[Kamailio-Users-ES] Fallo al transferir llamadas externas

Hola.
Tengo una instalación con FXO Grandstream y Openser con varios teléfonos
IP registrados, y el problema que tengo es que las llamadas que entran a
través del FXO, al transferirlas entre teléfonos IP se cortan. No se
pueden transferir llamadas externas entre teléfonos IP. Sin embargo con
las llamadas internas entre los propios teléfonos IP no hay ningún
problema para transferirlas. Este problema ha surgido a raíz de cambiar
el modo de funcionamiento del FXO para que las llamadas entrantes suenen
directamente en los teléfonos IP. Con la configuración anterior según la
cual cuando entraba la llamada en el FXO era necesario una segunda
marcación para seleccionar la extensión IP, la transferencia de llamadas
funcionaba correctamente.
¿Me puede por favor echar alguien una mano a identificar la causa del
corte en las transferencias? Muchas gracias de antemano.
Adjunto traza ngrep, de una llamada externa entrante a la extensión 43 a
través del canal FXO 9873, y el intento de transferencia de esta llamada
desde la extensión 43 hacia la extensión 42. La traza a partir de
haberse atendido ya la llamada externa en la extensión 42.
