Without knowing more about your account and provider, perhaps they have had issues with users getting their accounts hacked, so they added on IP authentication in addition to diget? Or maybe they've had issues with IP-auth people still having DoS type attacks by sending fake INVITEs and using up credit a bit at a time, so they added on digest? Or maybe they're paranoid?

Subject: [Freeswitch-users] OT: SIP and IP spoofing
My sip gateway provider are using both IP address locking (only my servers IP addresses can use my gateway account) and Digest authentication on every call.
I asked why and they said that the account would be vulnerable to IP spoofing otherwise. Is that possible? I mean, if someone fakes my servers IP address in the packets, shouldn't the responses be sent back to my server and not the one creating the fake packets? Are there any other reasons to use both ip locking and digest authentication?
