4 CH VoIP Media Gateway Expansion Daughter
Board (4VOIPDB-S) — P/N 0891055
24
The VOIPDB daughter board provides:
●
4 channels
●
Connector for the 4VOIPU PCB (combination provides a
maximum of 8 channels per slot)
The VOIPDB is installed on the VOIPU PCB with a maximum
of 3 daughter boards per system. This provides a maximum of
24 channels when combining the 4VOIPU and 4VOIPDB.
When installing a 4VOIPU with a 4VOIPDB PCB, the system uses a consecutive block of 8 trunk
ports if there are 8 ports available.When installing a VoIP PCB, the system automatically assigns
trunk ports to match the card's port capacity. For example, the 4VOIPU with a 4VOIPDB would
take 8 trunk ports. Extension ports are not reserved until an IP phone is connected to the system.
When the Þrst IP phone is plugged in, the system takes the next four consecutive extension ports
available and automatically assigns them as IP ports. The next three IP phones installed will use this
group of ports. When the Þfth IP phone is connected, the next 4 consecutive extension ports avail-
able will be assigned as IP ports.
If the number of trunk ports reserved by the system is a concern (as it could be with the Aspire S
system), install the trunk cards Þrst, then install the VOIPU PCB. This will allow the trunks to be
assigned to the COIU, DIOPU, etc. Þrst. If there are not enough trunk ports available for the VoIP
PCB, the system will still recognize the card and allow it to be used for IP phones.
If the PCB is not going to be used for trunks, the logical trunk ports can be set to '0' in Program
10-03-01 : PCB Setup, but the physical trunk ports are still assigned to the PCB and cannot be used
for any other PCB unless the PCB is deleted from the slot in Program 90-05 : Slot Control.
The Aspire VoIP supports H.323, H.325, and H.245 trunks and compressions of G.711, G.723.1,
and G.729.
