Music on Hold distorted

[DavidNBH]

Hi All, We are having an issue that we cannot resolve with distorted music on hold (doesn't matter if it is the default wave file or customer specific music file) and it only occurs on 2 of the multitude of PBX clients we have. We have checked everything from the SIP providers to the PBX settings including the IsSupportReinvite is set to 0 in the templates.
The two PBX systems were migrated from V16 to 18 to V20 as were all the others in the same way.

We are completely stumped - please help

Is time sync set using NTP?

 

[DavidNBH]

Yes if this is what you are referring to???

Check this guideline here as well for NTP on the machine.

I looked at the guideline, but I am not sure how to do this on a AWS lightsail platform. I will give it a try. If you have any further details would be helpful.

You will need to SSH to the machine and proceed.
