[Serusers] aliases and table and ringing two phones using same ID

[Iqbal]

Hi

I am trying to get a call blasting kind of thing setup, where a call to
alias
101 goes to abc at xyz.com and qwe at xyz.com

In 0.8.x this seemed possible by adding alias 101 for both addresses, not
sure if this is/was the correct way of doing it, however in 0.10 it
seems as if the username in alias table is set as a primary key, which
means i cant do this, is this a feature, if so, whats the best way of
ringing multiple phones
