Hi, I'm trying to get a TE212 working on a Dell PowerEdge 1850 running Debian etch using the latest release of libpri (1.4.0), zaptel (1.4.2.1) and asterisk (1.4.4). The initilization of the Octasic echo canceller seems to fail when the wct4xxp module is loaded. [...] VPM450: echo cancellation for 64 channels Failed to open chip, code 00103017! VPM450: Failed to initialize [...] By looking

...ll, I still haven't seen my first post (cry for help) so I'm not sure if these are going through or not ... I've played with the box all day today ... I got it to quit seg faulting finally by playing with the config files. Currently I have 4 spans configured for a Digium TE420B (With Octastic DSP) Here is my zaptel.conf: (I know the device connected to spans 1-3 are providing clock but I don't know about span 4 so I have no idea if I set these right) span 1,1,0,css,hdb3,crc4 span 2,1,0,css,hdb3,crc4 span 3,1,0,css,hdb3,crc4 span 4,1,0,cas,hdb3 bchan=1-15,17-31 dchan=16 # bchan=3...

We're looking at using 4 or 8 port T1 cards with echo cancellation and are evaluating brands to go with. We know that Sangoma has excellent solutions especially when it comes to echo. But we still have to hear about actual performance of a Digium card using the same Octasic DSP echo canceller. Would appreciate hearing something on this. --------------------------------- Sponsored Link

...Meetings run about 2 hours. Look forward to seeing you there. If you have a product or service you'd like to introduce to our members, send a private message to ejo1(at)soundchoicecomm.com and we'll see if we can't get you listed as next month's sponsor. I'd like to thank Octastic and Cylogistics for their assistance with this months meeting and door prizes. We're looking for a presenter for September and looking forward to a discussion of the LumenVox Speech Recognition for Asterisk software in October on the 13th.

...sion 1.4.15, Extra Sounds 1.4.8, and Freeplay Music On Hold sound files. These sound files are available at http://downloads.digium.com/pub/telephony/sounds/. Future versions of Asterisk will do this automatically from the Makefile (when the sounds are enabled in menuselect). Jean-Marc Valin (from Octastic) had been experimenting with high-pass filters on the existing Asterisk sound files and found a configuration which dramatically reduced the amount of low-frequency sound on the prompts, thereby making them sound much clearer, especially when used with highly compressed codecs such as GSM and G.7...

Ok... I am reluctant to ask this question as I believe that it may be like asking what someones favorite linux distribution is... but I need to make an informed decision. We are getting ready to upgrade from a TE210P to a quad T1 card with echo cancellation. I am trying to decide between the Sangoma card and the Digium card. I need this to have great quality and I need it to work well. I would
