Root and Intermediate
Certificates
(in Web UI)
Description	Allows you to specify the SIP Root and Intermediate Certificate files to use
	when the phone uses the TLS transport protocol to setup a call.
	The Root and Intermediate Certificate files contain one root certificate and
	zero or more intermediate certificates which must be placed in order of
	certificate signing with root certificate being the first in the file. If the local
	certificate is signed by some well known certificate authority, then that
	authority provides the user with the Root and Intermediate Certificate files
	(most likely just CA root certificate).
	This parameter is required when configuring TLS (optional for Persistent
	TLS.)
	Note: The certificate files must use the format “.pem”. To create custom
	certificate files to use on your IP phone, contact Aastra Technical Support.
Format	<file name>.pem
Default Value	N/A
Range	N/A
Example	sips root and intermediate certificates: cacert_openser.pem
