1 Introduction
This document describes how to configure the Call Return service in the MTAS.
1.1 Prerequisites
It is assumed that the user of this document is familiar with the Operation & Maintenance (O&M) area, in general.
1.1.1 Licenses
To enable the Call Return service, the MMTel AS Voice Base license must be installed.
For more information about the MMTel AS Voice Base license, refer to MTAS Licenses.
1.1.2 Documents
Before starting any procedure in this document, ensure that the following documents are available:
1.1.3 Conditions
The following condition must apply:
- An Ericsson Command-Line Interface (ECLI) session in Exec mode is in progress.
2 Overview
The Call Return service saves information (such as tel URI and SIP URI) about the last incoming call and provides the end user with the possibility to obtain this information using a Supplementary Service Code (SSC). The user can also call back to the user of the incoming call.
The user can erase their stored last call data by dialing an SSC for a Call Return Erasure procedure.
The Call Return service mainly consists of two parts, saving of the last incoming call and invocation of Call Return.
2.1 Subfunctions
The subfunctions included in the Call Return service are described in this section.
2.1.1 Saving Last Incoming Call
The Call Return service can be configured to be triggered by either all calls or by unanswered calls only. The last incoming call is saved by the terminating MTAS. Depending on configuration, storage of the last incoming call is done locally in MTAS or externally in HSS. The detection of a last incoming call occurs when a "180 Ringing" is received (if Call Return is configured to all calls) or if no "200 OK" is received at the terminating MTAS from the called user (if Call Return is configured to unanswered calls).
In case of local storage in MTAS, the last saved incoming call is kept by the MTAS until either a new incoming call is received or the user is deregistered. During this time, the user can use the Call Return service to make a callback to the caller at any time.
If the last incoming call is stored in HSS, the last incoming call is kept until a new incoming call is received. The saved last incoming call is not lost at user deregistration.
2.1.2 Start Call Return
The served user can make a callback to the caller of the last incoming call by using the SSC in the initial INVITE message, as follows:
- The served user receives an incoming call. The call data is stored.
- The served user dials the SSC for Call Return. There is one SSC for Call Return without announcement prompt and one SSC for Call Return with announcement prompt.
- If the SSC for Call Return without announcement prompt is dialed, a call attempt is made to the caller of the last saved incoming call.
Depending on configuration, three different types of announcement can be played:
- Time and date is included in the announcement independent of interrogation time.
- Time is included, but not date, if invocation day is the same as when the call was saved; date is included, but not time, if invocation day is not the same as when the call was saved.
- "Today" is included in the announcement if invocation day is the same as when the call was saved; "yesterday" is included if invocation day is the day after the call was saved, and day and month is included if invocation day is at least 2 days after the call was saved.
- "Today" is included in the announcement if invocation day is the same as when the call was saved; "yesterday" is included if invocation day is the day after the call was saved, and date is included if invocation day is at least 2 days after the call was saved.
If there is no last incoming call, the served user is informed with an announcement and the Call Return fails.
If the served user does not return a correct invocation code, or if no code is returned, a failure announcement can be sent before the invocation is rejected, depending on the configured value of mtasCrPlayCollectFailureAnnName.
2.1.3 Start Call Return Erasure
The served user can erase the last saved incoming call information by using the SSC in the initial INVITE message, as follows:
- The served user receives an incoming call. The call data is stored.
- The served user dials the SSC for Call Return Erasure.
- The last call saved by call return service is erased and success announcement is played indicating that the last call record is erased. If there is no last incoming call data or CR Erasure fails to erase last call data, the served user is informed with respective announcement.
2.1.4 Play Announcement
To play announcements to the served user, the announcement function in the Media Resource Function Processor (MRFP) is used. The Call Return (CR) service announces the phone number of the last call received by the served user. An option allowing the CR service to send the phone number in the variable part of the announcement in National Number format is available.
2.1.5 Play Collect
The Play Collect function uses an MRFP to play the segment variable announcement to the served user and collect Dual-Tone Multifrequency (DTMF) digit from the served user.
