[asterisk-dev] Limiting Number of registrations

[Rafael Vidal Aroca]

    Hi guys,

    i've been playing with chan_sip.c trying to add an interesting 
feature in asterisk for voip providers, that blocks a second SIP peer 
against registering in the server.

    That would work like that: first
    client connects -> OK
    second client tries to connect while the other is connect -> ERROR

    So, i used _sip_show_peers, and checked if the user is on line. If 
it is online, it rejects the register. Now a great problem arises! The 
update is exactly like the first register, so after the first register, 
the client can't keep the register correctly.
   
    I don't know if i explained well, but the ideia is to block 
simultaneos connections. Does anyone have an idea or hint of how that 
could be done?

    thanks
