Related question:

If using OpenSER in front of * as a registrar/proxy, how should the sip 
clients be set up for outgoing calls?

All our INVITES will come from the ser IP addresses (there are 2 
currently) and we so I need to match on username and host combination.

If I set up the client sip entry as peer, then the username is not 
looked up, only the host settings.

If I set up the client as user, then the host setting is ignored and 
anyone could log in to that SIP account, just knowing the username.

Setting it as friend works, but my feeling is (and your comment above 
re-enforces this) that this is not the way to do it.

How do I set up so that the host MUST match one of our OpenSER IPs AND 
the username must match?

Thanks.
