| Servicio suplementario de transferencia de llamada para los sistemas UIT-T H.323 |
La Recomendación UIT-T H.450.2 describe los procedimientos y el protocolo de señalización para el servicio suplementario de transferencia de llamadas (SS-CT) en redes conformes a la Recomendación UIT-T H.323 (sistemas de comunicaciones multimedios por paquetes). SS-CT es un servicio suplementario que permite al usuario A servido transformar una llamada existente (usuario A-usuario B) en una nueva llamada entre el usuario B y un usuario C seleccionado por el usuario A. El usuario A puede o no tener establecida una llamada con el usuario C antes de la transferencia de llamada. Esta Recomendación utiliza el "protocolo funcional genérico para el soporte de servicios suplementarios en la Recomendación H.323" definido en la Recomendación UIT-T H.450.1. Los procedimientos y el protocolo de señalización de esta Recomendación provienen del servicio suplementario de transferencia de llamadas especificado en las normas ISO/CEI 13865 y 13869. En esta revisión se corrigen errores hallados en la publicación inicial. |
