[SR-Users] sip_trace vs uac_reg

I'm not sure there's any way to intercept endogenously generated 
specialty requests (like uac_reg requests) in route script. If there is, 
it would only be in something relatively low-level like the onsend_route.

uacreg may use TM callbacks internally to catch responses, but that 
doesn't mean it exposes them into route script hooks. I have never seen 
or heard of such a mechanism.
