84 SIP Deskphones Release 6.4 Installation and Maintenance Guide
Network ping diagnostics
A Ping softkey appears when you view a network address in the Avaya Menu Network
Information... option. Users can validate the routing to provisioned addresses using the Ping
softkey.
Administrators can validate arbitrary addresses with the “Host to Ping” function using the Craft
local procedure on
Installing static addressing on page 47.
Ping results display in a succession of pop-up windows.
SRTP provisioning
SRTP is now supported (with TLS). To use SRTP, the network region codec set must have
media encryption set up for each region that calls may traverse.
When SRTP is provisioned in Communication Manager, the default cryptosuite used is
‘aescm128-hmac80’. The 9601, 9608, 9608G, 9611G, 9621G, or 9641G IP deskphone also
assumes that no encryption is an option provisioned in Communication Manager. If
Communication Manager is provisioned with the cryptosuite aescm128-hmac80, then the
following entry must be in the 46xxsettings.txt file:
SET MEDIAENCRYPTION "1,9"
If some other encryption set is required, the string must be set appropriately in the
46xxsettings.txt file.
