Hi all, I need your lights :) There are many hardware provider for E1 cards on the market, what's your exeperience with E1 and what's the preferred provider for Asterisk out of Digium? Olivier

Wolfgang: What kind of CPU-load issue on A104? Could you give me a link or something? I also use A104 and it works very good, but recently I noticed a behavior which is maybe connected with this issue, so more info would be very helpful for me :) Thanks!

I don't know why it happened but it did it again and again. Now I have a Sangoma A104 and it looks O.K. There is an issue with CPU-load but as far as I can see it's no problem. We will connect this machine to the telco line the next days. cu, Wolfgang _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Thanks a lot Wolfgang! I use Dell PE2850, so probably this issue does not directly affect my system. But I will read thread anyway. What is happening is that under higher load (60 calls, for example) the Asterisk sometimes stops responding in a time manner (AMI messages are delayed, etc). Sometimes also D-Channel goes down and up again. But I'm not sure if this is Sangoma related problem or Asterisk locking issue. Regards!

First Msg-id is: <87bqtubfc4.fsf@beck.kurtkrenn.com>, Subject is: "Experience with IBM X346 machines and Sangoma" This machine is not connected to any line at the moment. So I can not say if this issue makes a real problem. I can give more info next week. What did you observe on your machine? cu, Wolfgang _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Does one of them perform noticable better than the other. - Sebastian

I was just wondering about the "almost". Armin

The analog A200 has (optional) hardware EC too.>> So on the Sangoma echo cancel does not affect CPU performance while on >> the Junghanns it does. > > And in terms of quality?

If you have unlimited CPU power (or the hardware EC is very bad implemented) it could be of the same quality. In fact the Sangoma has 128ms echo cancel per channel. As far as I know neither the Digum harware echo cancel nor the available software solutions offers this. Christian

As far as I know > neither the Digum harware echo cancel nor the available software > solutions offers this.I thought the Eicon cards were the only ones with 128ms echo-cancel ;-) Anyway, what time frame do the software implementations use? Even with enough CPU power, do these software solutions provide as good results as a DSP on board? Armin
