5.91. How to change the database username/password
The auto installer will use the “sa” username with “srEgtknj34f” password by default.
Install the SQL Server Management Studio if not already installed.
Login with the old credentials.
Open “Security” -> “Logins”. From here you can easily add/remove any users or change passwords.
Before changing the default user settings, stop the mserver service (By launching the stop.bat file or from Services).
Change the database settings in the mizuserver.ini configuration file.
Restart the voip service.
5.92. Performance optimizations -fine-tune
Disable rtp routing whenever possible
Set getpacketloss global config option to 0 (this will enable fix rtp relaye)
Disable resellerbilling if possible
Set trace level to 1
Set outboundprefix1,
outboundprefix1 and outboundprefix2
Disable early media on client and server side
Increase media frame/packet
Set “allowlastwrongnum” to false
Increase maxasyncrecthreads (set to number of available cpu)
Set threadsafeoops to 1 (or to 2 if there are stability issues)
Enable/disable useasynctransportthread (global config option for async send, defaults to -1 which depends on cpu count)
Use MS-SQL query governor
Turn off disk write-cache buffer caching if you have a separate power supply
Set the usevgetpriceint to true (also requires dbversion 124; with this mode, + and 0 prefixes are not allowed in the billing. Only numbers)
Setup user caching (set “cacheregistrations” to 2)
Set checkfilecontents to false.
Set updateusrcalldate to 0
Adjust DEFQUEUELEN
Set REBUILDREGCLIENTS to -1
Remove performance counters, lasttoops
Set waitforsqlupdate to 0
Set validatesipmessages to 0
Set “useasynctransportthread” to 1 (especially if TCP is used)
Optimize the number of threads (“thead”settings)
