HI All, In the pastebin: <http://pastebin.com/KyGXMTP0> http://pastebin.com/KyGXMTP0 is a sip trace. The phone is on the lan and uses proxy: fs_test.bizfocused.com which is 10.10.40.189. In the SIP messages you can see the domain name "fs_test.bizfocused.com". I have a directory that includes <domain name="fs_test.bizfocused.com"> and a user for this subscription. But the SIP response is "SIP/2.0 401 Unauthorized" and the message displayed in FS_CLI is: [WARNING] sofia_reg.c:2376 Can't find user [202@10.10.40.189] You must define a domain called '10.10.40.189' in your directory and add a user with the id="202" attribute and you must configure your device to use the proper domain in its authentication credentials. Why isn't it using the credentials in the domain "fs_test.bizfocused.com"? Thanks, Sean
