[SR-Users] Issue with dlg_setflag vs. setflag

[Anthony Messina]

I didn't understand that properly from the dialog module README in 6.10.  
dlg_manage():

"Process current SIP request with dialog module. It is an alternative to 
setting dialog flag for initial INVITE and Route-parameter-callback execution 
for within-dialog requests."

Your explanation was very helpful.  Thanks Daniel.  -A
