Anil,
It is not a good idea to use an IP address in the From or Two headers for quite a few reasons. A few examples; if the device is on a IP Private network and you populate this field into the From header it is not unique outside it's own Private network.
In the SDP the 'c' connection field should have the actual IP address of the endpoint - although this may be re-written by a FW ALG for NAT traversal - the 'o' origin line in the SDP should includes the actual IP address of the originator and will not be changed by FW ALG etc.

Hi All,
I understand from the following statement in RFC, that From header SHOULD not contain IP addresses/ports from whom the request has come. If it is so, I can't assume that the information is not used to assume from where (IP address/port) the request has come. Appreciate your response to clarify the point.
As such, it is very important that the From URI not contain IP addresses or the FQDN
of the host on which the UA is running, since these are not logical
names.
Thank you,
Anil
