[c-nsp] NAT & Protocol FIXUP

[Tim Jackson]

IOS 12.2(8)T has support for a NAT "fixup" for SIP, although in the past I
have not had much success with it, nor the Pix fixup. But by default it's
turned on in newer releases, but the complete synatax is in the url below.
See:

12.4(2)T has some media path optimizations supposedly, but I have no
experience using these. See:
