Nope. > 3) Must I call nua_create() once per line? You don't have to call nua_create() for each line, but you can do. If you end up doing so, you can force all the nua agents to run in the same thread by calling su_root_threading(root, 0) before nua_create() calls. > I have an embedded environment, so I want to minimize memory/CPU > utilization. What is the best way to do this using Sofia SIP stack? So how to run multiple lines in single agent? You can use the SIP url userpart to identify the line. Because the From and To headers don't always identify correct line, you have to use userpart in the Contact and request-URI. You can either add the Contact header explicitly to the nua_register(), nua_invite() and nua_respond() calls (and other dialog-initiating reques/responses like REFER, SUBSCRIBE and NOTIFY if you use them) or let the stack generate the Contact header but specify the userpart with NUTAG_M_USERPARTt(). -- Pekka.Pessi mail at nokia.com ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
