System Conditions/Limitations (Peer-to-Peer IP)

Limitations

Add-on-Module:

Dterm IP does not support Add-on Module feature.

Analog Port Adapters:

Back Ground Music (BGM):

Service features requiring continuous voice transmission such as Background Music feature cannot be used because the traffic may reduce overall performance of the Local Area Network (LAN).