The Call Return service is rejected when it is not possible to play the segmented variable announcements, collect digits, or when faulty digits are collected.
2.1.6 Charging for Call Return
Multimedia Telephony (MMTel) sessions that use the Call Return service support charging. The Credit Control Request (CCR), Initial Request, and Accounting-Request (ACR) Start generated by the originating MTAS on which Call Return was started, or CCR and ACR EVENT messages are generated by the originating MTAS on which Call Return Erasure was started, include the following Attribute-Value Pairs (AVPs) within the MMT Information AVP:
- Supplementary-Service-Information (group)
- Supplementary-Service-Identity
Set to "Call Return without announcement prompt" or "Call Return with announcement prompt".
- Supplementary-Service-Action
Set to "Use of Service".
For more information about offline and online charging, refer to Diameter Offline Charging in MTAS and Diameter Online Charging in MTAS.
2.2 Interaction with Other Services
This section describes the Call Return interactions with other services.
2.2.1 Anonymous Callers
When the served user receives a call from an anonymous caller, the call is saved as the last call. When the served user starts Call Return, an announcement is played informing the served user that the last incoming call was private or anonymous.
2.2.2 SSC
When the auto callback function is started, the called user dials the SSCs for Call Return, one SSC for Call Return without announcement prompt, and one SSC for Call Return with announcement prompt.
3 Call Return Service Configuration
The Call Return service is controlled by the MtasCr MO. An overview of the Call Return MO structure is shown in Figure 1.
For configurable MOs and attributes related to the Call Return service, refer to Managed Object Model (MOM).
3.1 Call Return Administrative State Configuration
The Call Return service is enabled by setting the mtasCrAdministrativeState attribute in the MtasCr MO to 1 (Unlocked). If the mtasCrAdministrativeState is set to 0 (Locked), no Call Return service is provided by the MTAS.
3.2 Configuration Activities
The configuration activities are listed in Table 1.

3.3 Announcement Configuration
When the Call Return service is started with the service code for call return without announcement prompt mtasSscCrComSyntInv, the default setting is that no announcement is played and controlled by the mtasCrAutoAnnName attribute. This attribute is empty by default. If an announcement is to be played, an announcement name, that is, the announcement named by the operator, must be set.
When the Call Return service is started with the service code for call return with announcement prompt mtasSscCrAnnComSyntInv, the default setting is that the announcement is played and controlled by the mtasCrPromptAnnName and mtasCrNoPhonePromptAnnName attributes. These attributes are by default empty. If an announcement is to be played, an announcement name, that is, the announcement named by the operator, must be set.
When the Call Return service is started with the service code for call return Erasure mtasSscCrEraComSyntInv, the default setting is that the announcement is played and controlled by the mtasCrEraSuccessAnnName and mtasCrEraFailureAnnName attributes. These attributes are by default empty. If an announcement is to be played, an announcement name, that is, the announcement named by the operator, must be set.
An option allowing the Call Return service to send the phone number in the variable part of the announcement in National Number format is available.
Call Return announces the phone number of the last call in denormalized format when the following attributes are set to 1 (True):
- The vtasCrCallingPartyDenorm attribute in the VtasCr MO.
- The mtasCrCallingPartyDenorm attribute in the MtasCr MO.
If the attributes are set to 0 (False), Call Return announces the phone number of the last call without modifying it.
For information on announcement handling and Call Return announcement attributes, refer to MTAS Announcement Management Guide.
An example of announcement configuration for Call Return is shown in Example 1:
Example 1 Configuring mtasCrPromptAnnName to Play "Your last call was from xxx at yyyymmdd/hhmm to callback press zz"
This is the structure of a segmented announcement. 1300 = "Your last call was from" (fix part) LastCall =="xxx" variable part (phone number) 2000 = "at" (fix part) LastCallDate = "yyyymmdd" optional variable part(date) LastCallTime = "hhmm" optional variable part(tod) 1500 = "to callback press" (fix part) InvokeCode = "zz" variable part (mtasCrCallReturnCode = zz) |
