Chapter 21: Enterprise VoIP Network Management
AltiWare ACC 5.1 Administration Manual 283
• It is recommended that you use 20ms frame size for G.711 and G.729 when
configuring a Codec Profile.
• When different IP devices using various codecs connect to the server through a
Public Pipe, the system will aggregate the total bandwidth of all connections. If the
total bandwidth exceeds that specified in the Bandwidth for VoIP box, the system
will reject additional connection requests.
Configuration example
Suppose your company has a T1 line configured as half voice PRI and half data service.
There are 12 remote employees using IP phones connecting to the AltiGen system.
Because bandwidth is limited, you would like to regulate the bandwidth used by VoIP.
You have set up remote IP phones using G.729 with 20ms frame, and you want to limit
the number of concurrent VoIP sessions to 6. If you enter 180 in the Bandwidth for
VoIP field, the system will show that 6 G.729 sessions are allowed.
Configuring AltiServ Behind NAT
Your AltiWare system should be inside a firewall/NAT router. If your AltiServ is
supporting remote IP phones, IPTalk or AltiClients, you need to configure AltiServ and
the NAT router to make AltiServ work properly behind NAT. Port forwarding configuration
on the firewall/NAT router is required. If you’re not sure how to configure your firewall/
NAT router, please consult your firewall/NAT router manual or vendor. AltiGen Technical
Support will not be able to help with this.
Important: If your firewall/NAT router supports SIP, you need to FULLY disable this
feature on the firewall/NAT router, or conflicts may occur between AltiServ
and the firewall/NAT router. In this case, remote IP phones might not work
or might behave strangely. Again, please consult the firewall/NAT router
manual to find out how to do this.
Take the following steps:
1. Make sure the AltiServ system uses a private static IP address, for example,
10.10.0.8. Do not use DHCP on the AltiServ system.
2. Define the range of the local IP addresses (see “To define an address range” on page
282). Make sure the AltiServ system is included in the range. If the range is not
defined correctly, all the IP phones will not work.
3. Set local IP network ranges to private. Multiple private networks can be added.
4. On the IP Networks tab, in the NAT Support panel, check Enable SIP NAT
support and Enable H323 NAT support. Except, if the NAT router is H.323-aware
(for example, a Fortinet router) do not enable H323 NAT support.
