This is the normal behaviour. When you use auth credentials against a peer, the
from header is changed to the auth credetials for the challenge.
Anyways, you have ther PAI header with the subscriber information. From the
SPCE Handbook section 3.4:
"If you do NOT authenticate against a peer host, then the caller CLI is put into
the From and P-Asserted-Identity headers, e.g. "+4312345"
<sip:+4312345 at your-domain.com>. If you DO authenticate, then the From header is
"+4312345" <sip:your_peer_auth_user at your_peer_auth_realm> and the
P-Asserted-Identity header is as usual like <sip:+4312345 at your-domain.com>. So
for presenting the correct CLI in CLIP no screening scenarios, your peering
provider needs to extract the correct user either from the From Display-Name or
from the P-Asserted-Identity URI-User."
