Asterisk bridges terminate both parties when one leaves

[benlangfeld]

Example code:

Adhearsion.router do
  openended do
    route 'default' do
      answer
      if Adhearsion.active_calls.size > 1
        other_call = Adhearsion.active_calls.first[1]
        logger.info "We already have a call (#{other_call}). Lets join to it!"
        join other_call
      end
      logger.info "Controller terminating"
    end
  end
end

On FreeSWITCH mod_rayo (regardless of who hangs up):

BTW, my observance of this issue was on Asterisk 11.3

Turns out this only fixes the issue for inbound calls. Outbound calls still present the same problem:

Adhearsion.router do
  openended do
    route 'default' do
      answer
      logger.info "Placing outbound call"
      first_call = call
      other_call = Adhearsion::OutboundCall.originate 'SIP/usera' do
        call[:ahn_prevent_hangup] = true
        logger.info "Joining!"
        call.join first_call
      end
      logger.info "Controller terminating"
    end
  end
end
