Hi everyone, I have the problem not exactly like this one but here is the whole story...
I have installed everything about 3-4 months ago and it worked fine for some time. After a while I noticed that calls drop from time to time, and after few weeks of troubleshooting I asked Digium support to check my installation. Michael Wood from Digium logged in and checked everything, he played a little with source and found that the card is missing interrupts from time to time. After that, together with Mark Spencer who looked at my site also, he decided that I have to send TE410P back because it is bad one, and that I will receive a new one. They were prompt, I have received the new one in few days time, and installed it. The problem is again the same and I have just reported it again to Digium support today. Calls drop from time to time, people are frustrated and therefore I can not put the card in production. The other problem is that I might have few customers very interested in Asterisk and I don't know what to say to them!?!? I hope someone from Digium is reading this mailing list and I hope that our posts can help them to solve these problems.
