Hi Jorge, I think the firstcic values in your config are not correct. On our system we gave 5 E1's per linkset and the following config: firstcic => 1 firstcic => 33 firstcic => 65 firstcic => 97 firstcic => 129 Every E1 has 32 channels, start counting with 0. So E1 has channel 0 - 31. The second E1 has channel 32 - 63 But the first channel is used a timing channel, And you have to give the CIC of the first voice channel.
