Mon Nov 1 11:23:14 CDT 2010

Descripci&oacute;n del Problema.
Tengo un E1 conectado a mi Xorcom, pbx con asterisk 1.4.29, la conexi&oacute;n es muy intermitente, un rato di funciona y otro momento no me funciona, prob&eacute; con otro e1 tambi&eacute;n de maxcom y me funciona perfectamente, pero cuando hacen test de maxcom el E1 que no me funciona pues sale positivo en las pruebas,
Y lo m&aacute;s raro es lo siguiente:
