Matrix SETU ATA211 System Manual 27
The valid range for the port is 1024-65534. Default: 05060.
10. To add ‘rinstance’ in REGISTER? Message, keep this feature enabled. Default: Enabled.
‘rinstance’ is any random value which can be used by the SETU ATA211 to fetch its own contact binding,
i.e. to know the Registration Expiry Timer assigned by the server.
When you enable ‘rinstance’ in Register, SETU ATA211 will generate any random value of 'rinstance' and
include in the REGISTER message. The system will use the registration expiry timer of that contact
binding.
11. Set the Re-registration Timer. This is the time period after which the SETU ATA211 will send registration
request to maintain registration binding with the Registrar server.
The valid range of this timer is 00001- 65535. Default: 3600 seconds.
12. Define the Registration Retry Timer. When a registration attempt fails, SETU ATA211 will resend
registration request to the Registrar Server after the expiry of the Re-registration Timer. The valid range of
this timer is from 00001- 65535. Default: 10 seconds.
13. Click Submit.
