• For the VoIP devices to be managed, define the H.323 protocol options (see
section 6.1.4 “H.323 protocol options” from page 73).
• Create an
alias
entry for every VoIP device. This is done by clicking on the
Add alias
button.
For VoIP end points, you should define the assigned extension number or
MSN here as
E.164 Address
and the name as
H.323 Name
. For VoIP gate-
ways it is sufficient to define the name.
Fig. 21 Entering a VoIP device
Please note, that it always suffices for the VoIP device to register with its name.
In general, the registration is checked to see if the details contained in the regis-
tration match with a configured alias entry. If details have been omitted during
registration (the E.164 address for instance), then these are not checked. A ter-
minal can thus register with just its name. Its extension number is only defined in
the gatekeeper, in the alias entry associated with its name. However if the termi-
nal registers with name and number, you can't just change the number in the
gatekeeper, since the terminal would continue to log on with an incorrect
E.164
Address
, after the change.
If a VoIP device registers with several H.323 aliases simultaneously, each one is
compared with those defined in your gatekeeper and the registration is only
carried out once all aliases have been defined.
• If it is necessary to modify call number processing (see section 5.2.7 “Dealing
with the various ISDN address types” from page 62), then make the entries,
