1.1 What is New
IP Office 5.0
The following changes specific to H323 IP phone support have been made as part of the IP Office 5.0 release.
· Embedded Memory Card Usage
In order to simplify H323 phone installation and maintenance, a number of changes have been made, employing
the Embedded Voicemail memory card supported by IP406 V2 and IP500 control units.
· Automatic File Loading
Using the Embedded File Management option within IP Office Manager, the option File | Upload Phone Files
will transfer all necessary phone firmware files required for phones supported by IP Office 5.0 to the memory
card. Those files are then available to the phones if the IP Office is configured as the HTTP/TFTP server for
phones.
· Auto-Generated File Operation
If the IP Office is configured as the HTTP/TFTP file server for H323 phones, the Embedded Voicemail memory
card is used as the file store. The file server normally requires copies of various .scr and .txt files to be
present. For IP Office 5.0, if those files are not present on the memory card, the IP Office will auto-generate a
suitable file when it is requested by a phone.
· Extension Quality of Service Measurement
Through the IP Office configuration, H323 IP phones (1600 Series, 4600 Series and 5600 Series) can be enabled
to send QoS information to the IP Office system. For other types of extension, when their call involves a VCM
channel, QoS information is available. The QoS information is round trip delay, jitter and packet loss. This
information is used in a number of ways.
· QoS Display
Within the IP Office System Status Application (SSA), the current QoS measurements are shown for calls. This
is in addition to the QoS measurement already displayed by SSA for IP trunks.
· QoS Alarms
QoS alarms thresholds can be set within the IP Office configuration. On calls where a threshold is exceeded,
an alarm is generated at the end of the call. The alarm will contain the maximum value of all the QoS
measurements. QoS alarms are shown in SSA. They can also be specified for output as alarms via SNMP,
Syslog and/or email.
· Resilience
IP Office 5.0 includes support for a number of 'resilience' features within an IP Office Small Community Network.
This includes support for registered H323 phones and their users if the IP Office with which they are registered
should not be available on the network. For details of resilience operation refer to the IP Office 5.0 Manager
manual.
· VLAN Setting
This option within the IP Office configuration (System | LAN1/LAN2 | VoIP) is applied to H323 phones using the IP
Office for DHCP support. If set to Disabled, the L2Q value indicated to phones in the DHCP response is 2
(disabled). If set to Not Present, no L2Q value is included in the DHCP response.
IP Office 4.2
The following changes specific to H323 IP phone support have been made as part of the IP Office 4.2 release.
· Support for 1600 Series Phones
IP Office 4.2 Q4 2008+ supports the 1603, 1608, 1616 IP phones.
· HTTP Server Support
For Avaya IP phones using IP Office DHCP, the address of the HTTP server from which those phones should
download their software and settings files can now be specified in the IP Office configuration. 4600 Series and
5600 Series phones attempt to load files via HTTPS and then HTTP before falling back to TFTP. 1600 Series IP
phones only support HTTPS or HTTP.
· HTTP-TFTP Relay
The IP Office control unit supports HTTP-TFTP relay for HTTP file requests from phones.
· HTTP-TFTP Using an Embedded Memory Card
For IP Office 4.2, using the Embedded Voicemail memory card is also supported for HTTP file requests for
up to 50 IP phones. This is done by setting the TFTP Server IP Address and HTTP Server IP Address
to the control unit IP address. This method is supported for up to 50 IP phones.
· HTTP-TFTP Using IP Office Manager
For the IP Office 4.2 Q4 2008 maintenance release, HTTP-TFTP Relay is support using IP Office Manager
as the TFTP server. This is done by setting the TFTP Server IP Address to the address of the Manager
PC and the HTTP Server IP Address to the control unit IP address. This method is supported for up to 5
IP phones.
