Telephony Cards - Can I use a Sangoma card on a Virtual Environment

No. Installation of Sangoma card on virtualized environments is not a supported implementation by Sangoma Tech Support due to the fact that his kind of environments may have issues meeting the minimum communication performance required between the driver (DAHDI) and the Sangoma card in order to keep a good quality.

Some issues that you could experience on virtualized system are:

• Latency problems

• Hardware underruns 

• Unable to place and receive calls

• drop calls

• Audio Quality issues
