Re: [asterisk-users] I can hear my own voice through the headset
Sorry for my last post, Here is my IP-PBX setupmy setup is : sips softphone - asterisk - xorcom PSTN gateway - pstn line to telcoi'm using xlite for windows when I make a phone call (sip - outgoing channel),I can hear my own voice so clear. it's very annoying mewhen talking a little loud... any solution? Two questions: (1) Does the problem occur when you make a SIP-to-SIP call, without the PSTN being involved? No, it's happened only when I make a call from sip to pstn line. (2) When you hear your own voice in the headset, is it delayed, or is just an immediate louder-than-you-want side-tone? it's immediate voice and very clear, just like talk-to-my-ear with no delay If it *does* occur in SIP-to-SIP calls, this would rule out your XORCOM and the PSTN as the cause. If it's only occurring in SIP-to-PSTN calls, then the XORCOM and PSTN (or the interaction between them) is a likely suspect. There are several things which can cause this sort of problem. (A) Direct acoustic feedback within the headset. In this case, you'd probably hear it even if the headset was unplugged entirely. The only cure is to buy a better headset. (B) Incorrect audio-mixer settings in your PC. To the PC audio infrastructure, a headset usually looks like a microphone and a separate speaker. The audio mixer (hardware and software) usually has an ability to mix some of what the microphone hears into the speaker output. If this knob is turned up too high, you'll hear your own voice too loudly. If too low, you won't hear your own voice at all when you speak into the headset, and many people find this lack of side-tone to be confusing. The cure here is to adjust the audio side-tone level, either in your Windows audio-mixer control panel, or in X-Lite (if it has such an adjustment). (C) Electrical reflection from an analog impedance discontinuity in the analog telephone-line system. This can result from a mismatch between the telephone wiring, and the PSTN interface device, and can occur at any point in the analog transmission. If the loud side-tone you hear is *not* delayed noticeably, then the impedance mismatch might be at your XORCOM/PSTN interface. The XORCOM may have a software adjustment or jumper setting, to match its audio impedance to that of your local phone line... try fiddling with these settings to see if they reduce the excessive side-tone level. If the loud side-tone you hear is delayed (it sounds a bit like an echo) then it may very well be at the far end of the phone line, outside of your own physical control... it might be at your local phone office, or anywhere between you and the far end of the phone connection. Not much you can do about this. (D) Audio feedback at the far end of the call, in a cheap phone handset. Sometimes, audio from the back side of the speaker in a handset travels through the body of the handset and is picked up by the microphone, and results in an audible delayed echo of the voice from the far end of the line. Using a better handset, or stuffing the handset full of audio damping material (cloth or cotton or fiberglass) is the cure here. Well, thanks a lot Lee for suggestion and explanation, I'll try this tommorow. We've often faced this problem with SIP soft phones when the computer's sound system gain was set too high. You usually have to play around with microphone gain settings to get to the point where the echo disappears with the other party still being able to hear you. And thanks for your share Raj, I appreciate that.. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
