[Asterisk-Users] 2 asterisks connected but trying to bridge call and this is not wanted

[Anton Krall]

Guys.. I have a problem with 2 asterisks connected together but each time
one tries to call another I get this:

    -- Executing Dial("SIP/fozy-dfbc", "IAX2/voip-gw/201|60|mwtWT") in new
stack
    -- Called voip-gw/201
    -- Started music on hold, class 'default', on SIP/fozy-dfbc
    -- Stopped music on hold on SIP/fozy-dfbc
    -- Call accepted by 10.0.101.1 (format ilbc)
    -- Format for call is ilbc
    -- Hungup 'IAX2/voip-gw-2'

And on the other side

        Channel  (Context    Extension    Pri )   State Appl.         Data

(Empty)
2 active channel(s)
2 active call(s)

Why is it trying to make several channels for the same call? Also, seems is
trying to bridge the call which I don't want since I need the asterisks to
stay in the middle since both asterisks are behind nats but they are
connected using openvpn.

Any clues that might help?
