My TE411p does not seem to like to have two PRIs from different telcos (span 1 and span 2). I can get one working, but not the other. However, if I use vpmsupport=0 when loading the wct4xxp module, they both work. But here is the problem, vpmsupport=0 disables the on board echo cancellation. Any ideas? BTW, here is zaptel.conf span=1,1,0,esf,b8zs span=2,2,0,esf,b8zs bchan=1-23 dchan=24 bchan=25-47 dchan=48 loadzone=us defaultzone=us

Any ideas?You should contact Digium support about this. You paid for it when you bought the card, they are the ones that are most likely to be able to help you with your problem. Matthew Fredrickson
You should really take this up with Digium support, and don't forget to share your experience.

I just tried it. Same problem, one of the two spans is not working. If I load wct4xxp with vpmsupport=0, then both spans working. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Steven Totaro Sent: Thursday, April 27, 2006 1:23 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: RE: [Asterisk-Users] PRIs from two different telco Try setting the timing to zero on both spans?> > span=1,0,0,esf,b8zs > > span=2,0,0,esf,b8zs> -----Original Message----- > From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users- > bounces@lists.digium.com] On Behalf Of C F > Sent: Thursday, April 27, 2006 12:29 PM > To: Asterisk Users Mailing List - Non-Commercial Discussion > Subject: Re: [Asterisk-Users] PRIs from two different telco > > You should really take this up with Digium support, and don't forget > to share your experience. > > On 4/27/06, Wai Wu <wwu@calltrol.com> wrote: > > > > My TE411p does not seem to like to have two PRIs from differenttelcos> > (span 1 and span 2).

[Asterisk-Users] PRIs from two different telco

Yes. It is always the same pri regardless port on the TE411P. If I disable the hardware echo canceling with vpmsupport=0, they will all work. I called Digium tech support the last hour. They ssh into my machine and can't find anything wong with the configuration, and he suggest to remove the daughter card to see if the same thing happens. I have a feeling that he heading in the direction of we having bad card. We should know by the end of today. ________________________________ From: asterisk-users-bounces@lists.digium.com on behalf of Gary Reuter Sent: Thu 4/27/2006 3:03 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] PRIs from two different telco I have 3 PRIs from different providers, and the fourth port is to a legacy Meridian system...

Time to report back. We took out the daughter board (no more hardware echo canceling) on the TE411P, and the problem is gone. Guess we have to RMA the card. ________________________________ From: asterisk-users-bounces@lists.digium.com on behalf of Wai Wu Sent: Thu 4/27/2006 3:30 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: RE: [Asterisk-Users] PRIs from two different telco Yes.

Time to report back on this. We took out the daughter board from the TE411P as per Digium's request, and the problem went away. We might just had a bad card. One question thought, does the hardware echo cancellation work much better than software? ________________________________ From: asterisk-users-bounces@lists.digium.com on behalf of Wai Wu Sent: Thu 4/27/2006 3:30 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: RE: [Asterisk-Users] PRIs from two different telco Yes.

I don't realy mind if the algorithm work the same. The true issue here is how much CPU load is it going to save me over the software echo cancellation. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Don Pobanz Sent: Friday, April 28, 2006 9:46 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] PRIs from two different telco Wai Wu wrote:> One question thought, does > the hardware echo cancellation work much better than software?I bought a Digium TE411P hoping the hardware echo canceler would improve my echo problems over the software echo canceler, but had no performance improvement.
