Hi, a UAC can send in-dialog request to the UAS during an early-dialog:
UAC UAS
-----------------------------------
INVITE --->
<-- 180 (INVITE)
INFO --->
<-- 200 (INFO)
<-- 480 (INVITE)
ACK ---->
But, can a UAS send an in-dialog request to the UAC during an early dialog?
UAC UAS
-----------------------------------
INVITE --->
<-- 180 (INVITE)
<-- INFO
200 (INFO) -->
<-- 480 (INVITE)
ACK ---->
Does it make sense? is illegal?
