Caller Name Lookup

[ifm]

Hello,

i want to get the caller name from our crm system and show it in the phone display when a incomming call is established.

With Action URL i can send the caller id to my crm system that is working but how to send the caller name to the Phone?

I do not find any Action URI or Push XML parameter to set the caller name for an incomming call.

I also tried remote phone book but we have 10000 user in our database and it seems that the phone can not make a lookup at each incomming call.

For me that this is an essential feature. Is there any way to realize that?
