Hello Bogdan, thanks for this info. Concerning Question 2 I try to find an example with opensipsctl to disable a destination address (destination address are in the database): opensipsctl fifo ds_set_state i 1sip:127.0.0.1:5080 # set inactive Or am I doing wrong something here? Does this also update the database table 'dispatcher' or is this non-persistent?
