To Reproduce

pbx -> opensips -> asterisk The call from pbx triggers a callback from asterisk and waits on wait_for_event. An outgoing call from asterisk creates a b2b session. After the call goes to answered status, I make a b2b_bridge_request and connect the call from pbx and the answered call from asterisk Relevant System Logs

The problem is there is no option modparam("b2b_entities", "b2b_key_prefix", "B2B1") Because the scheme uses two b2b servers b2b -> b2b -> asterisk this causes 2 b2b instances to crash
