[SIPForum-discussion] Re-INVITE behavior

[Gonzalo Gasca]

Hi forum,

Have the following question:
When we get a RE-INVITE with SDP with same SDP information as previous 200
OK, should we forward that REINVITE or answer with previous ACK
information.?

Call flow:

Endpoint (a)‹> B2BUA (a1) ---> B2BUA(a2) ---> SBC ---> B2BUA(b) --->
Conference bridge (b)

When I call from endpoint a, conference bridge b answers, in this case

In B2BUA(a2)

 INVITE           --->
TRYING          <---
RINGING        <---
200 OK /SDP <---
ACK/SDP       --->
INVITE/SDP <---
TRYING         <---
200 OK         --->
ACK              <---
BYE             --->

Thanks!

Gonzalo
