Sip-trunk

i am working with PBX Firmware 1.816.210.58-1 and Version 2.10 of FreePBX.

One part ist connected to a Bintec - Router with Trunk - Name R1200 and the following Details:

username=R1200
type=peer
secret=SECRET
host=192.168.130.2
insecure=very
fromuser=R1200
context=FROM-ISDN
canreinvite=no

The Incoming USER-Context ist the same, it’s called FROM-ISDN.
This context ist Working, here’s the output:

Executing [[email protected]:1] Set(“SIP/R1200-0000003d”, "[email protected];user=phone>") in new stack

[2012-11-26 10:32:46] VERBOSE[4050] pbx.c: – Goto (from-trunk,00,1)

Now i have the Problem, that the Recieved Calls in the User Portal are always sent from the Context “R1200”

Datumsort	Uhrzeit	Anrufer-Nummer	Anrufer	Angerufener	Dauer	Monitor
2012-11-26 	10:32:46 	"07141871220" 	R1200 	00 	14 sec 	

Where can in change this Description R1200 to the Caller-ID?
