Hola,
Antes de todo gracias por vuestra ayuda.
tengo instalado:
Asteris 1.6.2.10
Elastix 2.0
FrePbx 2.0.8.2
A2Billinb 1.7.1

El problema es que cuando intento realizar una llamada desde una extensión de A2Billing no me sale la llamada por el la LINEA pero si lo hago desde una extensión de Elastix esta LINEA funciona correctamente.

Muchas gracias
chimo

Pego la parte final del LOG para que no sea muy largo:
