about bluetooth channel
28th February I am working with Asterisk 1.2.15. I have configured sip.conf for two soft phones (I am using Xlite).I have installed the Bluez stack and so far, i manage to make a phone call from a soft phone to a GSM network. However, i have an audio problem. The soft phone can be heart by the GSM costumer but the voice in Xlite is not transmitted to the GSM. In asterisk all i got is the

OT: real 2 line phone vs. 1 line and call waiting
I'm looking into getting a new phone and wondering what the difference in functionality is between a single line phone with call waiting and a real 2 line phone (either a real SIP phone or an analog 2 line phone and a 2 port ATA) is. Why would I want the real 2 lines vs. just being able to take an incoming call via call-waiting? Cheers, b. -------------- next part -------------- A non-text

echo cancellation
Hi! I want to use speex for echo cancellation in my program, but I have bad results. I will explain what my program does. it is a client-server application. I run a server in room A and a client in room B. the client sends some voice to the server and the server plays it on loudspeakers. I run another server in room B and connects to it from room A using the same application that runs

Really, really loud ringers
Anyone have some recommended equipment for alerting people to calls in a noisy environment? I have Polycom IP550 phones set up in some really noisy environments - our mine hoists - and they tend to drown out the ringers. I'm using Clarity WR100s now. They're analog devices, attached to Linksys PAP2T ATAs as part of a call group to get a loud (advertised as 95dB) ring out there, but it

Can compressed music sound better than uncompressed?
I quote from "Principles of Digital Audio" by Ken C. Pohlmann: "Because perceptual coders tailor the coded signal to the ear's acuity, they similarly tailor the required response of the playback system itself. Live music does not pass through amplifiers and loudspeakers, it goes directly to the ear. But recorded music must pass through the playback signal chain. Much of the

R: echo cancellation
Hi, Indeed I too have troubles implementing echo removal, I like ask kindly to Jean-Marc (or any other) if him can put a source code demo to show us how to use effectively echo removal API and parameters in real case scenario.

trouble getting speex_echo_cancel() to work
I'm trying to convert my current headphones and microphone chat application to support loudspeakers and microphone, and so I thought I'd give speex_echo_cancel() a try. Since my users quite frequently have other sound-producing applications running on their computer (such as winamp), I sample 'wave' recording device of the soundcard in addition to the microphone. I then call

Problem accessing files on mounted .iso?
Hi everyone! I'm a Linux newbie (running Ubuntu Edgy), and even newer to Wine, but anyhow ... My problem is the following: I've been trying to start up an old Win 95 game -- Curse of Monkey Island 3, if you remember it -- and have the two CDs on my hard drive as .iso image files. So, I mount the first CD to make it accessible, and then add it as drive d: in the dosdevices folder. All

problems with echo cancellation filter
Hi! there are some problems with echo cancellation filter from speex. problem 1: some noises, echo is removed, but sometimes you can hear some noises instead of echo. I was trying with many different parameters for buffer length (40ms and 20ms), filter length (from 100ms to 4s) and echo tail (2 to 5 buffers), but could not find the right setting. problem 2: it happens that the filter

speex_echo_cancel, please help!
Hello, Need some help using the speex_echo_cancel. I've read the documentation about the speex_echo_cancellation function: speex_echo_cancellation(echo_state, input_frame, echo_frame, output_frame); (in) echo_state => speex internal state. (in) input_frame => audio captured by mic. (in) echo_frame => the signal that was played in the speaker. (out) output_frame => the

original audio the best audio?
I was just wondering if the original audio is always the best audio. I'm sure every compression format including vorbis is based on trying to make the output sound the closest to the listener to the input. I was wondering if there is any possibility that there would be a way of modifying the huffman tables or something in some way to make the output sound better than the original? ---

OT: good headphones?
This is off-topic, mostly, but I figure you guys will have some knowledge in this sound-quality-related area. I'm sitting here looking at the most recent "Musician's Friend" at headphones and thinking about getting a pair. They've got products from AKG, Fostex, Audio Technica, Nady, Sennheiser, and Sony, at price points ranging from $16 to $130 (list prices $20 to

large scale paging
Has anyone done any large scale intercom deployments with Asterisk? I've been asked about building a system to one-way page 500 phones simultaneously from a single server. My concerns are: - My limited math capabilities suggest 41 Mbps of RTP traffic, which seems like a lot, plus asterisk would be taking a single input stream and exploding it out to 500 endpoints. - There are 500
