similar to: Disabling echo cancellation by software

Hello, After installing on Ubuntu 10.04 using the tutorial on http://hmontoliu.blogspot.com/2010/03/installing-asterisk-and-freepbx-on.html I have a running instance of Asterisk. PROBLEM: result of dahdi_cfg: DAHDI Tools Version - 2.2.1 DAHDI Version: 2.2.1 Echo Canceller(s): MG2 Configuration ====================== Channel map: Channel 01: FXS Kewlstart (Default) (Echo Canceler: mg2)

My TE411p does not seem to like to have two PRIs from different telcos (span 1 and span 2). I can get one working, but not the other. However, if I use vpmsupport=0 when loading the wct4xxp module, they both work. But here is the problem, vpmsupport=0 disables the on board echo cancellation. Any ideas? BTW, here is zaptel.conf span=1,1,0,esf,b8zs span=2,2,0,esf,b8zs bchan=1-23 dchan=24

Does anyone know how to disable the VPM in software rather than removing the card altogether? The canceler isn't working as well as the software cancelers were. Aaron

Hi All; To overcome the echo problem, what mainly I have to do in the configuration other than the following line in the system.conf under dahdi directory? echocanceller=mg2,1-16 1) How can I know if the digium card supporting echo cancellator? 2) If I am getting a message in the consol that unable to enable the echo cancelator, then what does it means? The hardware is not supporting echo

Hi Asterisk Users, We've been experiencing some tough time regarding a new Asterisk installation connected to the PSTN via an ISDN PRI with a Digium TE121 with the optional VPMADT032 echo cancellation module. For now, I'll focus on something very specific which is summarized on this email's subject. However, here are some general facts for the context: - System pbxfri went

Hello All, I have 2 Digium card configure on Single machine, which can't share interrupt across all CPUs and sometimes asterisk reach 100% CPU usage. Here is system details and /proc/interrupt o/p.

Is there any known reason that the DISA() routine should behave differently than WaitExten() as far as recognizing DTMF tones? If not, I suspect there's a bug here. Try it yourself--two DID's on our PRI, numbers below let you test each routine: It is my observation that some setups/phones DO and some DO NOT express this variance. --I could not show any variance on a sprint mobile phone

Running Asterisk 1.6.2.9, DAHDI 2.3.0.1, CentOS 5.5 (update to date as of a week ago), I've installed a Digium AEX800P with 2 X400M FXO Modules and 1 VPMADT032 Module, hooked up to 5 analog lines.

I just installed a TE820 octal span T1 card, and it's not showing up in dahdi_hardware output. This was installed into a test machine that already has a TDM800P card in it, and that one is showing up and working fine. Is there some kernel module that I'm missing?

Hello I've got small PBX (30 simultaneous connections) based on asterisk (1.6.2.6), which uses Stargate 2N ISDN to GSM gate.

In what scenarios non-Echo Cancellation cards (T1/E1/FXO) should be used ? Don't all good and professional installations need echo cancellation cards?
