IP Phone Release Notes 2.4
Will the SIP user agent, Vendor Class ID, HTTP headers remain the same?
Yes. In SIP signaling, the SIP User agent contains the phone’s model number (5xi model
numbers). The SIP User agent continues to reflect the 5xi name on the renamed phones. This
minimizes the impact on the current installed base.
Example
User-Agent: Aastra 55i/2.4.0.1
DHCP option 60 Vendor Class continues to reflect the 5xi model name on the renamed phones.
The following is an example of the Option 60 on a DHCP request:
Example:
Option 60: Vendor class identifier = "AastraIPPhone55i"
In XML, the phone sends the model number (5xi model numbers) in the HTTP headers. The 5xi
models numbers continue to be sent by the phone in HTTP headers in XML applications on the
renamed phones.
