For the 6739i:
You can enable or disable this feature on a global or per-line basis using the configuration files
only.
Configuring SIP Diversion Display on the Phone
Use the following procedures to configure SIP diversion display on the IP phones.
Limitations
•
The diversion header assumes that the the ID of the 'diverted' caller is passed in a URI style
manner.
•
This feature relies on the server supporting and generating the Diversion header; the phone
does not generate the header itself.
•
Diversion header parameters such as counter, limit, privacy, screen, and extension are not
recognized or supported by the phone. However, they are still passed along during the
diversion process.
Note:
If proxy servers exist in the network, it is possible that multiple
diversions can take place on the phones. When multiple diversion
headers are returned in a single 302 response back to the originating
phone, the phone that originated the call (i.e., Tim’s phone in above
example) displays the URI of the newest (first encountered) Diversion
header, but displays the REASON of the oldest (last encountered)
Diversion Header. The phone that receives the diverted call (i.e.,
Roger’s phone in example above) displays the information of the oldest
diverted call (last encountered).
Configuration Files
