Corte en llamadas y bloqueo de canales en e1

Question

Tengo un problema que llevo varios meses y no he podido darle solucion, y tampoco he sabido demostrarle a la compañia que tenemos un problema grave ya que siempre dice que esta bien de su lado y que el problema es de mi pbx.

tengo una e1 de 10 trondales que llegan a mi site por cobre, lo recibo atraves de un Astribank, resulta que el primer y principal problema que tengo es que se cortan las llamadas derrepente, sin un tiempo determinado y sin ningun aviso o ruido de la caida de la llamada, solo al darnos cuenta no escuchamos la persona del otro lado, al momento del corte, todas las llamadas que esten usando las troncales se ven afectadas las llamadas entr extensiones siguen vivas, ya no se por donde busacarle.

el segundo problema que observamos es que unicamente podemos usar simultaneamente 5 de las 10 troncales, al momento de usar una sexto canal, desconecta una de las 5 que inicialmente estan activas, sera que sea problema de configuracion? o es problema del servicio que estoy recibiendo de la compañia de telefonos?.

ojala me puedan ayudar para buscar una solucion.

De antemano, mil gracias.
