Hi benny
thanks for the reply. Yes I am intended to work with multihomed devices.
ans putting , transport=TCP in URI works.
but I have some problem with INVITE (make call).
the client tries to send the invite to some ip "64.14.244.60" instead
of sending it to the SIP server .
I tried to set my public IP but it does not stop doing this.
What could be the reasons?
