I just created a new System Call Handler (UC 10.5), and am trying to import my .wav file, but when I attempt to record from my computer, I receive a java (v8 u171) error:
Could not open the Audio Mixer Line to record on.
Audio Format: PCM_SIGNED 8000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian,
Line Format: PCM_SIGNED 8000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian,
Exception: javax.sound.sampled.LineUnavailableException: line with format PCM_SIGNED 8000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian not supported.
This is definitely a Java error. It only happens after I click on the record button. I have tried to create a recording from my phone and changing it. I have tried to play back from and phone and changing it as well, but still no success. I have also made sure my UC is also whitelisted. I don't have an issue playing messages, just importing them from my computer. Below is a screenshot of the error as well.
Solved! Go to Solution.
Why dont you try using Audio text manager. You can download that from the below link.
Hope this helps!

If formatting is the problem, try using the website g711.org to upload, convert, and download the wav file. I have used this to convert a variety of music and announcement file formats for upload to CUCM.
Thanks for the response. Unfortunately, formatting isn't the issue. I can't even get to open the file explorer to select the file. Java is definitely the culprit on this. I'm just running out of ideas on what to change so that it can play nice with UC.
