[asterisk-r2] problemas con R2 con central NEC

Thu Sep 5 12:04:52 CDT 2013

Marcelo:

El problema que estás experimentando no parece tener relación con
temporizaciones, sino mas bien con errores de reconocimiento de señales MFC
en las interfaces E1 o T1, ya sea problema en la placa del Asterisk o en la
central NEC. No hay forma por ejemplo de confundir un dígito 2 con un
dígito 8, ya que además utilizan combinaciones de frecuencias dispares.
Sugiero pruebes otro hardware, pero no descartes problemas en el medio de
transmisión entre la NEC y el Asterisk (es un E1/T1 directo?, usas algún
tipo de modem?, no hay indicios de microcortes en el medio de trasmisión
que interrumpan por milisegundos alguna de las señales?). Está claro en uno
de los trazados que envías que la NEC te manda un I-2, Asterisk pide
siguiente dígito (A-1) y sin embargo NEC vuelve a enviar I-2 (o simplemente
continua enviando el I-2, pero una breve interrupción hizo creer a Asterisk
que el I-2 fue apagado y vuelto a enviar). No te recomiendo cambiar las
temporizaciones estádares por defecto.

Slds y espero te sea de ayuda.
