Hi there, i called one asterisk server from another asterisk server. The calling server played back a audio data und the answering server recorded the audio sample using record() function. I tried both ISDN, VoIP connections. Camparing with the original audio data, the recorded samples from both connections were amplified by asterisk, so that the recording were much louder. But I didn't

Hi, I am using Samba as a file server only; with no whatsoever printing service. Therefore I would like to get rid of the printer-icon when the users access the samba-server. How can I do that ?

Is anyboby using the areski CDR reporting tool? I have installed asterisk-stats v1.2 three days ago, but I found a possible bug in it. My calls compare graphic shows most of the on the calls at first hours past midnight, and it never logs anything after lunch time. This is wrong, my calls are made on business hours. The call log lists those calls at the right time. Is there

Hello, I sent a wav-audio to Asterisk though SIP and ISDN channels and recorded it in wav-audio at the Asterisk server. I found the loudness level of the recorded audio was too high comparing with the orginal audio. How can I ajust it, so that there will be no amplifier used for recording. Thanks a lot. best regards Felix -------------- next part -------------- An HTML attachment was

Dear colleagues, after hundreds of hours I finally managed to figure out how to send faxes from a T.38 capable endpoint reliably via Asterisk / PJSIP. My setup is as follows: A T.38 capable endpoint sends the fax to Asterisk which passes the fax to a T.38 capable trunk which then sends the fax to its final destination. This works great, but I have left a little problem which I couldn't solve

Hi, How would one activate/deactivate hardware echo cancellation on the TE406 card? Can it be done per channel? I'm going to run TE406 in the following scenario: ISDN -> TE406 -> PABX I understand from Steve Underwood's site that echo cancellation is not good for faxes (and they do that themselves). So what I want to do and bypass echo cancellation for selected extensions before

Hi all, 1. Just bought a new TE411P and about to install it replacing the existing TE410P. I am assuming I need to set echocancel=no and echocancelwhenbridged=no now that it will be done in hardware, correct? 2. Is there any way to monitor hardware echo cancellation to ensure it is working (apart from being on a call)? 3. The Digium webite says "By supporting 16ms with 128 channels or

Hello all, I use speex as codec [narrowband and wideband], echo canceller and preprocessor. I was able to use it in all case except in echo cancellation. I found that in my application, echo cancellation works only if echo tail [echo filter length] is arround 2000 ms or more. But recomended value in the documentation is 100 ms. With 2000 ms echo tail echo cancellation works fine but it takes

In what scenarios non-Echo Cancellation cards (T1/E1/FXO) should be used ? Don't all good and professional installations need echo cancellation cards? Are there people out there with non-Echo Cancellation cards for T1 or 8 FXO ports and who really don't have any echo issues and they are running serious businesses? -- Zeeshan A Zakaria -------------- next part -------------- An HTML

Dear, I have Asterisk 1.6 with an E1 Digium card with echo cancellation module. So I need to use just the echo cancellation by hardware and disable the echo cancellation by software. I use DAHDI for my telephony hardware. If the lines involved with echo cancel are: In /etc/dahdi/system.conf: echocanceller=mg2,1-15,17-31 In /etc/asterisk/chan_dahdi.conf: echocancel=yes echocancelwhenbridged=no

Shortly, I'll be purchasing a Sangoma A102. I'm wondering if I should spring for the hardware echo cancellation circuit or not. Upon initial implementation, the 2 T1 Ports will be used as a passthrough as we slowly transition off of a legacy PBX. Eventually, we'll only be using one of the ports, and will be providing VoIP service to a bunch of SIP deskphones. So - with that usage
