4.9 Step 9: Configuring SRTP
This step shows how to configure media security. If you configure the Microsoft Mediation
Server to use Secure Real-Time Transport Protocol (SRTP), configure the E-SBC to do so
as well.
Note that SRTP was enabled for Lync Server 2013 when you added an IP Profile for Lync
Server 2013 (see Section 4.6 on page 49).
To configure media security:
1. Open the Media Security page (Configuration tab > VoIP > Media > Media
Security).
Figure 4-28: Media Security Page
2. Configure the parameters like this:
Parameter Example Setting
Media Security
Enable
Master Key Identifier (MKI) Size "1"
Symmetric MKI Negotiation
Enable
3. Click Submit.
4. Reset the E-SBC with a burn to flash for your settings to take effect (see Section 4.16
on page 73).
