[SIPForum-discussion] REG: reinvite

[Routhu Rajeswari]

Hi all ,

I am trying to establish a call with a useragent1 with bhsdp to put him on
hold . Now if any other useragent2 calls useragent1 iam sending reinvite to
useragent1 with sdp2 .

But when i try this scenario iam getting the reinvite on second line while
the original call was established on first line. Iam not understanding the
difference between the original invite and reinvite.Or is it because of
container may not be supporting reinvites.

Here are the invites



*Original invite --- black hole sdp*
