[asterisk-r2] Fwd: Problema con Astribank y E1 R2

Thu Jul 24 12:43:54 CDT 2014

Es debido a un problema con el módulo DAHDI de Asterisk, a partir de la versión 2.7 tiene problemas con señalización R2. Lo que debes hacer es bajar de versión el DAHDI a la 2.6.

Tengo problemas para conectarme a la central Ericsson del
proveedor de servicios usando un Astribank de XORCOM con dos E1 R2 configurados
con todos los canales bidireccionales.

La PBX y la central pública se conectan y las llamadas entran
y salen pero solo por el canal uno de cada uno de los E1. Si la comunicación en
cualquier dirección se intenta por otro canal que no sea los mencionados la
central y la PBX intercambian señalización pero antes de intercambiar del número
marcado la central publica corta la comunicación.

A continuación los logs de una llamada fallida por el canal 3 de un flujo. Incluyo también algunos ficheros de
configuración.
