Maybe you need a better name for it than server. To me server means
the hostname / address of the other side of the SIP conversation, aka:
FROM.

You can use SipAddHeader to make your own X-blah tags for your
packets, and then pick them off on the other side. I don't seem to
understand what you mean by 'server', despite my command of the
english language. Perhaps you want
${SIPUSERAGENT}
