[SIPForum-discussion] Scenario of SIP

[vijay pal]

Hi All,

These days we are using a function in our  mobiles like Verizon mobile and
that is a IVR"While your call is being connected please listen the music".
So my question is what is this type of media? Is it early media or some
thing else? and if it is early media then how can it be before the session
establishment, I mean to say  before 183(session progress)?
Please help me to understand this Scenario.


Thanks and Regards
Vijay Pal
