Can I limit the users of Upper Registration or Thru Registration?
You can limit users through the Dial Plan.- [Brekeke SIP Server Admintool]>[Configuration]>[SIP], set [Upper Registration]/[Thru Registration] to OFF.
- To allow only specific users to use these features, make a Dial Plan rule and include either of the following in the Deploy Patterns field
- net.registrar.upper.allow = true
- net.registrar.thru.allow = true
- net.registrar.upper.allow = true
