject: Re: [VoiceOps] Call Quality Well, no call is purely digital, the endpoints are still analog, as is the meatbag behind the handset. I can't imagine any way you can create echo in the digital portions. But a mismatch in impedance on an ATA or similar device would be a common old problem I've faced.

How are these quality issues introduced? As long as pipes and equipment aren't overloaded, where is a quality issue to come from? Obviously, the closer you are to the handsets, the less opportunity there is for issues. What else is there to take into account? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops
