4.8 Step 8: Configuring Secure Real-Time Transport

Protocol (SRTP)

If you configure TLS for the SIP transport link between the E-SBC and the Mediation

Server, specify Secure RTP (SRTP) encryption with:

 Required (SRTP should be attempted but do not use encryption if negotiation for

SRTP is unsuccessful)

-OR-

 Optional (attempt to negotiate the use of SRTP to secure media packets. Use RTP if

SRTP cannot be negotiated)

-OR-

 Not used (send media packets using RTP)

If you opt to configure the Mediation Server to use SRTP (Required or Optional),

configure the device to operate in the same manner.

¾ To configure the media security:

1. Open the Media Security page (Configuration tab > Media menu > Media Security).

Figure 4-26: Media Security Page

2. Set the ‘Media Security’ to Enable.

3. Set the ‘Media Security Behavior’ to:

• Mandatory (if Mediation Server is configured to SRTP Required)

• Preferable - Single media (if Mediation Server is configured to SRTP Optional)

4. Set ‘Enable symmetric MKI negotiation' to Enable.

5. Click Submit.

6. Save (burn) the configuration and reset the device.

Notes: To set ‘Media Security Behavior’ to the IP Profile of the Mediation Server,

see the IP Profile Settings.
