[Asterisk-Users] do extensions must be numbers in Asterisk@Home?

[Joao Pereira]

Hello to all
In Asterisk, SIP clients can be registered with numbers (2001, 2002, 
...) or with names (manuel, maria,...).
But Asterisk at Home only allows SIP registers to be done with numbers...
Is there any way of register SIP users with names and then give them a 
numeric alias?

Thanks
Joao
