Keycodes
All elements of VoIP trunks and IP telephony are locked by the BCM keycode system. Answer the
questions in Table 100 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 about determining the
number of keycodes required, see the Keycode Installation Guide (NN40010-301).
System configuration for IP telephony functions
Several sections of the BCM must be properly configured prior to IP telephony activation.
Connect the BCM to the network before completing this checklist. Answer the questions in
Table 101 to determine if your BCM has been correctly configured.
Table 100 Keycodes
Prerequisites Yes No
4.a Complete this question only if you are using VoIP trunks: Do you have enough VoIP
keycodes? H.323 trunks use VoIP keycodes.
4.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. As soon as an IP telephone
is registered, it occupies an IP client, whether it is active or not.).
4.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 PRI lines,
you do not need a separate MCDN keycode for VoIP trunks.
Table 101 BCM system configuration
Prerequisites Yes No
5.a Is the LAN functioning correctly with the BCM? You can test this by pinging
other addresses around the network from the BCM.
5.b Is the WAN functioning correctly with the BCM50a/BCM50e?
5.c Have you determined the published IP address for the system?
5.d Have the necessary media gateway, IP client, and IP trunks resources been set?
5.e Has a dialing plan been created, taking into account special considerations for IP
telephony and private and public networking?
5.f Have thresholds been set for desktop and soft client IP sets for voice quality
monitoring with Proactive Voice Quality Management?
