Fue desarrollado incialmente en el grupo  de trabajo IETF MMUSIC  (Multiparty Multimedia Session Control) y, a partir de Septiembre de 1999, pas\u00f3 al  grupo de trabajo IETF SIP.   <\/p>\n<p><strong> Historia del Protocolo Sip <\/strong><\/p>\n<p>El 22 de febrero de 1996 Mark Handley y Eve Schooler presentaron al IETF un  borrador del Session Invitation Protocol conocido a hora como SIPv1. El mismo  estaba basado en trabajos anteriores de Thierry Tur letti (INRIA Video conferencing  System o IVS) y de Eve Schooler (Multimedia Conference Control o MMCC). Su  principal fortaleza, heredada por la versi\u00f3n actual de SIP, era el concepto de  registraci\u00f3n, por el cual un usuario informaba a la red d\u00f3nde (en qu\u00e9 host de  Internet) pod\u00eda recibir invitaciones a conferencias . <\/p>\n<p>Esta caracter\u00edstica permit\u00eda la  nomadicidad del usuario.  Ese mismo d\u00eda el Dr. Henning Schulzrinne present\u00f3 u n borrador del Simple  Conference Invitation Protocol (SCIP), que estaba b asado en el HTTP (Hypertext  Transport Protocol). Usaba TCP (Transmission Control Protocol) como protocolo de  transporte. Como identificadores de los usuarios utilizaba direcciones de correo  electr\u00f3nico para permitir el uso de una misma direcci\u00f3n para recibir correos  electr\u00f3nicos e invitaciones a conferencias multimedia. No utilizaba al SDP para la  descripci\u00f3n de los contenidos sino que creaba un mecanismo propio.  <\/p>\n<p>El IETF decidi\u00f3 combinar ambos en un \u00fanico protocolo denominado Session  Initiation Protocol, (es decir cambiando el significado de la inicial I en el acr\u00f3nimo  \u00abSIP\u00bb) y su n\u00famero de versi\u00f3n fue el dos, dando ori gen al SIPv2. En diciembre de  1996 los tres autores (Schulzrinne, Handley y Schooler), presentaron el borrador  del SIPv2. El mismo luego de ser discutido en el gr upo de trabajo MMUSIC   <\/p>\n<p> (Multiparty Multimedia Session Control) del IETF alcanz\u00f3 el grado de \u00abproposed  standard\u00bb en la [RFC 2543] publicada en Febrero de  1999. En septiembre de 1999  se cre\u00f3 el grupo de trabajo SIP en el IETF que continu\u00f3 con el desarrollo del  protocolo y en Junio de 2002 se public\u00f3 la [RFC 326 1] que reemplaz\u00f3 a la anterior  introduciendo modificaciones propuestas durante el  trabajo del grupo SIP. Los  autores de esta \u00faltima RFC, hoy vigente son: Jonnat han Rosenberg, Henning  Schulzrinne, Gonzalo Camarillo, Allan Johnston, Jon Peterson, Robert Sparks, Mark  Handley y Eve Schooler.   <\/p>\n<p>Tomado de:<br \/>\nArroba, M, &#038; Salazar, M.
