Lo anterior NO se está ejecutando. Fíjate que el Contact del 200 Ok llega con
la IP provada al llamante, por lo que el ACK que envía llega al proxy con el
RURI conteniendo una IP privada del llamado, así que el proxy ruta el ACK a la
IP privada (que obiviamente no llega). Por eso no oyes audio, porque la
negociación del INVITE no acaba (no llega el ACK al llamado, y por eso hay
tantas retransmissiones del 200 OK que no pareces haber observado).
