Mitel 6800i Series SIP Phone Release 4.0.0 SP1 Administrator Guide
Additionally the "sip send sips over tls" parameter allows administrators the ability to manually
configure the IP phones to use either the SIP or SIPS URI scheme when TLS or persistent TLS
is enabled. Disabling the "sip send sips over tls" parameter (i.e. defining the parameter as
"0" in the configuration files) ensures the IP phones use the SIP URI scheme when TLS or
persistent TLS is enabled. Enabling the parameter (i.e. defining the parameter as "1") ensures
the phones use the SIPS URI scheme in such scenarios. The SIPS URI scheme is used by
default.
CONFIGURING TLS USING THE CONFIGURATION FILES
You use the following parameters to configure TLS in the configuration files:
• sip transport protocol
