Lo reporte a Telmex y me dijeron que era problema del PBX no de la troncal, yo les comento que de repente telmex esta bloqueando los canales
se va el RX a 1101 y se vuelven a levantar
Este es mi dahdi y mi channels, ven algo raro? No es el primer E1 que programo, ya cambie la tarjeta, el cable, el balun y siguen los problemas
Les paso el dahdi y el channels
