Receive 403 when I invite with "allow-anonymous = registered"
I have a SIP interface where set to only allow registered clients. This works for a number of devices.
One device...an ATA doesn't.
He gets registered with this contact.
Contact: sip:5555556005@55.178.66.134:1038;acme_nat=5555556005+55.178.66.134@172.16.0.10
When the same device sends a call, the SBC sends back a 403.
If I set "allow-anonymous" to all, the call goes thru.
I verified the call comes from UDP port 1038 in the contact. The contact header is 5555556005@172.16.0.10. Do I need to do a manipulation on that? Or am I missing something?
