N/A

Trusted Certificates 
Filename

sips trusted certificates Allows you to specify the Trusted Certificate 

files to use when the phone uses the TLS 
transport protocol to setup a call.

The Trusted Certificate files define a list of 
trusted certificates. The phone’s trusted list 
must contain the CA root certificates for all the 
servers it is connecting to. For example, if the 
phone is connecting to server A which has a 
certificate signed by CA1, and server B which 
has a certificate signed by CA2, the phone 
must have CA1 root certificate and CA2 root 
certificate in its Trusted Certificate file.

This parameter is required when configuring 
TLS or 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.
