Hi Joegen Thanks for the response. In my Query2, OpenSBC was not removing the P-Asserted-Identity. In the =20 configuration in OpenSBC, I had added the originating domain as =20 trusted domain for OpenSBC. I assume that all other domains will be =20 non-trusted (OtherDomain). Can you please check this? If OpenSBC is =20 working fine, then I may be incorrectly configuring the OpenSBC. Any =20 pointers will be helpful.
