Example 3 with ContactList

the class SIPDialog method doTargetRefresh.

     * RFC 3261: Requests within a dialog MAY contain Record-Route and Contact header fields.
     * However, these requests do not cause the dialog's route set to be modified, although they
     * may modify the remote target URI. Specifically, requests that are not target refresh
     * requests do not modify the dialog's remote target URI, and requests that are target refresh
     * requests do. For dialogs that have been established with an
     * 
     * INVITE, the only target refresh request defined is re-INVITE (see Section 14). Other
     * extensions may define different target refresh requests for dialogs established in other
     * ways.
