ADPCM - vs - G.726
I have been looking at the medium-rate codecs in Asterisk - ADPCM and G.726. Both of these are adaptive PCM codecs - the G.726 one is a little more expensive in processing power, however both are 32k bit-rate. I am experiencing problems using G.726 where the audio level is high. It produces loud clicks as if clipping. For quiet audio however, it seems fine. ADPCM (Digilogic VOX?) seems to be

Adpcm, 6KHz codec
Is there a way to play adpcm, 6KHz in asterisk? If yes, where can we get this codec? Thank you. Alex Zarubin -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20030916/b8be2453/attachment.htm

Play file from an offset
I am projecting to migrate applications written with the Dialogic API to Asterisk. There are a few things that I do with Dialogic that I am still not sure are possible with Asterisk : - play a file from an offset (so a user can press a key to rewind 3 sec., pause, etc.) - dynamic volume control (the user can press a key to increase or decrease the volume) Thanks if anyone has a clue...

ADPCM codec and IAXy device
Hi All; I need to buy one IAXy device, but I discovered that it supports only g711 and ADPCM codec, so I was wonder that it does not support g729 or GSM?! Anyway, what is that ADPCM and how much it consumes bandwitdh? Also, asterisk support such codec? What its name in the configuration? Any advise? Regards Bilal

RTP/RTSP streaming of GSM or ADPCM audio
Greetings: It would be nice if Icecast supported RTSP; however I would appreciate any suggestions for a small RTSP/RTP solution to encode 8kHz mono audio in GSM or ADPCM and service multiple unicast client connections. The ideal would be a black-box hardware solution with an audio input and ethernet interface similar to broadcast studio IP audio links or the network audio capabilities of certain

IAXy and ADPCM codec problem
Hi everyone, I'm using the IAXy boxes and i'm having some trouble when I use it with the ADPCM codec. When I use the ADPCM codec only one person (out of the two of the conversation) is able to hear the other, but when I switch to ULAW codec everybody can hear the other. The ULAW codec is too heavy for my bandwidth (64Kbits/s) and its sounds choppy, the ADPCM codec sounds good but only

samba bad password count reset between logins (not loaded from login_cache.tdb)
I found out the answer to why the bad password count was failing by following the stack trace If anyone has the same problem, this was caused by my access rights being too restrictive. source/passdb/Init_sam_from_ldap.c:1064 => There is a "goto fn_exit;" in case ldapsam_get_entry_timestamp() fails before the cache is read via login_cache_read. This function will fail if it cannot

ADPCM support with RECORD FILE
I want to record audio in ADPCM format. According to the "show codecs" output of Asterisk, it looks like it supports adpcm. But I do not know what to tell the "RECORD FILE" directive in my AGI script. The RECORD FILE command usually has this form: RECORD FILE <filename> <format> <timeout> [BEEP] It records fine in WAV or GSM if I enter "wav" or

Asterisk dimensioning (IVR, mass calling)

Here is the general description of the traffic in question : - IVR system, 138 PRI channels (6 PRIs, multiple D-channel) - Some traffic from TV ads, so all traffic typically arrives within a few seconds - Up to 12-15 simul. outbound (external) conferencing calls for

Background Noise Elimination
Greetings! We have a somewhat noisy background in our call center, and I'd like to reduce this. Obviously, we could plaster the walls with sound absorbing material, but is there anything we can do in software either using any algorithms for our open source-based SIP library or inside Asterisk itself? Related to this, anyone have a good source for good panels? We are using
