Hello all, I'm experimenting with SIP privacy and trying to emulate the message format used by an operator I'm working with. My originate command (from FS_CLI) looks like this: originate {origination_caller_id_name='anonymous@anonymous.invalid ',origination_caller_id_number=631,sip_cid_type=pid,origination_privacy=screen+hide_number+hide_name}sofia/external/ sip:447540xxxxxx@sip.xxxx.com & conference('martyn') Which very nearly works. The receiving mobile says "Unknown" for the caller-id, which is the desired result, but at the SIP level there are a couple of differences from the operator's own format that I wanted to get exactly right. The 'From:' field contains: "anonymous" <sip:631@10.1.1.1> My P-Asserted-Identity field is also the same. A couple of things: (1) Is is possible for the name to get reported as "anonymous@anonymous.invalid" as the caller name, just as I specified, instead of truncated at the @ ? (2) I'm happy with the P-Asserted-Identity field containing the caller number, but can this be removed from the "From" field? When I receive calls from the operator, there is the anonymous name, but the caller number is missing. Regards, Martyn
