Keycodes
All elements of VoIP trunks and IP telephony are locked by the BCM keycode system. Answer the
questions in the following table to ensure you have the appropriate keycodes. You can purchase
keycodes for the amount of access you want for your system. Additional keycodes can be added
later, provided there are adequate resources to handle them. For information on determining the
number of keycodes required, see the Keycode Installation Guide (N0060625).
Table 113 Keycodes
Prerequisites
Yes
No
5.a Complete this question only if you are using VoIP trunks: Do you have enough
VoIP keycodes? Both H.323 trunks and SIP trunks use VoIP keycodes.
5.b Complete this question only if you are using IP telephones: Do you have enough
IP client keycodes? (Note: IP clients and IP telephones are a 1:1 ratio. Include
any WLAN wireless IP telephones to your calculations. As soon as an IP
telephone is registered, it occupies an IP client, whether it is active or not.).
5.c If you are using VoIP trunks, do you need to activate MCDN features?
Note: If MCDN is already configured on your system for private networking over
PSTN lines, you do not need a separate MCDN keycode for VoIP trunks.
SIP trunks do not support the MCDN protocol.
System configuration for IP functions
Several sections of the BCM must be properly configured prior to IP telephony activation. Answer
the questions in the following table to determine if your BCM has been correctly configured.
Table 114 BCM system configuration
Prerequisites
6.a Is the LAN functioning correctly with the BCM? You can test this by pinging
other addresses around the network from the BCM.
6.b Is the WAN functioning correctly with the BCM?
6.c Have you determined the published IP address for the system? Refer to
“Finding the published IP address” on page 485.
6.d Have the necessary media gateway, IP client, and IP trunks resources been
set? (Refer to “Media gateway parameters for IP service” on page 488.)
6.e Has a dialing plan been created, taking into account special considerations
for IP telephony and private and public networking?
