* When no USB port is available, and connection is made via the AUDIO I/O port
* When USB bus power alone is insufficient (such as when playing back music at high volume)

The IPA-01 is an adapter that connects Yamaha's Projectphone conference systems (PJP-100H and PJP-100UH) with IP phones. When the IPA-01 is connected to a Projectphone, calls can be made between the Projectphone and other telephone devices through an IP phone connection.
* Does not support telephones other than IP phones.
* Depending on the IP phone, this configuration may be unusable due to echo or noise.
