Hi,
Consider this scenario :
A & B are two user agents.
A B
INV
-------------------------------->
200
<--------------------------------
ACK
-------------------------------->
================= Dialog established.
INV(hold) BYE
-----------> <--------
==============================================
In this scenario, A sends an Invite(hold), just when B has sent a BYE. How
should user agent B respond to the INVITE ? It has already sent a BYE when it receives
an Invite. Is it supposed to send a 4XX - maybe a 487 Request Terminated ??
Regards,
Reshmi
