This section lists the features added from the previous release, eCall InBand Modem Library 1.1.1.
Minimum Set of Data binary consolidation: A new API and an AT Command enable end user to benefit from a coder to create the binary format of MSD needed to be sent during eCall process to PSAP.
Note: eCall InBand Modem Library implements the 3GPP InBand Modem feature.
3GPP eCall signaling options for emergency call are available with recent firmware starting from R7.44, including R7.47
A PSAP basic test server has been developed by Sierra Wireless for simple PSAP operation / testing. The PSAP Test server application is available in the package.

This section lists the interfaces that have been modified since eCall InBand Modem Library 1.1.1. For more information about the updated interface, please refer to the documentation provided in the eCall InBand Modem Library package.
| API | Comment |
|---|---|
| EncodeMSDMessage | This API encodes the MSD data structure to binary MSD coded with ASN1 protocol |
| eCallMessage_t | The eCallMessage_t structure corresponds to the MSD structure provided by CEN [3] with the following implementation. |
| AT+ASN1MSD | This AT Command is used to update MSD parameters fields and generate a binary MSD coded with ASN1 protocol |
| Id | Description (What/When) | Impacted Domain | Impacted Subdomain | Fixed in |
|---|---|---|---|---|
| 61237 | INBMPUSH is discarded when previous e-call is released by reception cleardown | SAMPLE | OTHER | 1.1.1 |
| 58410 | In HR and FR audio coding scheme MSD transfer success rate is very low | LIBRARY | OTHER | 1.1.0 |
The IVS_Sample application binary size is 112kB for RVDS compiler use.
