Unable to hear any audio while playing wav/tts file

I am running an application to play a wav/tts file to a phone. However, I am unable to hear any audio. The logs reveal the following messages: <field name="terminationCondition">deviceerror</field>


  • One of the reasons for this error could be HMP failure. Verify that the HMP is running.
    • Go to Start > Programs > Intel Net Structure HMP > Configuration Manager DCM
    • HMP_Software#0 should depict a green arrow. If it isn't, restart HMP.
    • This error could also occur if the media engine has been installed on VMWare. We do not recommend this. Reinstall on proper machine to resolve issue.

SDK License not visible

I have applied an SDK license to my media engine, and the available licenses depicted on the cuae admin interface reflect this. However, application logs show the following: Info: MCP Resources available for LocalMedia (cuae): ip=1(1) v=1(1) c=6(6) l=0(0)

I am unable to use more than one RTP port at a time.


  • Ensure that licenses are not being held up by other application instances holding media resources.
  • Ensure that the Dialogic HMP media engine is not using the default license that allows only 1 RTP stream. This will require applying the correct license. If that doesn't work either, it indicates a faulty install. A fresh install will be required to resolve the issue.

Applicable to release 2.5.1 SR2
