[Spce-user] Subcriber IP authentication

[Alessandro Bolletta]

Hi,
I configured a customer's Asterisk PBX as a subscriber with IP authentication instead of registration in this way, is it correct and secure? It is now currently working for my customer but I'm not really sure about security:

-under Subscriber -> subscriber's Detail -> Preferences -> Trusted Source IP - > create
Source IP: PBX_IP_Address
Protocol: UDP
From-Pattern: ^sip:.*

- under Subscriber -> subscriber's Detail -> Registered Device -> Create Permanent Registration
Contact: sip:pbx_ip_address:5060
Priority: 1
