ADDITIONAL INFORMATION:
You can specify a maximum of 10 SIP devices. However, Avaya recommends that out of the 10 SIP endpoints only one endpoint should be a Device Adapter UNIStim endpoint.
If the user wants to include two or more Device Adapter UNIStim endpoints, then Avaya recommends that you set the Max. Simultaneous Devices field value to 1. This is called Sequential Registration and not MDA.
