Using TDM400's here and I have tried everything to cure the echo. I have used the Milliwatt test from the telco and from asterisk to tune RX/TX gain via a patched ztmonitor. What happens is I experience midcall echo. I turned on aggressive_suppressor and it seems to do great. The problem happens with misc. noise around the office will cause it to mute the other end of a phone call while they are talking. I haven't been able to find anywhere in the MEC2 source to limit when it mutes the remote party. It seems to do it with just the slight...

...clicks that I had assumed were a result of this. So, I ordered a TDM400P with 4 FXO modules and installed it in the box last night. Today, we've had nothing but problems with it dropping calls. I installed the latest CVS of everything, and we've been getting random hangups. If I disable AGGRESSIVE_SUPPRESSOR, the random hangups seem to stop but we of course experience *really* bad echo. I have busydetect=yes and busycount=8, which has previously been working just fine with the X100Ps. Does anyone have an idea what's going on or how to fix it?

...FXO module installed. I have tried a few things, such as: * setting rxgain and txgain to 0 * setting echocancelwhenbridged to no / yes * settting echocancel to 64 / no / yes * setting echocanceltraining to 800 / no / yes * MG2 echo cancellation * MARK2 echo cancellation * KB1 echo cancellation * AGGRESSIVE_SUPPRESSOR option of MARK2 Each time restarting Asterisk, then opening the Zap channel, and then speaking...only to hear my self played back almost instantly. None of these options changed the echo for me, it always sounded the same -- except for the AGGRESSIVE_SUPPRESSOR option, in which every time I spok...

Has anyone turned this on and then noticed that calls coming from queue's seem delayed? I.e. when a call rings an extension (or agent) that it says the call is connected, yet the call remains in the queue, and can take upto 20 seconds to be established with the agent. I have only noticed this when this is enabled in zconfig.h Has anyone else had a similar experience? Cheers,

...te party does not notice any difference. I have tried all the following. #define CONFIG_ZAPTEL_MMX <tried this defined and undefined> Then tried each of the following types of echo cancellations. #define ECHO_CAN_MARK #define ECHO_CAN_MARK2 with and without #define AGGRESSIVE_SUPPRESSOR #define ECHO_CAN_MARK3 I am completely at a loss on how to get rid of this echo problem. The system is completely useless for incoming calls, as it currently stands. Is there a Digium card that handles echo better? Are there any asterisk compatible cards with hardware echo cancellation avai...

...hone calls. Is this a sound theory? If so, perhaps there are some common telecommunications devices or wiring practices that are used in modern high-rise buildings that may be causing the problem? Any advice on how to troubleshoot this? Thanks in advance Ryan ps: I've yet to try defining AGGRESSIVE_SUPPRESSOR in the zaptel source. Is this recommended?

...permicro, but it was still there. There is NO echo on the DL380 We are currently testing the Compaq 6400R for compatability and will let the list know how it goes.

Hello, Can the wildcard x100P be bought of the shelf in stores - say in Singapore. Thanks Varun

Hi, I'm thinking of purchasing a TDM400P card and was wondering if anyone has experienced any echo issues with phones off these cards connecting to the PSTN via the X100P cards? I have had my fingers burnt with a Voip phone > X100P. Cheers, Taff. --------------------------------- ALL-NEW Yahoo!

I have a 12 channel PRI with SNOM 190's and asterisk CVS from January. Most calls are fine, all incoming calls are fine, but I am getting echo on a significant number of outgoing calls. The person on the other side hears a perfect call, but the SIPphone side gets to hear themselves. It happens 100% of the time to some numbers (outgoing only), and only sporadically to others. Has anyone

I am using a SIP softphone (X-lite, SIPPS or Firefly) connected to an Asterisk v 1.0.3 PBX. The PBX is also connected via a ISDN-PRI crossover cable to a Avaya Definity Generic 3 PBX via a TE405P card. All outside of the office calls go through the Definity. Here's the issue: Calls to internal SIP extensions, Definity extensions, other offices within our private network (through the
