Hi All

We are unable to hear any voice where as in tcpdum it shows that RTP is flowing both ways

ERROR CONDITION
---------------
-- Executing Dial("SIP/2001-f6c4", "SIP/2000|20") in new stack
    -- Called 2000
    -- SIP/2000-0ead is ringing
    -- SIP/2000-0ead answered SIP/2001-f6c4
    -- Attempting native bridge of SIP/2001-f6c4 and SIP/2000-0ead

Have searched web and archive w/o good results.
