Hi,
Can anybody explain me the behavior in case UE recieves the INVITE request
with From Header as:
From: http://www.mytest.test;tag=1
The difference in the above uri is that it is neither SIP/SIPS/TEL
URI.Should we respond with 200 Ok for the above request?
Regards
Sumant
Yes; you should allow responding with a 200 response if you want to be
interoperable with devices sending such atypical From URI schemes.
The following link indicates the various registered URI schemes.

Hi Sumant,
According to RFC 3261, ABNF grammer, I guess we can accept the From: header.
scheme = ALPHA *( ALPHA / DIGIT / + / - / . )
From= ( From / f ) HCOLON from-spec
from-spec = ( name-addr / addr-spec )
*( SEMI from-param )
addr-spec =
3261 allows this.
Since the From URI doesn't have a role in routing messages, the
infrastructure should deliver the request to some server responsible for
the R-URI. Once it gets there, the recipient can reject the request if
it wants. For instance you could return a 403 Forbidden response.
