Signal and Alpha Type Support

The Oracle® Enterprise Session Border Controller supports:

• H.245 signal and alpha type UII in the H.323/H.245 TCS as the H.323 calling gateway when the:

  Oracle® Enterprise Session Border Controller calls an H.323 endpoint configured for transparent 2833 support

  calling endpoint’s target is configured as preferred

  If the originating preferred side also sends 2833, the Oracle® Enterprise Session Border Controller forwards it to the transparent side. The Oracle® Enterprise Session Border Controller sends signal and alpha UII support to the called party regardless of whether the calling party sends it, if the call originates from a preferred side to a transparent side.

• H.245 alphanumeric UII for DTMF for H.323 endpoints that do not signal 2833 or contain explicit H.245 UII capability, for stacks configured for transparent 2833 support.

  When the other half of the call is an H.323 endpoint of a stack configured for preferred 2833, the Oracle® Enterprise Session Border Controller translates incoming H.245 UII on the transparent side, to 2833 packets on the preferred side, and vice versa. If the other half of the call is an H.323 endpoint of a transparent stack, the Oracle® Enterprise Session Border Controller relays the H.245 UII messages.

• H.245 signal type UII for DTMF for H.323 endpoints that do not signal 2833, but do signal explicit H.245 UII capability, for stacks configured for transparent 2833 support.

  When the other half of the call is an H.323 endpoint of a stack configured for preferred 2833, the Oracle® Enterprise Session Border Controller translates incoming H.245 signaled UII on the transparent side, to 2833 packets on the preferred side, and vice versa. If the other half of the call is an H.323 endpoint of a transparent stack, the Oracle® Enterprise Session Border Controller relays the H.245 UII messages if both sides support it.
