...old ones. The T1 type is 24-channel, D4/AMI SF Robbed-bit(the same as the T1s they replaced) The problem is that we are getting echo on about 10% of the calls in and out placed on these new T1s compared to less than 1% with echos on the old T1s. I was wondering if anyone with T1s or E1s is using echotraining=yes. All the info on echotraining I've found seems to involve POTS lines not T1s. Also, how much of a pause is made when using echotraining? Here are my current zapata.conf settings for the T1s: [channels] group=1 language=en signalling=em_w usecallerid=yes callerid=asreceived context=default...

Hi. I'm having problems with chan_mISDN configuration. Line "echotraining=yes" causes warning, when Asterisk is parsing misdn.conf and I'm confused why the PBX doesn't accept the setting. No matter which section I try to offer it, it is always invalid or out of range. The setting itself is supposed to be valid, it is in the sample configuration file of c...

...seems fine except for an echo on all calls on the local end of the call. In almost all cases the echo goes away after 15 to 20 seconds. I am attributing the echo going away to the echo cancellation code that was enabled when the following options are set: echocancel=yes ; echocancelwhenbridged=yes echotraining=yes ; Is there anyway short of playing with these options which I have already done to improve this echo issue. -------------- next part -------------- An HTML attachment was scrubbed...

...option & KFLAGS+=-DAGGRESSIVE_SUPPRESSOR is now gone. Does simply adding these options still compile in a certain echo can - or is there an other method of activating a particular can. I have not had to update my machine that is connected to pstn for a while & I don't want to jump into echotraining without a way to quickly enable what has been working for me. How do I enable this mode now?

Hello, I have a TDM400P with 4 FXO ports, currently using three. When sending or receiving calls on this card, there is a nearly constant popping/clicking sound, it is related to the echo cancellation?. I adjusted my gains properly, but to no avail. I even found that setting echotraining=no in zapata.conf didn't change the scenario at all. I've plugged analog handsets into the same jacks, and the line is crystal-clear. Below is my zapata.conf, if you guys have any ideas how I might resolve this, I'd appreciate it. I have installed from sources Asterisk 1.2.22 and z...

...1.2.1 (and zaptel 1.2.1) and a TDM2400P with echo canceller. I installed the card but no echo cancellation is being made...seems like the echo canceller module does not work, infact the software cancellation is working. My zapata.conf has echocancel = 128 and echocancelwhenbridged = yes but no echotraining parameter which gives a warning. I found no info about how to use this card and how to correctly set zapata.conf, which zaptel version to use, etc... Does anybody knows how to use this card? TIA Giorgio Incantalupo

I find that when asterisk answers the phone, the initial second or so is lost. I can imagine that echotraining can do this, but this is between SIP phones and I don't think there is any echotraining enabled? BTW. Asterisk is definitely playing sounds that first second (The CLI would indicate that it would play a beep but I just won't hear it). Any comments appreciated. Pieter
