7 Putback Transfer

Select the Call Putback checkbox for the SIP line to enable the ability for the

IC system to receive a call from the PSTN or a PBX, perform some processing

on the call and then transfer the call to a non-IC destination (a PBX station or

a remote number), without tying up two IC trunks (one for the original

call

and

one for the call to the destination). By default this setting is unchecked.

Note: Putback does not work with TLS with PRI or FXO.

AudioCodes case # 13540.

8 Security

StrongEncryption must be enabled.

The Mediant requires a feature key with “StrongEncryption” enabled in order to support the required

cipher suites. StrongEncryption may not be enabled by default. To check, follow these steps:

Select Software Update from the left menu. Choose Software Upgrade Key

from the top, view the Key features, and verify:

Security: IPSEC MediaEncryption StrongEncryption EncryptControlProtocol

If “StrongEncryption” is shown, then it is enabled.

When using SRTP the number of available channels decreases by ~25%.

Analog spans have 18 SRTP channels available (out of 24 spans max)

FXO has 3 SRTP channels available (4-port card)

FXS has 3 SRTP channels available (4-port card)

SRTP Settings

Enable Media Security

[EnableMediaSecurity]

Enables or disables the Secure Real-Time Transport Protocol (SRTP).

0 = SRTP is disabled (default).

1 = SRTP is enabled.

Note 1: SRTP is available only if DSPVersionTemplateNumber = 0 or 2.

Note 2:

Use of SRTP has the following limitations. For digital 4-span

modules, the channels are reduced from 120 to 100. For analog modules

with four ports, the 4th port (right-most port on the module) is disabled.

To check the Mediant DSP Version, select Status & Diagnostics on the left,

and Device Information from the top. Under Versions, view DSP Type.

For the rest of the TLS/SRTP configuration refer to either the 5.2 User manual

or the Interactive Intelligence document:
