Ayuda con llamadas desatendidas Freepbx

[chelinux]

Saludos amigos acudo a ustedes haber si alguien me puede ayudar con un problema que paso a detallar


Tengo un servidor asterisk 11.25.1 y FreePBX 13.0.192.16 presenta un problema al realizar una transferencia de llamadas desatendidas desde cualquier Sofphone, uso zoiper y también telefonos ips, cuando en zoiper trato de transferir la llamada con ## ext, ni bien presiono ## la llamada finaliza, he verificado en los features codecs y esta habilitada la funcionalidad ## , tambíen he verificado en las configuraciones de sip que estén estos parámetros Asterisk Dial Options y Asterisk Outbound Trunk Dial Options en Tt o Ttr.

Lo raro es que de la noche a la mñana dejo de funcionar

El log me muestra esto
