[Serusers] Questions about SER+SERWEB+SEMS deployment

Hello List, I'm a new user of SER. Just some questions about how I could deploy SER+SERWEB+SEMS, possibly on separate hosts, as I plan to have more than one SER proxy server with a centralized web server and media/voice mail server (1) Basically what features will I be missing if I decide to omit the fifo functions (if possible) in serweb? ( aliases, add new contact SIP address and who are online would be three features, right?) (2) I saw in one of the threads that there is a fifo_server.php file available for fifo-Internet relay, but not quite sure how to use it. Could someone give me some pointers? (3) Somewhere in the mailing list I saw the "fifo_db_url" global declaration, is it a feature only available in version 0.9.0? And is there a serweb version that will work with ser 0.9.0? (4) I have not tried SEMS yet, but since it also communicates with SER via fifo, I would assume it has to be in the same host as SER, right? Are there any existing modules/plugins that will allow SER and SEMS on different hosts? If not, would it be more scalable if I build an Asterisk box to handle voice mails? (5) If I have multiple SER proxy servers on different hosts, how could UA Alpha registered with SER proxy A be able to call UA beta which registered with SER proxy B? What setup/configuration would I need? I know I have some dumb questions - I'm new to voip and SER. Please try to help me out, I would really appreciate it. Thank you in advance. _________________________________________________________________ Take charge with a pop-up guard built on patented Microsoft® SmartScreen Technology. http://join.msn.com/?pgmarket=en-ca&page=byoa/prem&xAPID=1994&D… Start enjoying all the benefits of MSN® Premium right now and get the first two months FREE*.
