I want to provide a public SIP URI for people to call. I have added this into the public dialplan <extension name="toms public sip uri"> <condition field="destination_number" expression="^tom$"> <action application="transfer" data="1000 XML default"/> </condition> </extension> This is working. If somebody from 1004@remote.org calls me at sip:tom@example.com:5080 , my 1000 extension rings. However, the caller-id showing up on my Android phone, which is to extension 1000, is showing 1004@example.com Desired behavior would be for it to show up as 1004@remote.org How can I cause the caller-id to show the remote domain, or at very least, to not lie to me and tell me it's a call from inside my own domain.
