I want to know if it is possible to change the 'SIP From Header' in the invite message that is send to the SIP provider?
This SIP provider is requesting it to be this way, for reasons I don't know.
Below is an example for what they request.
Example:
"INVITE" request [1 INVITE]
INVITE sip:0123456789@SIPPROVIDERTRUNK.com SIP/2.0
Via: SIP/2.0/UDP 192.168.41.152;branch=z9hG4bK_AI2022Sep290340634072320379541;rport
To: sip:012345678@SIPPROVIDERTRUNK.com
From: <sip:9876543210@CLIENTFROMFIELD.com>;tag=AIBC88FCC5D6195E22
Can anyone tell me how I can do this on the system?
