NA NA sip persistent tls keep alive Allows you to configure the keep-alive feature for persistent TLS connec-
tions only. When this feature is configured, the phone will send keep-alive
pings to the proxy server at configured intervals.
The keep-alive feature for persistent TLS connections performs the fol-
lowing functionalities:
• After a persistent TLS connection is established or re-established, acti-
vate the keep-alive, which will send CRLF to peer periodically.
• The phone will retry the connection automatically when a persistent
TLS connection is down.
• When a persistent TLS connection is re-established (primary is up or
primary is down and backup is up), refresh registration of the accounts
associated with the connection.
• When a persistent TLS connection to primary is down, switch to
backup if connection to backup is working.
NA NA sip send sips over tls 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 ena-
bled.
For more information, see Chapter 6, the section, “Transport Layer Secu-
rity (TLS)” on page6-16.
N/A Root and Intermediate
Certificates Filename
sips root and intermediate
certificates
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 Certifi-
cate 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 certifi-
cate files to use on your IP phone, contact Aastra Technical Support.
For more information, see Chapter 6, the section, “Transport Layer Secu-
rity (TLS)” on page6-16.
N/A Local Certificate
Filename
sips local certificate Allows you to specify the Local Certificate file to use when the phone uses
the TLS transport protocol to setup a call.
This parameter is required when configuring TLS (optional for Persistent
TLS.)
Note:
The certificate file must use the format “.pem”. To create specific certificate
files to use on your IP phone, contact Aastra Technical Support.
For more information, see Chapter 6, the section, “Transport Layer Secu-
rity (TLS)” on page6-16.
