3-383Click OK. The new participant is added to the Participants list. You can  save the participant properties to the Address Book so you can easily invite the participant to future conferences.SIP Address/
Type
(SIP Only)
Select the format in which the SIP address is written:
•SIP URI - Uses the format of an E-mail address, 
typically containing a user name and a host name: 
sip:[user]@[host]. For example, 
sip:dan@polycom.com.
•TEL URI - Used when the endpoint does not 
specify the domain that should interpret a 
telephone number that has been input by the user. 
Rather, each domain through which the request 
passes would be given that opportunity. As an 
example, a user in an airport might log in and send 
requests through an outbound proxy in the airport. 
If the users enters “411” (this is the phone number 
for local directory assistance in the United States), 
this number needs to be interpreted and 
processed by the outbound proxy in the airport, 
and not by the user's home domain. 
In this case, tel: 411 is the correct choice.
Note: This field is removed from the dialog box when 
the ISDN/PSTN protocol is selected.
