Keycodes

All elements of VoIP trunks and IP telephony are locked by the Business Communications

Manager keycode system. You can purchase keycodes for the amount of access you want for your

system. Additional keycodes can be added later, providing there are adequate resources to handle

them.

System configuration for IP functions

Several sections of the Business Communications Manager must be properly configured prior to

activation of IP telephony. Answer the questions in the following table to determine if your

Business Communications Manager has been correctly configured.

Table 5 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 NetVision 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.

Table 6 Business Communications Manager system configuration

Prerequisites Yes No

6.a Is the LAN functioning correctly with the Business Communications

Manager?

6.b Is the WAN functioning correctly with the Business Communications

Manager?

6.c Have you determined the published IP address for the system? Refer to

“Finding the published IP address” on page 35.

6.d Have the necessary media gateway, IP client, and IP trunks resources been

set? (Refer to “Media gateway parameters for IP service”.)

6.e Has a dialing plan been created, taking into account special considerations

for IP telephony and private and public networking?
