Determining video call rate for ISDN entries
Entering the call rate information when creating a Static entries is relevant for non-Polycom
endpoint entries. However, you can enter the call rate for Polycom endpoints that cannot auto
register with the Global Directory.
For ISDN, the model of the video endpoint determines the rate and the maximum number of
ISDN lines the endpoint is equipped with.
Determining video call rate for IP entries
For IP calls, like ISDN, the model of the video endpoint determines the call rate. There are many
dependencies that affect the call rate of a video endpoint, which include type of model (i.e.,
ViewStation 128 can only make a 128 Kbps call), bandwidth capacity on the LAN and maximum
upload and download speed through your ISP provider. The table below lists the maximum rate
each family model can call at.
Endpoint Model Maximum Rate
ViewStation FX 1920 Kbps
ViewStation and EX 768 Kbps
ViewStation SP 384 Kbps
iPower 4000 Kbps
V-Series 512 Kbps ISDN/ 2000 Kbps IP
