asterisk 1.4.35 dahdi 2.3.0.1+2.3.0 one span on a 4port T1 card Got complaints this morning that outbound and inbound calls were "scratchy" and I made a few test calls. It kind of sounds like the gain is too high somewhere, and the audio is overdriven. Is this a problem at the carrier? I'm trying to call them now, but it's Sunday morning in the sticks, and my chances of getting someone with a clue are slim to none. I restarted dahdi but that had no effect. I watched dahdi_tool as calls came in and out but there isn't really a l...

...ten enough to be nasty. Call comes in FXO, * calls my home via IAX2... times out so picks up another FXO port and dials my cell. 7 times out of 10 it bridges just fine, but about 30% of the time I will answer and whenever I talk on the cell I get back a "buzz" (almost sounds like an overdriven dialtone) for the length of time I talk. e.g. if I say "Hello?" I hear that overdriven dialtone back at me about 0.5s later for the duration that it takes me to say "Hello?" The louder I speak the louder the return "buzz". Nothing unusual in the log (I get the od...

...encoder and would like some input. I use SpacialAudio's SAM3 Broadcaster and am having problems with the ogg encoder when I create a mono output stream. It seems as if the signal level of the left and right sides are being combined before the encoding process, leaving the sound muddy and overdriven. As such, if I reduce the output level by 6db, the combined streams are at the right level. The settings I'm using are Quality -1, 32kbps/44kHz. SpacialAudio suggested that they are passing the audio info to the library as required. Ideas? -I

...n feed it from WinAMP on my PC and listen to the stream somewhere else and it sounds fine. I know liveice is working too because Icecast shows that it connects and is sending audio to it. However when I listen to the stream on my PC with WinAMP it's aweful. It sounds like the audio is really overdriven, very distorted, grinding noise. In fact I can't even hear anything of the stream, just the grinding buzzing, and it is very loud. I'm feeding to the line in on my sound card from a portable radio. I get the same effect though whether the audio is plugged into the sound card or not. I i...

...voicemail system. Even stranger to me, is the fact that from the phone connected to the FXS on the wellgate I can hear tones(listening on a called line), but they sound kind "rough" at the edges. From the AG168V I hear no tones, but what seems to be "blown out" tones (ie overdriven volume). From the IAX softphones I hear no tones at all just clicks! Now I would have guessed that the FXO would be doing the conversion of the RFC2833 to inband, so that I thought all the tones should sound the same from any phone? Apparently this isn't the case at all. Thanks to all o...

...hone out) and I can run the AD1836 audio codec on 48 kHz only, I cannot use my program now (because I use speex resampling...) So I tried to do file I/O, but the described problem (that the encoder corrupts its input buffer) is gone in this configuration. But nevertheless, when I try to encode an overdriven (saturated) signal, the strange toggling between -MAX and MAX values on a sample-by-sample basis still happens. The debug output for this is as follows: SHL16: output is not short: 36500 in ltp.c: line 649 EXTRACT16: input is not short: 33074 in nb_celp.c: line 802 EXTRACT16: input is not short: 3...

...phone to talk, you get an over-amplified echo. The sequence is like this: exten => s,1,Answer exten => s,2,Wait(2) exten => s,3,Dial(SIP/201&SIP/202&SIP/203&SIP/204&SIP/205&SIP/206&SIP/207) If you let it ring for a while before picking up, you get the horrible overdriven echo. It's like putting a really large value for rxgain, except that the volume goes down as the echo is trained out. Has anyone else noticed this? -- Seth "cave quid dicis, quando, et cui" Mattinen sethm@rollernet.us

Hi everyone I wondered if any of you knew of a good PHP script to administrate Icecast, as I'm not satisfied with the webadmin interface (templates do not control everything and I'd rather not modify the sources). I've tried phpcast (found on freshmeat) but I'd like to see others in action. Another thing, anyone tried to change the mysql backend of icedir from SQL to LDAP ?

Hey, all. We're rolling out VoIP, and I'm wondering about PoE recommendations, as we're going to have to replace our current network equipment. My first inclination would be to just plunk down the cash and do a Cisco system, but I'm relatively certain that would get shot down by finance. Any recommendations for a couple-hundred-port solution with VLANs, PoE, and QoS? Don't
