Hi, mea maxima culpa.
I've found the cause, however Sangoma card and driver are working excellent. Just for the archive, to help someone else, maybe having the same problem: In order to test my system before bringing it to the data center, I plugged in a loop cable. Therefore I had to switch the E1 clock mode to "master" instead of "normal". Of course I knew, I have to switch it back to "normal", before connecting to the real carrier, but I forgot. Anyway, the dependence of the 4:50 minutes remains funny. Maybe a function of the divergence of the two clocks (my one the the carrier's one). Thank you answering anyway!
