SIP MLT Features

SIP MLT Encryption
It is possible to encrypt the signalling data and the speech data (RTP) between one or more DT800/DT700
extensions and the GPZ-IPLE card.
A 128 bit AES encryption technique is used.
If NetLink is in operation, the DT800/DT700 must be registered to the Primary system to be able to use the
Encryption feature.
It is possible to set only the signalling to be encrypted or the signalling and the RTP together, it is not
possible to encrypt only the RTP without encrypting the signalling.
If the call is between two DT800/DT700's with Peer to Peer enabled and both extensions are set to use
encryption, the signalling and RTP will be encrypted regardless of the settings in system programming.
Only DT800/DT700 extensions can use the encryption feature, it is not supported for standard SIP
extensions or any networking protocol.
If the speech is encrypted (sRTP) the number of available DSP's on the GPZ-IPLE card may be reduced
(depending on the codec used). See the GPZ-IPLE DSP Information page for more information.
