To give one example, display updates are very useful in the application I'm using.

I have operators using speed dials for dialing out to dialplan that does a fifo out; so I see what the speed dial is when I press it (e.g. Operator_Call); but then when the operator is connected to the actual caller, the display updates to the CID of the caller she's talking to - very useful.

Also, people using a SIP phone to call into a fifo see the number they dialed (the number that gets them into the fifo).  But when they're answered by an actual phone, their display updates to the number of the endpoint they're talking to.

As I mentioned in my last email, the ignore_display_updates variable did

guessing there must be some use case (in fact a fairly prevalent use case)
where showing the callee is more desirable than showing the caller, but
I'm not aware of what that might be and am curious to find out what the
use case(s) are. Changing the display to callee also seems to affect call
logs on the Polycom, which makes the received call log kind of useless.

Try adding the following line in your diaplan before the bridge command:
 
<action application="set" data="ignore_display_updates=true"/>
(try true and false and see which one works better for you).

     I recently updated my FreeSWITCH installation from 1.0.4 to 1.0.6 and now
     I see a strange behavior with caller ID on Polycom phones when handling
     inbound calls.

     Here is the scenario:

     * Call is from 212-555-2222 (external number not on my softswitch)

     * Call is to 212-555-1001 (number on my softswitch, extension 1001)

     * extension 1001 is a Polycom phone (it's an IP301, but same problem
       occurs on other Polycom models such as the 501 and 601). SIP 3.1.4 and
       SIP 3.1.6 both affected. SIP 3.2.3 doesn't run on the IP301/501/601.

     * on phone 1001, the caller ID will display 212-555-2222 while ringing.
       The moment I pick up, the display will change to "From: 1001" (referring
       to the extension of the phone itself).

     Has anyone else experienced this problem, and does anyone know how to fix
     it? It does not occur with the snom 320 (and I assume it does not occur
     with any of the snom models based on extrapolation).

     While the problem only started when I updated from 1.0.4 to 1.0.6, it's
     entirely possible it's a configuration setting on the Polycom rather than
     a FreeSWITCH issue. I'm not sure. Anyone have pointers about how to
     resolve the problem (or even how to go about investigating the root
     cause)?
