asterisk users - Mar 2012 - Which SIP phone "comply" with COLP feature

Hi,

I would like to test the following COLP use case :

Alice and Bob are both using a SIP phone registered on a Asterisk 10 server.
Alice dials Bob's extension.
While Bob's phone is ringing, Asterisk updates Alice phone screen with
Bob's name, so that at a glance, Alice can check she dialed the
correct number.

Before diving into Asterisk documentation, I would be happy to be
confirmed if one of the following SIP phone support this feature :

Aastra 57i
Yealink T26
Cisco 525G
Thomson ST2030S

Regards

Hello,

i dont know about the other phones but Cisco SPA525g are able to do
this, also the sip updates after a transfer / pickup.

Also the spa 50x can do this without any problem.

best regards
