Miscellaneous Settings

If multicasting is permitted, then the Phone Adapter will allow IP multicast packets to be forwarded to the appropriate computers. Select the types of multicast transmissions to allow: Disabled (none), Inbound Only, Outbound Only, or Inbound and Outbound. The default is Disabled.

Num of Ports Reserved. Select the number of ports you want to reserve: 256, 512, or 1024. The default is 256.
