Hi guys

Has anybody encountered a situation where .gsm recordings are corrupted if the Asterisk instance is running in a virtual machine?

Specifically running Asterisk in MS Azure cloud VMs on CentOS 7 inside the hosted instance.

Switching to .wav files solves the problem, I can only guess that .gsm encoding is very time sensitive or reliant on timer behaviour that cannot be guaranteed in a virtual instance.

Is this assumption correct? Any pointers about how to make GSM encoding work right on a VM?

Thanks!

Stefan
