In what scenarios non-Echo Cancellation cards (T1/E1/FXO) should be used ? Don't all good and professional installations need echo cancellation cards? Are there people out there with non-Echo Cancellation cards for T1 or 8 FXO ports and who really don't have any echo issues and they are running serious businesses? -- Zeeshan A Zakaria -------------- next part -------------- An HTML

Hey guys, Currently we have non HWEC sangoma pri card but now we are planing to replace card with HWEC support card for echo cancellation. So in this case do I need to re-install everything? Like zaptel, asterisk etc.. Or just replace the card? -- Sent from my iPhone

Hi, I have the following setup: Ubuntu 12.04.02 LTS (64 bit) Asterisk 11.2.1 Sangoma 4-Port-Card (A104d) with firmware 43 (german e1-ports connected) WANPIPE Release: 3.5.28 DAHDI Version: 2.6.1 Echo Canceller: HWEC libpri version: 1.4.12 I call via sip into the dialplan. Then I do a "Dial(DAHDI/g1/voicenumber,r)". The call is bridged and everything is fine. "dahdi show channels" shows me, that channel 1 is used for the outcall. Then I try to hangup the outcall via "dahdi destroy c...

...ross ship - really good support team there). But the client is of course chomping at the bit to get the system live. We are totally out of touch on the subject of software echo cancellation in asterisk. The system is running 1.4.28 and Dahdi 2.2.1-RC2. I understand that when Dahdi detects no HWEC, it enables SWEC by default. Is there anything I can do to tweak the settings to try and make this liveable for the client until we get the card? The server is in the Caribbean, so it may actually be a bit before the card arrives. We would love to get them running before then, but it is so ba...

Hi all, I was using dahdi 1.6.2.0.9 version for a long time. We decided to upgrade to 1.6.2.22 a few days ago. After that we started to have some problems with dahdi channels. PS:DAHDI Version: 2.6.0 Echo Canceller: HWEC, MG2 We have 2 PRIs between Ericsson pbx and asterisk and a sip trunk for outside calls.

I'm a long time user of Digium carts and stupid me i wanted to give Sangoma a try. We got Sangoma A400 with 6 FXO ports. Asterisk version: 1.4.35 Zaptel version: 1.4.11 Wanpipe version: 3.5.11 we tried to use fxtune but looks like it wont work with Sangoma card, ( please correct me if i'm wrong) Echo is really bad and also we have background noise on all lines. We tried both mg2 and

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?

Hey Guys! We had echo issue before so we replaced old PRI card with Sangoma A102D HWEC. Now my question is i set rx/txgain level 0.0 default do i need to touch this value or default is best. I have read on google and people say it should around 14844 on ztmonitor for rx/tx level same. I just use milliwatt and test my default 0.0 rx/tx level and it come around 4600. Do you think i...

Hi all, We need to get better echo cancellation on an Asterisk gateway. Currently it has two TE410P (1st gen) cards. So would it be possible to just buy two VPM450M cards ? Or do we need to buy two new TE412P cards ? In that case a Sangoma A108d card would be nice as well ? What configuration gives the best audio quality ? Thanks, Leon de Rooij leon at scarlet-internet.nl

Dear, I have Asterisk 1.6 with an E1 Digium card with echo cancellation module. So I need to use just the echo cancellation by hardware and disable the echo cancellation by software. I use DAHDI for my telephony hardware. If the lines involved with echo cancel are: In /etc/dahdi/system.conf: echocanceller=mg2,1-15,17-31 In /etc/asterisk/chan_dahdi.conf: echocancel=yes echocancelwhenbridged=no

the attached log with verbose=6 and debug=6 refers. we've got a sangoma A104 (no hwec) with PRI ports 1 & 3 loopbacked to each other. we're trying to have txfax send out on one of those pri ports with rxfax listening on the other side, hence having asterisk send a fax to itself. we however have bad, and i mean really bad (<10%) success rates. we're currently using as...

Internet Connection is an ADSL2, with a not so reliable ISP in australia. For incoming calls, I had a Digium TDM410P with 4xFXO modules and HWEC. Because of these problems, i replaced the Digium card with a Sangoma A200D, but it didn't make any difference to the problems. All phones are hooked up to a Netgear PoE switch.
