Changing caller info

[ Edited ]



After upgrading some Polycom Soundoint 650 to version we have realized that when an incoming call reaches the phone, the caller number that appears in the display is the "from" field of the INVITE SIP message. 


For example: 


If +34-681213895 calls the Polycom, it appears like sip:681213895@


The INVITE is:


INVITE sip:917831008@ SIP/2.0
Via: SIP/2.0/UDP;branch=z9hG4bKgnpq96109ojt3vhuf0s0.1
From: <sip:681213895@;user=phone>;tag=762724236-1504682592624-
To: "Nieto Francisco Javier"<>



So, how to change the caller info from





Thanks in advance for your help.
