Before you Upgrade
Please Read Before Upgrading Your Phone
If you have a firmware version on your phone prior to 2.3, please read the following IMPORTANT
information before upgrading the phones:
• LLDP is enabled by default.
If LLDP is enabled on your network, the phones may come up with different network settings.
For more information about LLDP, see the Aastra SIP IP Phone Administrator Guide.
• Support for DHCP Options 159 and 160.
If the DHCP server supplies Options 159 and 160, the phones will attempt to contact the
configuration server given in these options. For more information about Options 159 and 160,
see the Aastra SIP IP Phone Administrator Guide.
• HTTPS validation.
If you are using HTTPS and the certificates are not valid or are not signed by Verisign,
Thawte, or GeoTrust, the phones fail to download configuration files. For more information
about HTTPS validation, see the Aastra SIP IP Phone Administrator Guide.
Before you Upgrade
• Watchdog task feature.
If the phone detects a failure (for example, a crash), the phone automatically reboots. For more
information about the Watchdog feature, see the Aastra SIP IP Phone Administrator Guide.
Note: If you factory default a phone with Release 2.3 and above
software, when the phone reboots, it attempts to connect to
rcs.aastra.com. There is no personal information transmitted from the
phone and the phone continues to boot up as normal.

(For Administrators)
User Interface Feature
Support for Additional Codec Types and
Codec Priority Selection
(For Administrators)
Release 2.4.1 provides a new feature that allows an

with Compact SIP Headers defined in RFC 3261.
Release 2.4.1 includes support for a additional code

SIP Feature
Configurable Support for Compact SIP Header
Release 2.4.1 provides a new feature that allows an Administrator to shorten the length of a SIP
packet by using the compact form. This feature is in accordance with Compact SIP Headers
defined in RFC 3261.
For example, the following SIP header is the long format:
Via: SIP/2.0/UDP
10.50.91.2:5060;branch=z9hG4bK571ebe0c;rport=5060;received=10.50.91.2
From: "Unknown" <sip:Unknown@10.50.91.2>;tag=as19d00fc8
To: <sip:1106@10.50.110.54:5060;transport=udp>;tag=916699998
Call-Id: 73cad5456806f3a7768d17e8617279d7@10.50.91.2
CSeq: 102 OPTIONS

Page 9
SIP IP Phone Models 9143i, 9480i, 9480i CT, and 675xi Series Phones Release Note 2.4.1
New Features in Release 2.4.1
The following SIP header is equivalent to the above SIP header, but uses the short (compact)
format instead:
v: SIP/2.0/UDP
10.50.91.2:5060;branch=z9hG4bK571ebe0c;rport=5060;received=10.50.91.2
f: "Unknown" <sip:Unknown@10.50.91.2>;tag=as19d00fc8
t: <sip:1106@10.50.110.54:5060;transport=udp>;tag=916699998
i: 73cad5456806f3a7768d17e8617279d7@10.50.91.2
CSeq: 102 OPTIONS
By default, the IP Phones use the long format. However, an Administrator can provision the short
(compact) format using the configuration files. The Aastra Web UI does not support this
configuration feature.
Enabling/Disabling the Compact SIP Headers Feature
To enable/disable compact sip headers use the following configuration parameter:
• sip compact headers
Parameter –

Description Enables or disables the IP phones to use compact SIP headers in the
Format Boolean

Configuring Customized Codecs Using the Aastra Web UI
Use the following procedure to customize codecs for the phones using the Aastra Web UI.
Aastra Web UI
1 Click on Advanced Settings->Global SIP->Codec Preference List.
New Features in Release 2.4.1
2 In the Codec Preference List 1, select a codec 9 (with its payload type) you want the phones to use. Valid values are:
All
Basic (G.711 u-law, G.711 a-law, G.729)
G722
G711u/8K
G711u/16K
G711a/8K
G711a/16K
G729
G726-16
G726-24
G726-32
G726-40
BV16 (8K)
BV32 (16K)
L16 (8K)
L16 (16K)
Notes:
1. Setting the Codec Preference List 1 to “All” ignores the packetization interval (ptime). The packetization
interval setting defaults to 30, which is the default for all codecs.
2. Setting the Codec Preference List 1 to “All” automatically sets all other codec preference fields 2 through 10 to
“None”.
3. Setting the Codec Preference List 1 to “Basic” and all other codec preferences in 2 through 10 to “None”,
forces the phone to use only the basic codecs as in previous releases (G.711 u-law, G.711 a-law, and G.729). If you
select an additional codec to use in the codec preferences 2 through 10 fields, those codecs are added to the list of
Basic codecs for the phone to use.
