similar to: TE411P zapata.conf, monitoring echo cancellation and echo tail size

I just implemented a system using a TE411P hardware echo cancellation card. Per Digium, I setup zaptel.conf, and zapata.conf the same way as I always have. To my surprise calls out to the PSTN had a terrible echo. 1 - 2 second delay, and quite clear. The echo was so bad that I had to remove the hardware echo cancellation module from the card. We are only using the 1st span of this card right

Hi all We use pci/pci-e BRI cards in our installations. Due to echo problems (that was before Oslec and others), we quickly switched to cards with hardware-based EC. So we use exclusively Digium B410p cards that provide 64ms tail EC. For several reasons we'd like to switch to external BRI gateways like the Patton smartnodes (the price is getting really close to a B410p). I'm

I have seen conflicting references in regards to the Digium Wildcard TE411P echo settings in zapata.conf. Does anyone have the official word on this? Should echo cancel be enabled in zapata.conf if the card has built in EC? If so, should a particular EC method be compiled into the zaptel build? My reference, which has echo: My zaptel is 1.2.5 context=from-pstn switchtype=national

Hi, I found E400P quad PRI card quite cheap (749USD): http://www.govarion.com/product_info.php?cPath=1&products_id=2&osCsid=68cdd6e3d08754 in comparison to te410p (approx 1500 USD ) http://www.digium.com/index.php?menu=product_detail&category=hardware&product=TE410P Now newer generation with HW echo canceling emerged (te411p). I'm not sure in what things those two cards

Hi Guys, I need your recommendation which card to buy?The TE411P or TE406P do they have any difference?I check their brochures they are differ only when it comes to PCI slot voltages.Which card best to use?Btw,Il be using supermicro board with 3.3V and 5.5V?Will il be experiencing problem during the implementation later on if i choose the wrong PCI voltage options?Will it depends on

hi! anyone please recommend/guide me of purchasing a resonably high performance server system regarding processor(s) & motherboard (+ other compulsary peripherals i.e. VGA, Soundcard). Mentioning up-to-date vendor+model will be more helping I've to use Digium TE411p Quad E1 card signalling on the E1 is SS7 no. of simultaneouse calls is 100+ regards -------------- next part

I am getting ready to purchase my first Digium card to start experimenting with Asterisk. Before I make my purchase, I wanted to make sure I'm not going to have issues with these cards (need to see what the specs are on my box, 5V or 3.3V PCI ). I will be using Asterisk @ Home, so will be Asterisk v1.0.9. I took a quick poke at the lists, and it appears several people have been having

Hi all, I replaced a TE410P Rev C 1st Generation Firmware with a TE411P without any cfg changes (zaptel/zapata). As a result Asterisk crashes on outbound from PRI4 going to PRI1 calls: Aug 23 18:22:00 WARNING[4693]: chan_zap.c:7545 zt_pri_error: PRI: !! Got a UA, but i'm in state 1 Aug 23 18:22:00 WARNING[4693]: chan_zap.c:7545 zt_pri_error: PRI: !! Got a UA, but i'm in state 1

Dear all, Does anyone try to install 2 or multiple TE411 card into one server? Can it be done? What about stability?

The Orion echo canceller is just ok. The Tellabs units work just as well if you don't mind 10 mins of soldering. I have the orion running with an adit 600 and a TE110P. Echo cancel is fairly good, but I have loads of problems with DTMF digits. -Darren ________________________________ From: asterisk-users-bounces@lists.digium.com

I checked the list of what not to use, but am still having no fun trying to find a working box. Can someone suggest a Compaq or Dell or MPC or . any other brand and model that is known to work well with the TE411P ? Will an old Proliant do? -------------- next part -------------- An HTML attachment was scrubbed... URL:

I changed from a TE410P to a TE411P and fax carriers weren't detected anymore ! I have tried everything (recompile zaptel+asterisk+spandsp ; echocancel=yes/no ; rxgain=0/txgain=0 ; increase Wait() ; ...), nothing worked. The only solution that worked for me was to install and use NVFaxDetect. HTH.

Dear All, How can we know the On board supports echo cancellation I have *Digium, Inc. Wildcard TE410P quad-span T1/E1/J1 card 3.3V (rev 02)*board all working fine but sometimes i got echo when user are calling a PRI. is there any way to know on board echo cancellation . regards Dhaval -------------- next part -------------- An HTML attachment was scrubbed...

List, I just tried to swap out our 410 for a 411 and we started have problems with on of our T1's. Setup: Span 1 - Dedicated PRI for long distance. Span 2 - 12 channels fxs_gs outgoing local. 12 Channels em_w incoming DID's. I didn't have any problems with the PRI. The trouble was with the T1. We were unable to place any local calls, and all incoming DID's where garbled.

Hello, There are 3 PRI's connected to the card each from different operators. Especially echo occured on span 3 is really annoying. Configuration files are as follows. Is there something wrong in conf ? Zapata.conf -------------------------- [channels] context=default switchtype=euroisdn usecallerid=yes hidecallerid=no callwaiting=yes usecallingpres=yes callwaitingcallerid=yes

Im curious. Does anyone have experienced echo-problems that later where solved by buying a hardware-echo canceller such as the Wildcard TE411P?

Hi ! I have a Digium TE411P with echo cancelation board. I'm not sure if i need to enable the "echocancelation=yes" in the zapata.conf file. Or since the card hast the echo cancel board, asterisk does not need that option. Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL:

I have echocancel=yes in zapata.conf but when I do a zap show channel 1, I notice echo cancellation is turned off. I followed the article that talks about the order in which the statements need to be in zapata.conf to get echo canceling to work: http://lists.digium.com/pipermail/asterisk-users/2005-June/110615.html But it is still not working. Does anyone know how to get echo

Hello, Avaya has a nice feature that allows you to a) ring both a cellphone and a desktop phone at the same time b) transfer calls (and access other PBX features) from the cellphone that recieved the call, as long as the call is bridged through the PBX c) while talking on the cellphone, pick up the handset on your desktop phone and the call is automatically moved there, hanging up the cellphone

Hi, I'm currently testing SoftEcho, an echo cancellation software for Asterisk from Octasic. I noticed an important increase of the quality of my coms, but I still have a few echo problems. There is an ERL parameter which corresponds to an initial ERL value probably to optimize the echo training or something in that kind. Is there a way to monitor, using one of the zttools, the instant
