[SR-Users] execute only on INITIAL INVITE

[George Diamantopoulos]

I ain't sure about UPDATEs though. Can they be sent without a to-tag as
well? I believe they can, as one can theoretically immediately follow an
initial INVITE... If that's the case, perhaps you shouldn't check for those
as well:

if ( !has_totag() && !is_method("UPDATE") )

Perhaps a list member with more insight into the UPDATE method could shed
some more light on this...
