[Serusers] one to many aliases and voicemail

[Jev]

Hi all,

Having an alias map to a single uri is fine, and if the target uri has 
voicemail enabled that is fine.

What happens if I have a alias that goes one to many, and some of the 
target uris have voicemail enabled? When someone calls a particular 
alias, I don't want ser to redirect to sems at all.

How can I achieve this? Is it possible to detect if a invite has the 
result of an alias (probably by using hints in the sip msg?), and if so 
can I detect how many targets a alias maps to? In basic terms, if 
alias_targets is > 1, then do not redirect to voicemail.

Thanks!
