Re: [Asterisk-Users] echo paid support
Thanks guys, The echo is there when T1 is connected directly to Asterisk box. If connected to TNT first then to Asterisk via SIP, then Asterisk echo training kicks in (you can hear it 1st second or so) then only a little. I haven't tried the steps below, but will when I build another box this next week.

I am using a Dell Optiplex GX280 with a P4 3.2GHz processor and 512MB RAM and Asterisk version stable 1.07. Here's what I came up with after reading many of the posts and much trial and error. 1. Make sure that ther is no GUI loaded on the asterisk box. 2. Recompile Zaptel with MMX enabled (I think this applies to Intel Processors only, but someone may correct me if I'm wrong.) To enable MMX in zaptel, before you compile zaptel, uncomment the line in /usr/src/zaptel/zconfig.h file that says: /* #define CONFIG_ZAPTEL_MMX */ and change it to: #define CONFIG_ZAPTEL_MMX 3. Recompile Zaptel with the Aggressive Suppressor enabled. I have never read anything about this, but saw it while I was enabling the MMX support. From reading zconfig.h, there are different versions of the echo canceller, but the comments say that the aggressive suppressor works with MARK2 which is what was enabled by default in stable 1.07. To enable the MARK2 AGGRESSIVE SUPPRESSOR in zaptel, before you compile zaptel, uncomment the line in /usr/src/zaptel/zconfig.h file that says: /* #define AGGRESSIVE_SUPPRESSOR */ and change it to: #define AGGRESSIVE_SUPPRESSOR 4. Recompile Zaptel with the instructions reordered. I don't know what this does, but it was recommended in these posts for fixing echo. To reorder the instructions in zaptel, before you compile zaptel, add the following in /usr/src/zaptel/Makefile underneath the comment in the Makefile talking about all the config settings being in zconfig.h. From the looks of it, it might only effect Pentium 4s??? CFLAGS+=-march=pentium4 5. Make sure the Zaptel card is not sharing an IRQ with othe hardware. In my case, this involved moving my T100P to another slot and disabling all USB ports. (I login remotely to administer the asterisk box since the GX280 doesn't have a PS/2 keyboard port.) 6. Make sure that you have a sufficient processor and sufficient RAM. I didn't make any additions to my configuration, but I did remove one 256MB RAM chip that seemed to be bad leaving 256MB. Hope this helps. Again, most of this is not from me, but others here with much more knowledge.
