[Kamailio-Users] disable simultaneous register

[Luis Guaman]

Hi Daniel,
We have already updated 1.4.3 to 1.5.0 version and it is workin great!
I have used save() function with flag 0x04 and it allow to register uac 
again with no previous un-register...cool!

We need just one user concurrent registered per account. We can not use 
modparam("registrar", "max_contacts", 1) because when the computer hangs 
we need to wait until register expire to register again.
We want to know how to detect the event when some same second ua 
register, in order to send a reply message to the first registered uac 
to  block outbound calls (just one balance per user).

Thanks in advance


Luis
