CHAPTER28 Configuring Supplementary Services
Mediant 1000 Gateway & E-SBC | User's Manual
2. Verify that the caller ID standard (and substandard) of the device matches the standard of the
PBX (using the parameters CallerIDType, BellcoreCallerIDTypeOneSubStandard, and
ETSICallerIDTypeOneSubStandard).
3. Define the number of rings before the device starts the detection of caller ID (using the
parameter RingsBeforeCallerID).
4. Verify that the correct FXO coefficient type is configured (see the CountryCoefficients
parameter in Configuring FXS/FXO Coefficient Types), as the device is unable to recognize
caller ID signals that are distorted.
5. Connect a phone to the analog line of the PBX (instead of to the device's FXO interface) and
verify that it displays the caller ID.
If the above does not solve the problem, you need to record the caller ID signal (and send it to
AudioCodes), as described below.
➢ To record the caller ID signal using the debug recording mechanism:
1. Access the FAE page (by appending "FAE" to the device's IP address in the Web browser's
URL, for example, http://10.13.4.13/FAE).
2. Press the Cmd Shell link.
3. Enter the following commands:
dr
ait <IP address of PC to collect the debug traces sent from the device>
AddChannelIdTrace ALL-WITH-PCM <port number, which starts from 0>
Start
4. Make a call to the FXO.
5. To stop the DR recording, at the CLI prompt, type STOP.
Caller ID on the IP Side
Caller ID for analog interfaces is provided by the SIP From header containing the caller's name and
"number", for example:
From: “John” <SIP:101@10.33.2.2>;tag=35dfsgasd45dg
If Caller ID is restricted (received from Tel or configured in the device), the From header is set to:
From: “anonymous” <anonymous@anonymous.invalid>; tag=35dfsgasd45dg
The P-Asserted (or P-Preferred) headers are used to present the originating party’s caller ID even
when the caller ID is restricted. These headers are used together with the Privacy header.
■ If Caller ID is restricted:
● The From header is set to “anonymous” <anonymous@anonymous.invalid>
● The ‘Privacy: id’ header is included
● The P-Asserted-Identity (or P-Preferred-Identity) header shows the caller ID
■ If Caller ID is allowed:
● The From header shows the caller ID
