Can someone help me with this issue
I’m having issues with followme calls being rejected by my SIP provider due to an incorrect From address
I have tested this by disabling caller id on an extension and then dialing out the same trunk and it works fine the call completes.
The sip INVITE is as follows
INVITE sip:0123456789@888.888.888.888(Provider SIP)5060 SIP/2.0
Via: SIP/2.0/UDP 999.999.999.999(external ip):5060;rport;branch=z9hG4bKPj02fde153-3d4c-437d-a3db-caac859e364f
From: "Anonymous" <sip:anonymous@anonymous.invalid>;tag=61e4c591-8d87-45fc-98b0-1bac25fd3029

When the call is placed from a followme dialing an external number
the call arrives into the system with a from header of
From: Anonymous <sip:anonymous@anonymous.invalid>
then when the call is placed out the SIP from header changes to
From: "Anonymous" <sip:anonymous@10.13.101.13>
because the host isn’t set as anonymous.invalid the call is being rejected
