Was this problem solved? I have exctly same issue. For now, I have not found a way to activate Sip-registration only on one server, and avoid doing so on 2nd server. Making same SIp-registration on both server makes no sense.
I have tried to set ` modparam("uac", "default_socket", "udp:<invalid IP>:5060")` to drop SIP registration if in DB uacreg.socket not specified one of servers, but it does not work.
SIp-registartion still sent from both servers.
