Asterisk UniMRCP Modules 1.7.0 release has been published and can be downloaded from the following location:

asterisk-modules-1.7.0

The released source package contains bare modules compatible with the following versions of Asterisk and UniMRCP:

• Asterisk 1.6, 1.8, 10, 11, 12, 13, 14, 15, 16 and 17
• UniMRCP > 1.1.0

This release adds support for a persistent MRCP session being used by multiple invocations of MRCPRecog(), MRCPSynth() and SynthAndRecog() applications in the scope of the same call. The release also fixes a couple of minor problems.

All the changes are made to be backward compatible. Nothing has to be changed in the existing applications.

The detailed list of changes introduced in this release follows.

1. Generic Speech Recognition API (res_speech_unimrcp.so)

• N/A.

2. Dialplan Applications (app_unimrcp.so)

2.1. MRCPSynth()

• Added a new option 'plt' allowing to have persistent session lifetime, where an MRCP session is created on demand, reused and destroyed on hang-up.
• Added a new option 'dse' allowing to specify a particular datastore entry. A datastore entry is associated to an MRCP session. There can be multiple datastore entries used in the scope of the same call. If the parameter is not set, then the default datastore entry is used.
• Added a new option 'sbs' indicating whether or not to always stop barged synthesis request. Thanks @sfgeorge. (Pull request #36)

2.2. MRCPRecog()

• Added a new option 'plt' allowing to have persistent session lifetime, where an MRCP session is created on demand, reused and destroyed on hang-up.
• Added a new option 'dse' allowing to specify a particular datastore entry. A datastore entry is associated to an MRCP session. There can be multiple datastore entries used in the scope of the same call. If the parameter is not set, then the default datastore entry is used.

2.3. SynthAndRecog()

• Added a new option 'plt' allowing to have persistent session lifetime, where an MRCP session is created on demand, reused and destroyed on hang-up.
• Added a new option 'dse' allowing to specify a particular datastore entry. A datastore entry is associated to an MRCP session. There can be multiple datastore entries used in the scope of the same call. If the parameter is not set, then the default datastore entry is used.
• Set end_of_prompt when audio file complete on Asterisk >= 11. Thanks @sfgeorge.
• Added a new log statement "File is over" for Asterisk >= 11. Thanks @sfgeorge.
• Added a new option 'sbs' indicating whether or not to always stop barged synthesis request. Thanks @sfgeorge. (Pull request #36)
