[Users] keep alive using RE-INVITE

[Javier Ramirez]

Tan simple como poner un timer en cada llamada para que a los 30 segundos mande un INVITE igual al primero.
Hubiera preferido una respuesta de: "no se como hacerlo"
yo solo queria saber si se podia hacer con el openser, es decir, si el openser ya lo tenia !
no era tan dificil la pregunta
saludos
Javier

  Javier,

   

  reInvites would have to be generated by some dialog stateful component of the call.

  Depending on your network setup, this could be either endpoints or some B2BUA in the middle.

  openSER is not dialog stateful (openSER is transaction stateful ) and thusly cannot generate reInvites.

   

  Hope this helps

   

   

  T.R.

    Javier,

    I guess the RFC3261 or google (SIP + reINVITE) are the best source for 
    looking into.
