IVR prompts or RADs not playing

Article ID: 52428 - Last Review: March 18, 2016


Prompts cease to play on certain IVR ports when using an MSL based MiVB platform. Ports start to return RNA (ring no answer warnings). Ultimately this can lead to the MitaiProxyServer service crashing. 


IVR port logging reporting that the TX channel is closed indicated in the logs by TXOpened [False]:

May also cause alarm ALM0015 - IVR Bad Audio File to be fired.



This is caused by a media server fault in MSL based MiVB platforms running versions earlier than MiVB 7.2.   



A reboot of the MiVB that the ports reside on resolves the issue temporarily.


 Upgrade the MiVB's to release 7.2 or above. This was resolved due to a code re-work to address multiple media server issues.


MiVB releases prior to 7.2
