Per se my SIP delay issues from inbound-only (outbound OK) SIP traffic, up to 60 seconds to originate an audio call, I'm thinking its cuz of the 1:1 mapping in place for the SIP gateway to a WAN IP. Someone else made this decision, I think they're wrong to do so. I figure revert it back to SIP ports under the ACL and be done w/ it. Inspection rules apply to 1:1 as well?

I have this 60 scond delay on all inbound SIP calls, trying to discern whether its the firewall or SIP gateway.
