ECOTEL 3G 16.1. Revised: 1 March 2011.
Group 2 Cause Values
All connections that are rejected with a group 2 cause value (
0xa0-0xaf
) can be mapped to a single cause value
by entering
TranslateG2Cause=<cau>
, whereby
<cau>
represents a cause value in hexadecimal form.
Group 3 Cause Values
All connections that are rejected with a group 3 cause value (
0xb0-0xbf
) can be mapped to a single cause value
by entering
TranslateG3Cause=<cau>
, whereby
<cau>
represents a cause value in hexadecimal form.
Translating Individual Cause Values
The following parameter allows you to translate any of these cause values to any other one:
Translate<cause>=<cause>
. The values entered must be in hexadecimal notation between 00 and 7f.
Translating SIP Causes to ISDN and Vice Versa
You can define a specific translation from SIP responses (4xx - 6xx) to ISDN cause values and vice versa. If nothing
is set, the translation occurs as described in
draft-kotar-sipping-dss1-sip-iw-01.txt
Use the following parameter to translate a cause from ISDN to a specific SIP response:
SipCause<ISDN cause>=<SIP Response>
Repeat the entry to initiate an additional translation.
Use the following parameter to translate a cause from SIP to ISDN:
SipEvent<SIP Response>=<ISDN Cause>
The following range of values applies:
400<= <SIP Cause> <=699 (defined in RFC 3261)
0<= <ISDN Cause> <=127 (DSS1 decimal cause number)

Caller ID (caller identification) is a feature that transmits the calling party number to the called party's telephone
when it rings unless the calling party has restricted number transmission. Caller ID is generated on FXS ports ac-
cording to the V.23 standard. Bear in mind that the called party must have a telephone or device that displays the
calling number in order for this feature to work.
The current firmware version supports the caller ID feature on FXS ports in the following cases:
Calls from VoIP to FXS using the SIP protocol
Calls from VoIP to FXS using the H.323 protocol
Calls from mobile to FXS
