Hola a Todos.
Estoy configurando un Elastix 2.4, y estoy experimentando un problema con una troncal de Alestra.
Tengo configurada una tarjeta Sangoma A104DE y en el Span 4 es donde estoy conectando la troncal mfcr2 de Alestra, las llamadas de entrada funcionan sin problema, pero en las llamadas de salida salta el mensaje de que todas los circuitos se encuentran ocupados... Levanté un reporte a Alestra y me comentaron que mi equipo en la señalización de R2 les está enviando una categoría de abonado de operadora (1) en vez de enviar una categoría de usuario normal (2) y es por eso que la central responde con un (4) que es una señal de congestión.
Analizando en el Elastix la traza de las llamadas que envío por Alestra efectivamente veo que les envío un 1 en la categoría de y la central me regresa un 4

[18:29:17:317] [Thread: 47590543259968] [Chan 94] - MF Rx << 4 [ON]
Y supongo que esto es por que en el Span 4 de /etc/asterisk/dahdi-channels.conf, tengo mfcr2_category, como national_suscriber. Hice un cambio y lo puse como mfcr2_category=national_priority_suscriber, pero aún así en la traza sigue enviando un 1 a la central y esta responde con un 4.
Aclaro que después del cambio, reinicié dahdi, wanrouter, asterisk, y como medida extrema, reinicié la caja completa y el problema continua.
A continuación les comparto lo que tengo configurado referente al E1.
