I can hear callers on my phone fine, but many different people I call say I am breaking up, delay in voice, echo, or they hear feedback. Does anyone else have this problem? It doesn't matter where I am calling from.
Bring the phone into your carrier and ask them to check it out - it sounds like an echo suppressor problem, and that's part of their equipment. ("Breaking up" doesn't happen in digital communications, you "go digital" - either sound like you're underwater or like you're super autotuned, depending on the carrier. Breaking up would be somewhere the signal is analog and, aside from your mike and a few components on your motherboard, that would be in your carrier's equipment.)
