As with any Voice Over IP (VoIP) implementation, there are several issues that should be
considered when setting up IP Networking on the Aspire.
These issues are discussed in detail in the Aspire Voice Over IP Manual. Please refer to
this before installing IP Networking.
Refer to Appendix (page 237) for an example of setting up a network using ISDN or
IP connections.
Using H.323 protocol for voice transmit protocol, it is possible to network Aspire systems. VoIP
can be used to network the Aspire S, M, L, and XL systems.
● Using IP Networking the maximum quantity of simultaneous calls is limited by the availabil-
ity of resources on the VOIPU PCB's installed. A maximum of sixteen 16VOIPU PCB's can
be installed each with a 16 port expansion daughter card giving a maximum of 512 speech
channels (this number depends on the system and the NTCPU type).
● The maximum quantity of calls may also be reduced by the compression mode (CODEC type)
of the VOIPU PCB's, this is selectable by the installer in Program 84-12-28. Refer to the
Aspire Software Manual (P/N 0893200) for further details.
When using IP Networking, keep the following items in mind:
● In order to keep the audio quality, prevent sending and receiving unnecessary packets by:
● not using a repeater hub with the Aspire system.
●
turning off the Spanning Tree feature, if possible.
● Disable the SIP NAPT router in Program 10-12-06 (set to 0) to prevent the IP address from
being changed by any other equipment.
● Use equipment which provides an Auto-Negotiation feature, if possible.
● The UPnP feature is not guaranteed to work with the Aspire system.
● In order to use the Networking feature, the Aspire M/L/XL NTCPU must have a Feature
Upgrade or Enhanced PAL chip installed. The Aspire S requires the ENTU LAN card in order
to use VoIP PCBs.
● IP addresses are required for each site's NTCPU, VoIP cards in each site, and the default gate-
way (inside IP address) from each site's routers.
Ring groups are NOT shared between networked systems. The only way you can ring a phone in
Site B and Site A at the same time is to DIL a trunk to an extension or a virtual extension at Site B
and program Call Forward Both Ring to an extension or virtual extension at Site A.
