Parameter
Web: Copy Destination Number to
Redirect Number
CLI: copy-dst-to-redirect-number
[IpProfile_CopyDest2RedirectNumber]
Web: Media Security Behavior
CLI: media-security-behaviour
[IpProfile_MediaSecurityBehaviour]
Version 6.8
Note: The corresponding global parameter is
ProgressIndicator2IP.
Enables the device to copy the called number, received in
the SIP INVITE message, to the redirect number in the
outgoing Q.931 Setup message, for IP-to-Tel calls. Thus,
even if there is no SIP Diversion or History header in the
incoming INVITE message, the outgoing Q.931 Setup
message will contain a redirect number.

[0] Disable (default).

[1] After Manipulation = Copies the called number after
manipulation. The device first performs IP-to-Tel
destination phone number manipulation, and only then
copies the manipulated called number to the redirect
number sent in the Q.931 Setup message to the Tel.
Thus, the called and redirect numbers are the same.

[2] Before Manipulation = Copies the called number
before manipulation. The device first copies the original
called number to the SIP Diversion header, and then
performs IP-to-Tel destination phone number
manipulation. Thus, the called (i.e., SIP To header) and
redirect (i.e., SIP Diversion header) numbers are
different.
Note: The corresponding global parameter is
CopyDest2RedirectNumber.
Defines the handling of SRTP for this SIP entity.

[-1] Not Configured = Applies the settings of the
corresponding global parameter,
MediaSecurityBehaviour.

[0] Preferable = (Default) The device initiates encrypted
calls to this SIP entity. However, if negotiation of the
cipher suite fails, an unencrypted call is established.
The device accepts incoming calls received from the
SIP entity that don't include encryption information.

[1] Mandatory = The device initiates encrypted calls to
this SIP entity, but if negotiation of the cipher suite fails,
the call is terminated. The device rejects incoming calls
received from the SIP entity that don't include
encryption information.

[2] Disable = This SIP entity does not support
encrypted calls (i.e., SRTP).

[3] Preferable - Single Media = The device sends SDP
with a single media ('m=') line only (e.g., m=audio 6000
RTP/AVP 4 0 70 96) with RTP/AVP and crypto keys.
The SIP entity can respond with SRTP or RTP
parameters:

If the SIP entity does not support SRTP, it uses
RTP and ignores the crypto lines.

If the device receives an SDP offer with a single
media (as shown above) from the SIP entity, it
responds with SRTP (RTP/SAVP) if the
EnableMediaSecurity parameter is set to 1. If
SRTP is not supported (i.e., EnableMediaSecurity
is set to 0), it responds with RTP.
