Cisco Gateway Feature Specifics
Cisco Unified
Videoconferencing 3527 PRI Gateway
1 PRI ISDN port
H.320, H.323 (using Cisco Stack v4.0)
The term audio transcoded video calls refers to the process whereby an audio
stream in a multimedia call can be transcoded from one codec type to another.
Basic and advanced audio coding supported codecs: G.711, G.722, G.722.1,
G.723.1, G.728
G.711 (ISDN) < > G.723.1 (IP) for up
to 30 voice channels.
G.711 (IP) < > G.728 (ISDN) for up to
20 audio transcoded video channels.
The gateway automatically performs
A-Law G.711-to-µ-Law G.711
translation between the IP and ISDN
sides if needed.
Note When your Cisco unit
includes both a gateway and a
MCU, G.728 transcoding is
supported on the MCU only.
