Hola tengo problemas para traspasar llamadas desde un terminal asterisk de numeracion 5XXX a un
terminal  en kamailio 3XXX
La configuracion es muy simple
Telefono3XXX<------->Kamailio<------->Asterisk<------->telefono5XXX

cuando llamo de 3100 a 5555
Kamailio le  responde a asterisk con un 484 address incomplete

y cuando lo hago de 5555 a 3000 
Asterisk manda un 403 forbidem

Cual es el problema? Es una configuración bien simple 
de antemano muchas gracias

Adjunto mi configuracion en Asterisk
