Hello, I am trying to write a simple application to test VoIP capabilities over a GPRS link. To do such a thing I've used Speex 1.1.11 to capture voice and compress it as much as posible. And now, I am taking care about the communication process. Because it is supposed to be a voice application, I need at least the use of RTP to ensure proper handling of packets over the GPRS network. So far, I've been working on RTP client examples, and I've read the Speex draft too. But still, I don't know how Payload Type must be specified. In the Speex draft it says 'dynamically allocated payload type SHOULD be chosen', but I don't understand what this means. Thanks a lot for any tip. ______________________ Este mensaje, y en su caso, cualquier fichero anexo al mismo, puede contener informacion clasificada por su emisor como confidencial en el marco de su Sistema de Gestion de Seguridad de la Informacion siendo para uso exclusivo del destinatario, quedando prohibida su divulgacion copia o distribucion a terceros sin la autorizacion expresa del remitente.
