Table 8-4 Fields in the Signaling Configuration screen
Field Description
Signaling status Status of signaling module. Ready to receive calls if
registered with gatekeeper, Ready to receive IP-only
calls if not.
Use gatekeeper Check to enable gatekeeper fields.
Status Gatekeeper registration status.
Primary gatekeeper IP
address or host name
Alternate gatekeeper IP
address or host name
IP address or host name of gatekeeper. Required.
IP address or host name of the secondary or backup
gatekeeper. Optional.
Used only when the primary is not available during
startup or when the alternate designated by the primary
gatekeeper is not available.
H.323 prefix (E.164) E.164 dial string prefix for calling the system. Required.
Must be unique among the gatekeeper’s devices and
services.
If the Simplified Dialing service is enabled and registers
with a prefix of 9 (the default), you can’t use 90-99. The
gatekeeper recognizes the 9 as a known prefix and
ignores the second digit.
To configure signaling
1 On the gatekeeper, verify that the H.323 prefix you want to use is
available.
If you register with a prefix that’s already in use, you receive no warning
that something is wrong, but calls to the system will fail.
2 On the Polycom DMA system, go to System Setup > Server Settings >
Signaling Configuration.
3 Check Use gatekeeper.
4 Enter the IP address or host name for the primary gatekeeper.
5 Enter the IP address or host name for the alternate gatekeeper (optional).
6 Enter the H.323 prefix to be used to reach the DMA system.
Users dial this prefix followed by the conference room number.
7 Click Update.
A dialog box informs you that the configuration has been updated.
