AuthUserName The User ID to authenticate to a SIP UAS (User Agent 
Server) when an outbound SIP request sent by the handset 
is challenged by the UAS with a 401 or 407 response.
None
AuthPassword The Password (corresponding to AuthUserName) to 
authenticate to a SIP UAS (User Agent Server) when an 
outbound SIP request sent by the handset is challenged by 
the UAS with a 401 or 407 response.
None
URI This parameter affects the way the AOR is formed by the 
handset in outbound SIP Requests. The AOR has the 
format: user@domain. 
If the value of URI is empty, the handset gets the user 
portion of its AOR from the AuthUserName, and the 
domain portion the value of ITSP Profile’s 
UserAgentDomain if it isn’t empty, or that of the 
ProxyServer otherwise. 
If the value of URI isn’t empty and doesn’t contain “@”, it is 
used as the user portion of the AOR while the domain 
portion is formed the usual way.
If the value of URI contains @, it is interpreted as a full AOR 
and handset takes it as the AOR as is.
Some examples:
• Let ProxyServer = sip.myitsp.com, AuthUserName 
= 4089991123, URI=[empty], 
UserAgentDomain=[empty], then
 AOR = 4089991123@sip.myitsp.com
• Change UserAgentDomain to users.myitsp.com, 
then
 AOR = 4089991123@users.myitsp.com
• Change URI to bobdylan, then
 AOR = bobdylan@users.myitsp.com
• Change URI to 
bobdylan@superusers.myitsp.com, then
 AOR = bobdylan@superusers.myitsp.com
Note: In all cases, the handset uses AuthUserName and 
AuthUserPassword to compute authorization if challenged 
by a 401 or 407 response.
None
