I am attempting to deploy Netvanta 3140A router that functions as an SBC between a SIP carrier and the customer's IP PBX. The SBC is currently up and running without issue, but the customer wants to encrypt the signaling and RTP using TLS. From the product feature matrix it looks like this should be supported after version 13.2.1.
The box I am configuring is currently on version 13.4.0, but there doesn't appear to be support for the crypto, TLS profile, or SRTP profile commands required to configure the encryption. Is there a licensing requirement for encryption? Anyone have suggestions as to what I may be missing.
