Part of this thread detailed H.323 vs MGCP; does anyone have input on 
the impact of a SIP trunk to the voice gateway rather than H.323?  Is 
there any SRST impact?  We deployed H.323 primarily because we can't 
depend on our WAN link, and with the new call preservation stuff for 
H.323 in 12.4T that's alleviated part of our issues.  But delivery of 
caller name would be a big win.
